1.0 Drought Response PrefaceEast Gippsland Water’s (EGW) Statement of Obligations (SoO) requires the Corporation to develop andimplement an effective Drought Response Plan (DRP) for each water supply system with the intent of providing aframework for ensuring timely and effective response to water shortages.

The SoO also requires EGW to review and if necessary amend its DRP’s at intervals of no more than five years orwithin twelve months of either:

the lifting of any period of restriction imposed under the Corporation’s DRP; and any major change occurring to works or arrangements for conserving water for, or supplying water to, any

water supply system operated by the Corporation.

The outcomes of the latest Mallacoota Water Supply Demand Strategy (AECOM, 2010) proposed the following inorder to improve reliability of supply to Mallacoota:

Improve reliability of supply by:- completing water use audits of high water users to identify potential water efficient projects;- investigating the possibility of supplying additional recycled water to the golf course;- constructing new groundwater bores;- increasing EGW’s groundwater licence to 220 ML/yr;- covering the raw water storage to reduce evaporative losses if funding is granted- continuing with leak detection and management work; and- supplying an alternative water source to the caravan park.

Provide emergency supply by:- water carting.

This report is intended to form an update to the previous DRP titled ‘Drought Response Plan for Mallacoota’prepared by SKM in 2006.

This review and update of the Mallacoota DRP includes:

revision of the current system configuration; re-structuring the DRP; update of statistics relating to drought history; revision of restriction triggers based on the updated system configuration; update of available drought response options; revision of the previous action plan; identification of information gaps; and recommendations.

Text in italics are direct excerpts from the previous DRP (2006).

This DRP should be read in conjunction with the Mallacoota Water Supply Demand Strategy (2010) and shouldbe updated in the event of any changes to the existing water supply system or its operation.

EGW is currently in the process of applying for an additional 100 ML groundwater allocation which will increasetheir groundwater entitlement to 220 ML/yr. The infrastructure to supply this increased volume is currently in placeand once licence approval has been granted a further update to this DRP will be required.



2.0 IntroductionThe aim of this DRP is to ensure a timely and effective response to water shortages, with the aim of minimisingthe social, economic and environmental impacts of such shortages.

There are two components involved in securing an adequate water supply in times of drought. These are:

the provision of an adequate supply system to satisfy current and future demands for design droughtconditions, ensuring that shortfalls in supply are within 'acceptable' levels; andthe definition of the actions required when water supply shortfalls occur.

The first component represents the long term planning actions which result in a certain level of infrastructuredevelopment. A high level of service (i.e. where shortages in supply are very infrequent) requires a high level ofinvestment in infrastructure. This means that consumers are paying a large premium every year to insurethemselves against potential shortfalls in supply during relatively infrequent drought events.

The second component relates to management actions which are required to minimise the impacts of shortfalls insupply. These actions complement the long term planning process. While the Drought Response Plan relatesspecifically to the second component, the short term response needs to be based on a good understanding of thelonger term security of supply for the supply system, as this defines the supply context for a DRP.

A full drought management plan for a water supply corporation involves an appropriate combination of long andshort term components, focussing on the actions to be taken and/or considered by EGW in pre-drought, droughtand post-drought periods.



3.0 System Description

3.1 Description of the Water Supply SystemMallacoota is supplied with surface water from the Betka River and in periods of low flow with groundwater fromtwo bores. Low flow periods in the Betka River have become increasingly common and groundwater has becomean integral part of the supply to Mallacoota.

3.1.1 Surface Water Extraction

Surface water is pumped from the Betka River at a maximum rate of 1.2 ML/day via a 6 km long 150 mm diameterasbestos cement rising main to a 41 ML raw water storage at the water treatment plant. Surface water is pumpedfrom a pumping pool on the river up to a balancing tank by a submersible pump, before being transferred to thetreatment plant by a larger pump station. The maximum rate of water transfer is limited by the WTP (WaterTreatment Plant) capacity and by the transfer infrastructure (pipeline and pump station), which prevents thesystem from delivering the maximum daily bulk entitlement from the river when it is flowing (1.55 ML/day).

3.1.2 Groundwater Extraction

When the Betka River is not flowing, groundwater is extracted from one of two groundwater bores as long asthere is capacity in the raw water storage. One of the groundwater bores is located near the Betka River surfacewater off-take and the other near the treatment plant. Groundwater from the off-take bore is pumped to thetreatment plant via the same pipeline that transfers surface water to the treatment plant.

The treatment plant bore and off-take bore are fitted with pumps with capacities of 12 L/s and 7.4 L/s respectively.The long term pumping rate of the two bores was assessed in 2000 and it was concluded that the bores could bepumped continuously at 6 L/s for 60 days (Geo-eng, 2000). The report suggested that it would be preferable tooperate the bores on a 24 hour cycle of 16 hours pumping and 8 hours recovery, allowing for partial groundwaterrecovery and a longer period before maximum drawdown is reached (i.e. longer than 60 days).

Review of recent groundwater extraction rates indicate that the treatment plant bore was providing 0.55 ML/dayover a 60 day period, while the Betka bore was providing approximately 0.4 ML/day over a 60 day period

The treatment plant bore has a higher transmissivity than the off-take bore and therefore provides a more reliablesupply of groundwater. It is also further away from the Betka River and is less likely to impact on surface watervalues. For these reasons the treatment plant bore is relied upon more heavily than the off-take bore.

3.1.3 Water Treatment Plant

The water treatment plant has a capacity of 1.0 ML/day. In the peak periods this capacity is lower than thedemand and therefore the treatment plant constrains the system. However, during these peak periods the systemis usually also constrained by supply of groundwater to the treatment plant. The bores are generally relied uponto fill the storages in preparation for the peak holiday periods. This results in increased localised drawdown in theaquifer and reduces the production of groundwater from the bores due to the head losses.

The groundwater is high in iron and manganese and is aerated prior to entering the treatment plant to reducealgal blooms from occurring in the raw water storage.

From the treatment plant, treated water is delivered to a 240 kL clear water tank for release to customers eitherdirectly or via a 23 ML clear water storage at the treatment plant. The clear water storage is covered, howeverthe raw water storage is not, which contributes to system losses through evaporation.

A schematic of Mallacoota’s water supply system is shown in Figure 1.



Figure 1: Mallacoota's Water Supply System

3.2 Changes to the Supply SystemA number of changes have occurred since previous droughts. These include:

The introduction of a two part user - pays tariff system for urban consumers in Mallacoota in 1993/94. Underthis system users pay according to the amount of water they consume.The commissioning of a full water treatment plant in July 1997, which replaced the sodium hypochloritedisinfection plant.The drilling of two new drought relief bores in 2000 to replace the previous groundwater bores.

Further changes since the development of the previous DRP in 2006 include:

Increase to groundwater licence to 120 ML per year Introduction of a single volumetric rate for water consumption in all districts ($1.25/kL) – 2009 Upgrade of the groundwater pump at the treatment plant bore to a capacity of 12 L/s Aeration of groundwater to prevent algal blooms in the raw water storage Clear water storage covered

EGW is currently in the process of applying for an additional 100 ML groundwater allocation which will increasetheir groundwater entitlement to 220 ML/yr. The infrastructure to supply this increased volume is currently in placeand once licence approval has been granted a further update to this DRP will be required.



4.0 Objectives

4.1 Drought Response Plan Objectives4.1.1 General

A set of objectives is required for a Drought Response Plan (DRP) in order to give the plan direction and purpose,and to facilitate an evaluation of the effectiveness of drought assessment and response activities.

Goals and objectives to be considered in a DRP are:

Strategic - addresses the overall objectives for drought response and tie in with other strategic objectives fora corporation;Planning - specifically related to the creation of a definite plan; andOperational - translates the strategic objectives into specific operational objectives.

4.1.2 Strategic

To ensure a systematic, timely and efficient response to drought and minimise its impact on customers by:

Ensuring timely warning of any water shortages which might occur during future drought events andimproving the preparedness to deal with such shortages when they occur.

4.1.3 Planning

To ensure that:

the plan identifies all the necessary steps that need to be taken throughout a drought including clear triggervariables that instigate certain action;the plan is subject to regular review as the system develops and as more information becomes availableduring the pre-drought phase;the plan is reviewed throughout the course of drought and adjusted where necessary, and that all actionstaken be evaluated after the end of the drought; and

the plan is consistent with the most recent revision of the Mallacoota WSDS.

4.1.4 Operational

To ensure that:

during times of severe water shortage, ensure that as a minimum, a supply of at least 60 litres/consumer/dayis provided. This is the minimum volume required to meet basic human needs (UN, 1992);the most efficient use is made of water resources during periods of water shortage;minimum flows are maintained to meet any downstream operational commitments or environmentalrequirements; anda reliable assessment of drought status is provided so that EGW is aware of what stage of drought they arein and how severe the drought is likely to be.



5.0 Action Plan for Responding to Drought

5.1 IntroductionTo ensure that EGW’s water resources are managed effectively during times of drought an action plan forresponding to drought was developed. This action plan takes the form of a number of pre and post droughtactivities, along with a flowchart detailing critical actions.

5.2 Action Plan FlowchartThe flowchart contained in Appendix A summarises the below action plan into a decision making framework toassist EGW’s management and operations staff. This flowchart could be used as an input to EGW’s ISES modelto assist with streamlining current processes.

5.2.1 Water Restriction Trigger Levels

The restriction trigger levels are based on the total volume in storage (capacity 64 ML) providing one month leadtime between restriction levels assuming that both groundwater bores are operating normally at a pumping rate of0.55 ML/d. In the event that there is a reduction in groundwater production capacity, alternative trigger levelswould be required to provide a similar lead time between restrictions.

EGW shall review the restriction trigger levels if there is a reduction in groundwater production capacity, takinginto consideration the length of time the groundwater production is expected to be reduced, volume in storage, thecurrent demand, rainfall forecasts and the level of flow in the Betka River.

The water supply storage levels presented in Table 1 are the restriction triggers set by EGW in Mallacoota’s 2006DRP.Table 1: Restriction Triggers

5.2.2 Voluntary Restrictions

Voluntary restrictions are to be introduced when the Mallacoota storage drops below the listed storage volumes(specific to each month), given in Table 1. Before instigating these restrictions, EGW must be satisfied thatreduced stream flow will be an ongoing condition (i.e. not a one-off event that lasts only two days). This can beundertaken by reviewing forecast conditions (based on information available on the BoM website, see Section6.4.3) to determine whether or not rainfall is anticipated and whether streamflows are expected to continue todecline. If reduced streamflow is anticipated for a period of greater than one week, then voluntary restrictions shallbe imposed.



The procedure for instituting voluntary restrictions is as follows:

Prepare a media release for issue to the press informing residents of the need to commence voluntaryrestrictions (not required by legislation, but should be undertaken as a best practice standard).

Advertise voluntary restrictions in the local newsletter and/or on local radio; Continue to monitor the situation. Review options to restore groundwater production capacity.

5.2.3 Introduction of Mandatory Stage 1

Stage 1 water restrictions are to be introduced in accordance with the storage levels listed in Table 1. The level ofrestriction adopted will depend upon the forecast for the immediate future. If the drought is expected to beongoing with very little rainfall, then Stage 2 restrictions should be adopted. If rainfall is predicted then it may bemore suitable to initially adopt Stage 1 restrictions.

The procedure for introducing Stage 1 water restrictions is as follows:

Prepare a media release for issue to the press informing the community of the introduction of therestrictions. This release must provide sound reasoning as to why that particular course of action has beenselected and must re-enforce the need to continue to conserve water.

Advertise restrictions in the local newsletter and/or on local radio. Commence formal discussions with DSE and local water carters to ensure that they are aware of the

situation. This would be a suitable time to discuss the availability of tankers with water carters and to lodgean application to access additional water in Betka River with DSE. The availability of a leased mobiledesalination plant could also be investigated.

Continue to monitor the situation.

At this stage it is critical for EGW to act quickly to minimise the need for introducing more severe waterrestrictions. Actions to be considered in addition to those listed above include:

An intensive advertising campaign using all forms of media so that consumers are fully aware of the detailsof this level of restriction. Leaflets mailed to consumers could be used to provide advice and information.Consumers should be made aware of the rules for each stage of restriction.

Implementation of Water Watch Days as a form of demand management.

5.2.4 Introduction of Mandatory Stage 2

Stage 2 water restrictions are to be introduced in accordance with the storage levels (specific to each month)listed in Table 1. Stage 2 restrictions are imposed if the drought is expected to be ongoing with very little rainfallprojected. In addition as an interim measure, it is recommended that if (i) the volume in the clear water storagedrops below 10 ML because of treatment plant capacity constraints and (ii) operational difficulties are expected topersist for several weeks, and (iii) no other viable ways of increasing treatment plant throughput are available,then Stage 2 restrictions should be implemented until the clear water storage recovers to a volume of 10 MLagain. This trigger is required to prevent the clay liner in the clear water basin from being stirred up and increasingin turbidity and/or the risk of algal bloom and is not a drought response measure. The air line should be turned onnightly if the clear water storage drops below 10 ML to reduce the risk of algal blooms.

The procedure for introducing Stage 2 water restrictions is as follows:

Prepare a media release for issue to the press informing the community of the introduction of therestrictions. This release must provide sound reasoning as to why that particular course of action has beenselected and must re-enforce the need to continue to conserve water.

Advertise restrictions in the local newsletter and/or on local radio. Continue to monitor the situation.



At this stage it is critical for EGW to act quickly to minimise the need for introducing more severe waterrestrictions. Actions to be considered in addition to those listed above include:

An intensive advertising campaign using all forms of media so that consumers are fully aware of the detailsof this level of restriction. Leaflets mailed to consumers could be used to provide advice and information.Consumers should be made aware of the rules for each stage of restriction.

Implementation of Water Watch Days as a form of demand management.

5.2.5 Mandatory Stage 3 Restrictions

Restrictions beyond Stage 2 should only be required on rare occasions of extreme emergency. Stage 3 waterrestrictions are to be introduced in accordance with the storage levels (specific to each month) listed in Table 1. Inthe event that the volume of storage drops below the specified restriction trigger level, EGW should instigateeither Stage 3 or 4 water restrictions, depending on the forecasts for the immediate future. If forecasts do notshow any relief to the dry conditions then Stage 4 restrictions should be selected.

The procedure to be undertaken for these levels of restriction include:

Introduction / continuance of a rigorous media campaign Make an application to the Victorian Government for full share of river flows in Betka River (in the event that

flows resume temporarily after previously having ceased) and for the use of water in deep pools on BetkaRiver.

If application(s) to the government granted and no other viable alternative supplies have been secured:- Obtain the necessary equipment to pump water from River.

5.2.6 Mandatory Stage 4 Restrictions

Stage 4 water restrictions are to be introduced in accordance with the storage levels (specific to each month)listed in Table 1. Stage 4 restrictions will only be required on rare occasions of extreme emergency. BeyondStage 3 efforts should be made to maintain base demands.

The procedure to be undertaken for these levels of restriction include:

Commence supply of alternative water from alternative emergency water sources including water carting,pumping from deep pools or desalination (see Section 7.3.4)



6.0 Pre Drought ActivitiesThis section of the DRP identifies a number of actions to be taken to ensure that the DRP can be implemented ina timely and efficient manner. These actions should be undertaken prior to the onset of drought to ensure thatEGW is adequately prepared.

6.1 Training and EducationIt is important for EGW to present an informed and consistent image to its customers. To this end all staff shouldat least be aware of the current status of restrictions, perhaps by reviewing updates on the EGW website.Customer service staff would require more detailed training on the specifics of restrictions. Drought educationshould be fostered on an ongoing basis. Training will also be needed for selected staff to be able to interpret thedrought warning signals. These signals will include information from various Bureau of Meteorology publications.Operators and staff will need to be aware of the system that will be operating in order to report information and theeffect that changing conditions will have on supply.

Relevant staff also need to be aware of the drought response procedure to ensure that the action plan can beimplemented successfully.

6.2 Community Education ProgramsEGW currently runs a number of community education programs aimed at reducing water consumption. Theseprograms include but are not limited to:

water efficiency awareness programs (showerhead rebates, information brochures etc); tours of schools to promote water efficiency in the home; targeted program for reducing water consumption in holiday accommodation during peak periods (including

the use of leaflets and posters); newsletters to account holders and stakeholders (‘On-Tap’ and ‘Pipelines’).

6.3 Promotion of Water RestrictionsUnder EGW’s Water Restriction By-Laws, the corporation is required to publish a notice in an appropriatenewspaper detailing the restrictions prior to their introduction. This requirement is only applicable for Stage 1 – 4restrictions with voluntary water restrictions being exempt.

In terms of advertising, EGW should treat all levels of restrictions (including voluntary restrictions) in a similarmanner. The following mediums are used for communication:

local newsletter (prepared on a weekly basis for the Lions Club); local Radio (3MGB); appropriate newspapers; and television commercials (as required)

Effective mediums for communication at Mallacoota have been the Local Newspaper and Radio. These methodsare to be adopted in the first instance with newspaper advertisements to also be used where mandatory waterrestrictions (Stage 1 – 4) are to be introduced. In some instances television advertisements may also beemployed as a means of communication (i.e. during extreme drought when Stage 3 or 4 water restrictions arebeing introduced).

In the early stages of drought or prior to peak summer periods, EGW should send an information pack toratepayers to reinforce methods for conserving water around the house.

Once mandatory restrictions are in place a toll-free phone number can be set up both to answer queries and toenable community policing of restrictions.



When initiating restrictions, it is important to promote messages about the nature of the problem, such as thefollowing:

low streamflows and depleting storage levels indicate a strong possibility that restrictions will need to beintroduced;public and private costs associated with the introduction of restrictions;inconvenience associated with restrictions;(by introducing voluntary reductions in water use at an early stage), the possibility of future restrictions beingrequired will be reduced.

The messages should point to the following specific uses of water that can reduce demand without significant lossof amenity, including:

use of waterwise practicesuse of water efficient appliancesreduction of obvious waste (e.g. pathway hosing, long showers etc)

6.4 Ongoing Monitoring and ReportingThe following section of the DRP sets out the monitoring and reporting requirements for the management of theMallacoota water supply system with respect to drought. A summary of actions to assist operators in trackingmonthly tasks is provided in Appendix B.

6.4.1 Regular Pre Drought Activities

The following regular activities are to be undertaken by EGW:

Calibration of the streamflow gauge (221218) at least annually Communication with DSE in relation to the status of water supply systems (monthly). Training and education of staff (ongoing as required). Monitoring of water supply situation as per Section 6.4.2 Monitoring of weather and drought forecasts on a monthly basis and more frequently during critical periods

(refer to Section 6.4.3). Communicate with the local community in relation to the status of the water supply system, particularly

during times when EGW is anticipating that restrictions may be required.

If the storages are below capacity due to maintenance works, the storages should be refilled whilst streamflowsare still available for diversion. Consideration should be given to deferring any works which will result in loss ofstorage capacity leading into a forecast drought period.

6.4.2 Water Supply System Monitoring and Reporting

EGW has comprehensive monitoring programs in place to collect data for the Mallacoota water supply system foroperational, reporting and planning purposes. A summary of the monitoring and reporting that should beundertaken by EGW is provided in Table 2.



Table 2: Summary of EGW Monitoring and Reporting Programs

Monitoring Monitoring Details Reporting Frequency and OutputBulk WaterDemand

Currently measured at outlet of theMallacoota Water Treatment Plant andon the groundwater bores.

Bulk water meter readings should be compiledby operators and provided to EGW’s managerof water supply systems

Surface water/potable water readings to beprovided on a weekly basis or more often ifstorages approach voluntary restriction levels.

Groundwater readings to be provided on aweekly basis during drought conditions andmonthly during non-drought conditions.

WaterStorageLevels

Water storage levels are provided onthe EGW website and are updated ona daily basis (as a minimum)

Operators should cross check storagelevels to ensure that automated datatransfer is correct

Water storage levels should be manuallymeasured and recorded by operations staff on aweekly basis. Discrepancies to be reported toEGW’s manager of water supply systems.

Water storage levels are to be reported back toEGW’s manager of water supply systems if thewater storage level drops below 90% capacity.

StreamflowMonitoringBetka River

Streamflow in the Betka River ismonitored by EGW using a data loggerto provide accurate real time flow data.

Operators should cross check this datato confirm logger is accuratelyrecording information

Streamflow data should be reported weeklywhen flows drop below 5ML/day.

Manually reads/estimates of streamflow to beundertaken on a weekly basis. Discrepancies tobe reported to EGW’s manager of water supplysystems.

Groundwaterproductioncapacity

Groundwater extraction and watertable levels are recorded by operators

Data should be recorded on a weekly basis andprovided to EGW’s manager of water supplysystems.

If production capacity is < 0.55ML/day, a reviewof the systems restriction trigger levels isrequired

Currently most monitoring is undertaken manually and reported weekly. It is recommended that EGW employ aremote monitoring and recording system such as a local Supervisory Control and Data Acquisition system(SCADA) for the Mallacoota water supply. By using SCADA to record river extraction, groundwater and storage,the burden for operating staff is reduced and reporting improved with the accessibility of timely information.

It is intended that the information gathered as part of the monitoring program will be entered into EGW’s ISESsystem, which will provide an overview of the water supply situation at any given point in time. Once ISES isoperational, annual auditing should be undertaken to ensure that it is receiving and using the correct inputs.

6.4.3 Climate and Drought Outlook

Climate monitoring should be undertaken so that when the indicators of drought start to emerge, EGW has time toprepare for the drought. The Bureau of Meteorology provides a number of services and publishes informationbooklets which have the potential to assist in the preparation for drought. These include the following publications:

Seasonal Climate Outlook - this provides three month forecasts of likely rainfall conditions expected over Australia(Provided by the BOM on a monthly basis at http://www.bom.gov.au/climate/ahead)

Drought Statement – this highlights areas of the continent experiencing significant rainfall deficiencies at standardintervals varying from 3 to 36 months prior to the release of the statement (Provided by the AustralianGovernment and reported on the BOM website http://www.bom.gov.au/climate/drought/drought.shtml)

Monthly Weather Review - this provides a detailed review of Victorian weather patterns for each month includinginformation on departures of temperature and rainfall from 'normal' (Produced by the BOM athttp://www.bom.gov.au/climate/mwr/)



Weekly Rainfall Report - this provides a more detailed review of weekly rainfall throughout Australia with furtherinformation provided on the impact of recent rains on deficits, and highest weekly totals for each state.(Providedby the BOM at http://www.bom.gov.au/climate/current/weeklyrain.shtml)

Rainfall Forecasts – provides maps of forecast rainfall for up to three months, with detailed five day forecasts alsoavailable. (Can be seen at http://www.bom.gov.au/watl/rainfall/exceedance.html)

The Bureau of Meteorology has a web site on the internet at http://www.bom.gov.au/climate, which has regularclimate updates and contact numbers for further information within the bureau.

There are a number of warning signs of drought that will be obvious at a very early stage. Rainfall deciles(expected rainfalls for various levels of probability) are also a useful indicator of drought severity. The Bureau ofMeteorology's Drought Statement is based on rainfall deciles. A drought is assumed to occur when the totalrainfall for a period of three months or more is in the first decile range (the lowest 10% of recorded rainfalls).When this occurs the area is considered to be suffering from a serious or severe rainfall deficiency and is includedin the Drought Statement. The Bureau of Meteorology has used the following definitions for serious and severedroughts:

a serious rainfall deficiency exists when the rainfall lies between the lowest 5% and 10% of recorded rainfallsfor the period in question;a severe rainfall deficiency exists for the period in question when the rainfall is among the lowest 5% of therecorded rainfalls.

Once an area has been classified as experiencing drought, it remains in its serious/severe rainfall deficiencycategory until:

the rainfall of the past month already amounts to above the 30th percentile for the three month periodcommencing that month; orrainfall for the past three months is above the 70th percentile for that period.

6.5 Funding Strategy for Drought ResponseDealing with drought will have impacts on the finances of EGW, as any form of reduction in demand will reducerevenue. Additional expenses are likely to be incurred as a result of drought and include the cost of publicrelations and media liaison, the cost of enforcing and policing restrictions, the cost of pumping fromsupplementary bores and the cost of water carting. EGW should ensure that its financial management strategywill enable it to overcome any short-term liquidity problems caused by drought.



7.0 Drought Response Options and Lifting of Restrictions

7.1 IntroductionDrought response options can be classified into the two broad categories of demand management and supplyenhancement. In this section of the report, the following potential demand management and supply enhancementoptions for EGW are identified and evaluated, including options for supply during extreme drought events:

Voluntary restrictions Water watch days Community Education Mandatory restrictions Water cartage Groundwater bores Increased share of river flow at low flows Access to River storage Desalination

The cost and viability of all drought supplies is dependent on a number of variables. These include proximity of anavailable source for carting, projected duration of water shortage, availability of tankers and desalination plant.

This action plan requires all options and variables to be considered in advance of Stage 4 restrictions so thatEGW continue to provide their service objectives or at least reduce the level of water restriction.

7.2 Demand Reduction OptionsThe main purpose of demand reduction options is to conserve the resources within the system, so that adequatebut reduced water supplies can be maintained for the duration of the drought. Restrictions will allow watersupplies to be shared equitably between competing users.

7.2.1 Voluntary Demand Reduction

The intention of Voluntary Demand Reductions is to make consumers aware that there is a possibility that WaterRestrictions will be imposed because of forecast shortages of water. They also act to raise heightened awarenessof the need to use water wisely.

Voluntary demand reduction should be promoted before any mandatory restrictions are imposed on thecommunity. As part of a voluntary demand reduction program, the following should be considered:

It is necessary to make people aware that the region is heading for a potential drought. Key indicators suchas a winter with low rainfall is a good starting point that local people can identify with. Forecasts of potentialdrought conditions can also be obtained from publications produced by the Bureau of Meteorology.Water conservation practices should be more heavily promoted than is done in normal years. The purposeof the campaign is to make people accustomed to the idea of impending restrictions and to reduceconsumption.This early campaign could be run by delivering educational leaflets to houses or by putting up specialnotices in prominent places such as local general stores. Other forms of media such as regionalnewspapers, radio or television could follow up the initial campaign if necessary. At this stage the aim of thepromotion campaign is to make people aware that a drought could be imminent and to encourage waterconservation on a voluntary basis. The experience of previous droughts could be highlighted.



7.2.2 Water Watch Days

EGW do not currently employ the use of ‘Water Watch Days’ although these could be used as a means to assistwith reducing water consumption on days when demand is at its peak.

Water Watch Days help make the community aware of the potential for more serious restrictions. These days areannounced when the temperature is forecast to exceed a specified maximum temperature (i.e. predictedtemperatures of 35 C or higher) and/or a day of total fire ban is declared. Consumers are requested not to usefixed sprinklers and automatic watering systems.

7.2.3 Demand Reduction due to Restrictions

Demand is heavily impacted by the implementation of a given restriction level. Restriction trigger levels are set inconsideration of:

the desired frequency of restrictions (defined by EGW’s Level of Service objectives); allowing sufficient time between restriction levels for community adjustment; and allowing sufficient time for EGW to arrange emergency supply arrangements in the rare event of reservoir

failure.

Refer to Table 1 for the restriction triggers set by EGW in Mallacoota’s 2006 DRP.

Clauses 4.2 and 4.5 of EGW’s Water Restriction By-Law state that:

“….. EGW must impose a stage of restriction in a district, whenever a restriction level trigger specified in itsdrought response plan or its by-laws is reached.……. EGW may decline to impose a stage of restriction in adistrict if it reasonably concludes that the circumstances indicating the need for that stage are likely to be sotemporary that the public inconvenience caused by imposing that stage of restriction would outweigh the waterconservation benefits to be gained from imposing that stage.”

EGW’s Water Restriction By-Laws outline the estimated monthly water savings associated with each level ofwater restrictions, as reductions in urban demand would be expected due to the implementation of the variousstages of mandatory water restrictions. A summary of the estimated annual reduction in total demand is providedin Table 3.Table 3: Reduction in total water demand for each level of restriction

Stage of Restriction Annual Reduction of Total Demand (%)

One 2.5Two 8Three 12Four 17.5

There will be a lead time associated with implementing mandatory restrictions, because restrictions need to beadvertised before they are enforced. Knowledge of storage volumes and demands throughout the drought willhelp to reduce this lead time to a few days.

Possible impacts of restrictions (at each stage) are as follows:

Restriction stage one is the least severe and can be classified as mild. Consumers would experience someinconvenience and perhaps minor losses such as lawn areas and plants.Restriction stage two could be classified as moderate. Implementation of this stage will create a moderatelevel of inconvenience to consumers and moderate losses will occur.Restriction stage three could be classified as severe. Implementation of this stage will create a majorinconvenience to consumers and substantial losses will occur.Restriction stage four is very severe and would only be implemented in very rare circumstances. This stagewould involve major disruption to normal lifestyles and would create major losses.Beyond the fourth stage of restriction an emergency situation would apply with consumers being in survivalmode. Only essential supplies would be available and there would be no irrigation or external watering.Urban consumers should however be restricted to no less than 60 litres per consumer per day, which is theminimum water requirement for basic human activity (UN, 1992).



7.3 Supply Enhancements during Drought7.3.1 Groundwater Reliability

If restriction levels are approached it will be due to a failure in the groundwater supply system. The reason for thisfailure should be investigated and options rectified as a first response. This could involve upgrading pumps,drilling a deeper bore or drilling an additional bore.

7.3.2 Water Carting

Water carting should only be considered as an emergency supply in the event that Mallacoota’s water storagesapproach critically low levels. An appropriate surface water or groundwater supply would need to be identified inthe event of a drought.

Carting surface water would either need to be sourced from Genoa (20 km), Wingan (45 km) or Cann River(72 km). Tankers were used on previous occasions to cart water from the Genoa rapids and from theWallagaraugh River near the Timbillica Bridge. Water from the Wingan River is often polluted by farm runoff andwould be less suitable as a temporary supply source.

Given that the Genoa River often ceases to flow during dry periods and Cann River is a significant distance fromMallacoota, identifying an alternative supply closer to Mallacoota would be advantageous. EGW is currentlyinvestigating the possibility of installing a groundwater bore at Gipsy Point, which could potentially be used foremergency supply to Mallacoota.

Approximately four trips per day would need to be made by a 15 kL tanker to supply 60 l/c/d to Mallacoota inwinter (1000 people). Significantly more trips would be required in summer to supply the higher population at thattime.

Should water carting be required, considerable forward planning would be needed to ensure suitable vehicles canbe secured and that water is available in nearby catchments. The lead time to arrange water carting is generallyless than one month, with tasks including considering the feasibility of loading and unloading water from thetrucks, locating an alternative water supply, obtaining water trucks and obtaining internal expenditure approval tohire the water carters. EGW should also consider paying water carters a retainer shortly prior to using them if theyare likely to be in high demand.

Lead times for water carting can be significantly reduced by gaining pre-approval and setting up arrangementsprior to the commencement of carting.

7.3.3 Qualification of Rights

Experience in the 1997/98 drought highlighted that river water quality can be poor if the river does flow during orat the end of drought. Therefore there are advantages in seeking a Ministerial qualification of rights to pumpcleaner water from river pools immediately prior to a runoff event in exchange for not pumping poorer qualitywater during the first flush of the river.

Pumping from the river would require approval from the Minister administering the Water Act. An application to theMinister would need to be made by EGW prior to the commencement of extraction from the river. The lead time toarrange for Ministerial Qualification of rights is around one month. EGW will need to keep a record ofmanagement of the drought to present to the Minister in writing.

The following options outline the points for accessing additional river flow. Due to the potential for environmentalimpact this option should be considered as a last resort.

1. Increased Share of River Flow

EGW may apply for a Ministerial qualification of rights to gain access to the environment’s share of the river flowat flows below 3.1 ML/d. Streamflow records suggest that the flow in the river recedes relatively quickly andceases to flow at the start of the drought when the town storages are full. There is not likely to be significantbenefit to EGW in obtaining these additional low flows at the expense of the environment and it should only beconsidered as an emergency option.

2. River Storage (Deep Pools) on the Betka River

During times of drought it may be possible to access additional surface water from deep pools on the Betka River.As discussed in the previous section, this option is not likely to provide significant benefit compared to the impactit will have on the environment. This option should only be considered as an emergency supply option.



The weir pool at the Mallacoota off-take was pumped during previous droughts. The volume available in this riverpool is unknown.

The Long Swamp pool can produce as much as 0.2 ML/wk if the creek is sandbagged at the road culvert. Thebags need to be ready to remove as soon as the drought breaks in case of minor flooding. In 2006 the fall in allcreek levels was so rapid that Long Swamp was not an option. This sudden drop in flow has not been observed inthese creeks before.

The crossing on the Betka River at Miner’s Track contains a pool of 5-10 ML of water behind a rock bar. A pumpor siphon could be used to transfer this water over the bar so that it could flow further downstream to the town off-take, 2km downstream. This could only be done every few days when the volume of water in the pool is largeenough. Practical investigations indicate that there are technical difficulties associated with pumping over the barand that it may not be feasible.

7.3.4 Desalination

A mobile desalination scheme may be suitable as an emergency supply option, if groundwater is no longeravailable and it is foreseen that water carting may be prolonged. When considering a desalination scheme as anemergency supply, a number of barriers are required to be overcome; including:

finding a suitable harvesting location; environmental impacts, such as salt intrusion, impacts of brine discharge; disposal of the brine waste stream; energy consumption – treatment of brackish and saline water using reverse osmosis is energy intensive; and acquiring regulatory approval - EGW currently has a brine discharge licence for the abalone co-op in

Mallacoota, it may be possible to utilise this existing discharge licence in order to facilitate the regulatoryprocess.

The following recommendations have been explained in order for EGW to include desalination as an emergencysupply option either; immediate and in the long term future to implement as their drought response plan.

1. Immediate

If emergency supply is necessary desalination could be an option if not required by another town. An option toconsider is the hire of a plant from a private operator. However, it is highly possible that a plant would not beavailable in a severe drought event.

2. Future

The 2009 WSDS suggested that a regional desalination plant may be viable to serve as an emergency supplysource for Mallacoota and other EGW towns. A small, mobile desalination plant could be purchased by EGW inorder to provide Mallacoota, as well as other towns in East Gippsland, during critical dry periods.

If a mobile desalination plant were to be purchased for the EGW region or rented then this DRP would be requiredto be updated accordingly.

7.4 Lifting of RestrictionsOccasionally there may be small rainfall events during drought which temporarily increase streamflow, allowingdiversions from the river and providing an increase in storage volumes. This increase in storage may result in thetriggers for a less severe level of restriction being reached. If this occurs, the level of restriction should only belowered if EGW is confident that the current level of restriction will not be reached again during the same drought.

For example, when Stage 4 restrictions are in place, an isolated summer storm may raise storage levels to justbelow the Stage 2 trigger. In this case, the level of restriction would only be lowered to Stage 2 if it is unlikely thatthe drought will persist and that the storages are not likely to reach the Stage 2 triggers again. This ensures thatcustomers are not confused by frequent raising and lowering of restrictions.



EGW’s Water Restriction By-Law states that:

“Subject to sub-clause 7.2, EGW may:

lift a prevailing stage of restriction and substitute a lesser stage of restriction; orlift a prevailing stage of restriction,

Whenever EGW reasonably concludes that the relevant circumstances which led EGW to impose the prevailingstage of restriction in a district no longer exist, or are about to change, by publishing a notice in a newspapercirculating generally in that district.

EGW may also decline to lift a prevailing stage of restriction if it reasonably concludes that either:

continuing that stage of restriction is necessary or desirable to increase or conserve available water; orthe change in circumstances which would otherwise justify EGW in lifting the stage of restriction is likely tobe so temporary that the public inconvenience caused by lifting and subsequently re-imposing a stage ofrestriction would outweigh the benefits to EGW's customers of temporarily lifting the prevailing stage ofrestriction.

The lifting of restrictions should occur when groundwater production capacity has been restored to a level whichallows supply to meet demand or alternatively when storage levels have remained above the trigger level for aperiod of 7 consecutive days.



8.0 Post Drought Activities

8.1 Evaluation of ObjectivesOnce the drought has broken and a degree of order and normality has returned, it is time to review theeffectiveness of the plan. The first part of the review process should be to assess the suitability of the objectives.There are three components to the objectives (i.e. strategic, planning and operational) and each of these needs tobe critically reviewed to determine whether the objectives were appropriate and achievable. If they were not,some comment needs to be made as to why not and new objectives set for the next drought.

8.2 Evaluation of ActionsThere have been a number of actions identified for demand reduction and supply augmentation as the supplysituation worsens. In most droughts, only a few of the actions will need to be implemented. The timing andeffectiveness of each action needs to be assessed and documented. If, for example, the introduction of Stage 2restrictions leads to a greater reduction in demand than anticipated then a decision needs to be made as towhether this restriction is too severe or whether it should be implemented at a later date when more seriousconditions have developed. Alternatively, the appropriateness of the restriction policy and the actions tied to eachrestriction stage should be evaluated and modified where necessary.

Comparisons between historic deliveries and drought deliveries will have been made as part of the monitoringprocess during the drought. These need to be documented as part of the post-drought evaluation, and commentsand decisions made about the impact of each stage of restriction during a drought.

8.3 Potential Impacts of RestrictionsPotential impacts from shortfalls in supply, based on previous drought experience in various catchments, includethe following (SKM, 1997):

Loss of amenity for the community due to the deterioration of plants, gardens and sporting fields.Financial loss to the community, incurred when regaining the level of amenity desired during non-droughtperiods.Inconvenience on the community caused by forcing users to alter their water-use practices.Financial loss to tourist-based local economies, as a result of holiday makers wanting to avoid theaforementioned loss of amenity and convenience.Stresses on in-stream flora and fauna.Reductions in revenue for water corporations caused by restrictions on consumption.Increased expenses for water corporations for promoting and enforcing restrictions, and for providingemergency supplies.

Concern about the effect of restrictions on tourism and hence employment was noted in the previous DRP (2006):

Whilst there was no specific note of this in the 1998 drought, these activities should be monitored in futuredroughts. In general, restrictions will tend to have a minimal effect on tourism numbers in the Christmas/New Yearperiod because accommodation is pre-booked. Severe restrictions at Easter may potentially affect touristnumbers, however current experience shows that Mallacoota experiences restrictions as frequently or less oftenthan many other towns in Southern New South Wales and East Gippsland. Hence, Mallacoota is unlikely to beuniquely avoided as a tourist destination in the region because of water restrictions.



8.3.1 Impact of Restrictions on the Community

Community response to the imposition of restrictions should be sought through contact with representatives of themajor water user groups. Questions which should be asked in the wake of a drought by EGW, both of itself andconsumers, include:

Were there other things that could have been done to help reduce demand for water?What were the economic and social impacts of restrictions?Was there enough warning that restrictions were to be imposed?Was the right mix of media used to disseminate information on when the restrictions were to begin and whatwas and was not allowed to be done?Were the restrictions too severe?Did restrictions last too long?Were people confused by the number of restrictions?What attitude did people have during the drought?Was there any significant plant loss?Was there any major inconvenience caused by the lower stages of restrictions?

8.3.2 Impact on East Gippsland Water

The Corporation’s actions should also be reviewed to determine how it coped with the additional burden ofdrought. In particular, it will be important to identify any issues that came up that were not identified prior to thedrought and were not taken into account in the Drought Response Plan, such as:

Were the restrictions easy to enforce?Were the limited watering times causing problems for supervision?Did the staff feel alienated from the community?Was the additional work load unreasonable?Do staff have any suggestions for improvements for the Drought Response Plan?

8.4 Revision of the DRPDrought Response Plans are dynamic in nature and will only be appropriate for a particular system for a shortperiod of time. Drought Response Plans need constant revision to keep them up-to-date with changes in climate,system configurations, demand, operational procedures, community expectations, diversion rules etc. Therevisions should be based on the results of the evaluations referred to above and carried out in a regular anddisciplined manner.

It is recommended that this drought response plan be reviewed on an annual basis and updated every five yearsas a minimum. Specific aspects of the plan should be updated as required after major changes to the supplysystem such as the construction of new storages and/or changes to diversion rules. If modification of the plan isrequired in a drought event or if particular lessons are learnt during a drought, EGW should update the planaccordingly prior to the next summer period.



9.0 Water Supply Context

9.1 Legal and Institutional Context9.1.1 Bulk Water Entitlements

Section 9 of the Water Act (1989) specifies a water corporation’s right to take amounts of water that are madeavailable to it either:

a) under a bulk entitlement granted under that Division or part 11; or

b) under any entitlement to take water granted under and corresponding previous enactment and continuedby this Act.

EGW has a bulk water entitlement of 330 ML per year for the Betka River. EGW can take up to 1.55 ML per daywhen flow in the river exceeds 3.1 ML per day or 50% of the flow at other times.

9.1.2 Applying for Qualifications to Bulk Entitlements

EGW may apply to the Minister to qualify its bulk water entitlement during water shortages. The qualification mayinclude allowance to pump from river pools or to divert greater flow volumes. Such an application would be madeunder Section 33 of the Water Act (1989). The qualification would only be granted where the Minister hasdeclared under Section 13 of the Act that a water shortage exists in the area or supply system and EGW hasmade reasonable efforts to prevent this water shortage.

This has been included as a drought response option in Section 7.3.3.

9.1.3 Groundwater Entitlements/Licences

EGW currently holds a licence (licence number 9016496) to extract a total of 80 ML of groundwater each year tosupplement Mallacoota’s water supply during times of low flow in the Betka River.

In August 2008 GHD prepared a hydrogeological assessment for EGW to support an application to access afurther 40 ML each year. EGW must comply with a number of conditions, including the submission of agroundwater monitoring program, which provides data for the assessment of potential impacts to surface waterfeatures (such as rivers, wetlands and/or groundwater dependant ecosystems) and to the aquifer through salinewater intrusion, before Southern Rural Water (SRW) will allow access to the additional water. It is understood thatEGW are currently implementing a groundwater monitoring program and investigating locations for additionalmonitoring and production bores.

A review of the last three years of bore level data indicates that 120 ML/year of extraction is likely to be within thesustainable yield of the aquifer. This is consistent with the findings of the 2008 GHD report. The GHD report alsoconcluded that the existing bores have the capacity to supply 120 ML per year to Mallacoota; however there issome evidence to suggest that the supply can be affected during peak periods if adequate recharge time isn’tallowed.

9.1.4 Supply to Urban Users

Under the terms of the Water Act (1989), a Corporation does not have to meet any stated volume, capacity orpressure requirement within a water pipeline supplying urban consumers.

In addition, under Section 141 of the Water Act (1989), a Corporation may reduce or restrict the quantity of watersupplied to any person, or discontinue the supply of water to any person, if:

a) the Corporation is, because of a shortage of water or for any other unavoidable cause, unable to supplythe quantity of water which would otherwise be supplied to the person; or

b) the Corporation believes that the reduction, restriction or discontinuance is necessary to avoid futurewater shortages.

These sections give adequate powers to EGW to restrict water quantities in times of drought in accordance withby-laws proclaimed under Section 171 of the Act.



9.1.5 Model Water Restriction By-Law (No. 001/08)

During May of 2008, the Water Minister issued EGW’s ‘Model Water Restriction By-Law’ under section 287ZB ofthe Water Act (1989). The intent of the By-Law is to:

Promote the conservation of water; Set out four stages of restrictions on the use of water; Specify when and how a stage of restriction may be imposed Specify things which must not be done while each stage of restriction persists Specify principles for considering applications for exemptions from particular restrictions Specify principles for deciding when to lift restrictions; Prescribe offences and penalties for the contravention of the By-law Prescribe classes of persons for the purpose of issuing infringement notices.

A copy of this By-Law is attached in Appendix C.

9.1.6 Drought Reporting

The communication of the status of each supply system leading into, during and following drought conditionsforms an integral part of drought response planning. EGW prepares a monthly summary report for the Departmentof Sustainability and Environment (DSE) that provides an overview of the status of each of EGW’s water supplysystems. The report details current storage levels, water restrictions and future rainfall projections (wherenecessary) and identifies any potential water supply issues. This allows the Water Minister to remain informed onthe current water supply situation. In critical times of drought, the frequency of communications between EGWand DSE should increase in accordance with the severity of the situation.

EGW’s Water Restriction By-laws require that when introducing water restrictions, as a minimum, EGW mustpublish a notice in a newspaper that circulates generally within that district. Generally EGW will undertakeadditional advertising through the use of local radio and publications, although this is not required under currentinstitutional arrangements.

Under EGW’s Customer Charter they also have a responsibility to provide information to customers about thesustainable use of Victoria’s water resources and how customers may conserve water.

9.2 Levels of ServiceThe long term operational objective for East Gippsland Water stated that it should be aware of changes to totallevels of service and patterns of demand, and of consumer expectations in relation to desirable levels of service.Regular updates, perhaps every three years, in relation to growth in the number of services provided needs to bemaintained and interpreted in terms of actual and 'acceptable' levels of service.

EGW has previously defined the following level of service objectives for water supply reliability:

Moderate restrictions (Stages 1 & 2) are not desired more frequently on average than 1 year in 10More severe restrictions (Stages 3 & 4) are not desired more frequently than 1 year in 15.

The WSDS determined that the trigger levels presented in Table 1 are appropriate for maintaining these level ofservice objectives.



10.0 Past Drought Experience

10.1 Previous DroughtIn the past, difficulty has been experienced in supplying water to Mallacoota during summer. Restrictions wereimposed in 1982/83, 1987/88 and more recently in 1997/98. Each drought event and the lessons learnt arediscussed below.

Mallacoota has not experienced water restrictions in recent years.

10.1.1 The 1982/83 Drought

A summary of this event is shown in Table 4.

Remedial works were carried out on Reservoir No.2 (capacity 41 ML) in October 1982 and it did not refill in timefor the 1982/83 drought. In addition, the two groundwater bores being drilled for drought relief were not completedbefore the drought ended and were not available to use.

10.1.2 The 1987/88 Drought

A summary of this event is shown in Table 5.

This drought was not as severe as the 1982/83 event and both storages were full at the onset of drought.Restrictions were eased to Stage 2 in early February and then raised again to Stage 3 on February 20th. Stage3A restrictions are identical to Stage 4 restrictions, but appear to have been renamed when they were introduced.

10.1.3 The 1997/98 Drought

A summary of this event is shown in Table 6. The drought was effectively managed and supply was maintainedthroughout. The key lessons learnt were as follows:

Early monitoring for drought ensured storages were filled at the onset of drought.The groundwater bore was successful in providing an alternative source of supply, but yield decreasedtowards the end of the drought. This bore was replaced with two new bores in 2000 that appear to be higheryielding.A small volume of water must be maintained in the raw water storage to aerate the groundwater, becauseiron levels are too high to pump directly into the treatment plant.River water quality can be poor if the river does flow during or at the end of the drought. If Ministerialapproval is obtained, pumping from the river pool immediately prior to rainfall can help to capture cleanerwater whilst letting more turbid water pass. This can help to bring a swifter end to restrictions.

When communicating with its customers, EGW learnt that:

If a trigger level is being approached, restrictions should be put in place on or before a public holiday periodwhen demand increases.Changing the colour or heading on restriction notices for different stages of restriction highlights the change.Local radio broadcasting at Stage 4 was very successful.There were complaints about people washing boats in contravention of the restriction by-law. This wouldappear to require specific promotion in Mallacoota.

11.0 Summary of RecommendationsThe following recommendations are made to EGW in order to assist with the implementation of this DRP:

Implement monitoring and reporting programs as described in Section 6.4. In particular, evaluate theinstallation of SCADA and associated monitoring devices within the Mallacoota water supply system.

Review and complete the pre-drought activities outlined in Section 6.0 and adopt the Action Plan in Section5.0 for responding to drought situations.

WATER RESTRICTION BY-LAW

East Gippsland Water makes the following By-law:

1. AUTHORISING PROVISIONS

This By-law is made under sections 160, 171(1)(a), (ba), (bb), (bc), (e) and (j) and 287ZC of the Act.

2. PURPOSES

The purposes of this By-law are to:

(a) promote the conservation of water; and

(b) set out four stages of restrictions on the use of water; and

(c) specify when and how a stage of restriction may be imposed; and

(d) specify things which must not be done while each stage of restriction persists; and

(e) specify principles for considering applications for exemptions from particular restrictions; and

(f) specify principles for deciding when to lift restrictions; and

(g) prescribe offences and penalties for the contravention of this By-law; and

(h) prescribe classes of persons for the purpose of issuing infringement notices.

3. DEFINITIONS

"application for exemption" means an application made under paragraph 6.1(a).

"authorised person" means a person authorised in writing by East Gippsland Water for the purposes of undertaking the functions referred to in paragraph 6.1(c).

2.

4. STAGES OF RESTRICTION

4.1 Subject to sub-clause 4.5, East Gippsland Water may impose:

Stage 1 (Mild) Restrictions; or Stage 2 (Medium) Restrictions; or Stage 3 (High) Restrictions; or Stage 4 (Critical) Restrictions,

as the case requires, in any district of the water corporation, by publishing a notice in a newspaper circulating generally in that district.

4.2 Subject to sub-clause 4.5, East Gippsland Water must impose a stage of restriction in a district, whenever a restriction level trigger specified in its drought response plan or its by-laws is reached.

4.3 Despite sub-clause 4.2, East Gippsland Water may also impose a stage of restriction in a district, if it reasonably concludes that:

(a) because of the failure of a major pipeline, pumping station, treatment plant or other key water supply work, East Gippsland Water will temporarily be unable to meet the demands of its customers; or

(b) an existing stage of restriction has failed to provide the combined estimated savings for the relevant stage, as set out in Schedule 1; or

(c) a stage or higher stage of restriction should be introduced to conserve water available to a district.

4.4 When a stage of restriction is imposed in a district under sub-clause 4.2 or 4.3, the relevant restrictions on water use designated for that stage in Schedule 2 apply in that district.

4.5 Despite sub-clause 4.2, East Gippsland Water may decline to impose a stage of restriction in a district if it reasonably concludes that the circumstances indicating the need for that stage are likely to be so temporary that the public inconvenience caused by imposing that stage of restriction would outweigh the water conservation benefits to be gained from imposing that stage.

5. SUSPENDING RESTRICTIONS

5.1 Despite sub-clause 4.4 and subject to sub-clause 5.2, East Gippsland Water may, from time to time during any stage of restriction in a district, wholly or partially suspend, or vary the prescribed hours of, the operation of any restriction on water use designated for that stage in Schedule 2:

(a) in relation to such class of use or users; and

(b) in such manner; and

(c) subject to such conditions; and

(d) for such period,

within that district as East Gippsland Water may specify, by publishing a notice in a newspaper circulating generally in that district.

3.

5.2 In deciding whether or not wholly or partially to suspend, or vary the prescribed hours of, the

operation of a restriction under sub-clause 5.1, East Gippsland Water will have regard to:

(a) recent climate patterns and prevailing seasonal forecasts; and

(b) any anticipated change in demand attributable to the prevailing stage of restriction; and

(c) any other relevant matter which East Gippsland Water thinks fit to have regard to.

6. EXEMPTION FROM RESTRICTIONS

6.1 Applications for Exemptions

(a) A person may apply to East Gippsland Water for an exemption from a stage of restriction which has been, or which may in future be, imposed under sub-clause 4.1.

(b) An application for exemption must be in a form approved by East Gippsland Water.

(c) An authorised person:

(i) must consider an application for exemption; and

(ii) subject to this clause, either before or after the relevant stage of restriction has been imposed:

• may grant the application in full or in part and subject to such conditions as the authorised person considers appropriate; or

• may refuse the application; and

(iii) may revoke any exemption at any time, by giving written notice to the applicant.

(d) An exemption ends at any time specified in the exemption, or when:

(i) the stage of restriction to which the exemption relates is lifted; or

(ii) a more severe stage of restriction is imposed.

6.2 General rules about exemptions

An authorised person must not grant an application for exemption in relation to a particular stage of restriction, unless the authorised person is reasonably satisfied that the proposed exemption EITHER:

(a) is necessary to avoid an inequitable and disproportionately adverse impact upon the livelihood of the applicant which would be caused by the level of restriction; OR

(b) would result in less water being used by the applicant than the lesser amount of the water that the applicant would otherwise;

(i) have been allowed by East Gippsland Water to use; or

(ii) based on prior consumption, is likely to have used for the same purpose under that stage of restriction; OR

4.

(c) is necessary because of the special needs of the applicant; AND would merely alter the hours

between which water may be used by the applicant, BUT would not increase the total number of hours in any day for which water may be used by the applicant under that stage of restriction; OR

(d) would avoid or minimise appreciable physical damage to a building or other structure owned or occupied by the applicant during that stage of restriction; OR

(e) is necessary to avoid any adverse effect on public health or safety;

AND

(f) would not, in combination with other comparable applications reasonably anticipated by East Gippsland Water, have a significant impact upon the total daily demand for water by East Gippsland Water's customers in the relevant area where the use will occur during that stage of restriction; AND

(g) is likely to be generally supported by other East Gippsland Water customers who are affected by that stage of restriction.

6.3 Exemptions for gardens open to the public

Despite sub-clause 6.2, an authorised person may grant an application for exemption with respect to a garden which is either usually or periodically open to the public (whether or not a fee is payable) if:

(a) the application is accompanied by a water conservation plan for the garden; and

(b) the water conservation plan has previously been approved by East Gippsland Water; and

(c) the authorised person is reasonably satisfied that, if the garden is watered in accordance with the water conservation plan, the proportion of water saved in watering the garden will be no less than any proportion set out in Schedule 1 for a relevant month under a relevant stage of restriction.

6.4 Exemptions for certain playing surfaces

Despite sub-clause 6.2, an authorised person must not grant an application for exemption during a period of restriction to water any playing surface (including an exempt playing surface, as defined in Schedule 2) unless the application:

(a) relates to a surface which is to be used for an inter-State, national or international professional sporting competition, the dates for which were scheduled before the relevant stage of restriction was declared; and

(b) is granted for a finite period, which includes the dates during which the competition is to be held, determined after consulting the applicant.

6.5 Exemptions for water tankers

Despite sub-clause 6.2, an authorised person must not grant an application for exemption to fill a water tanker, as defined by Schedule 2, during any period of restriction, unless:

5.

(a) the application relates to water to be used to hand-water trees by means of a hose fitted with

a trigger nozzle; and

(b) the exemption is subject to the condition that the water tanker must only be filled between 8 am and 8 pm.

7. LIFTING A STAGE OF RESTRICTION

7.1 Subject to sub-clause 7.2, East Gippsland Water may:

(a) lift a prevailing stage of restriction and substitute a lesser stage of restriction; or

(b) lift a prevailing stage of restriction,

whenever East Gippsland Water reasonably concludes that the relevant circumstances which led East Gippsland Water to impose the prevailing stage of restriction in a district no longer exist, or are about to change, by publishing a notice in a newspaper circulating generally in that district.

7.2 Despite sub-clause 7.1, East Gippsland Water may decline to lift a prevailing stage of restriction if it reasonably concludes that either:

(a) continuing that stage of restriction is necessary or desirable to increase or conserve available water; or

(b) the change in circumstances which would otherwise justify East Gippsland Water in lifting the stage of restriction is likely to be so temporary that the public inconvenience caused by lifting and subsequently re-imposing a stage of restriction would outweigh the benefits to East Gippsland Water's customers of temporarily lifting the prevailing stage of restriction.

8. CONTRAVENTIONS OF THIS BY-LAW

8.1 A person who receives a supply of water from East Gippsland Water in a period when stage 1 restrictions imposed by or under this By-law are in force must not contravene any such restriction on the use of that water.

Penalty: For a first offence, 40 penalty units or 3 months’ imprisonment;

For a second or subsequent offence, 80 penalty units or 6 months’ imprisonment.

Notes:

1. In this By-law “penalty unit” has the same meaning as in section 110 of the Sentencing Act 1991. The value of a penalty unit increases each year under the Monetary Units Act 2004. The current value of each penalty for contravening a restriction is set out on East Gippsland Water’s website www.egwater.vic.gov.au.

2. The Act also makes it an offence to waste, misuse or excessively consume water and imposes substantial penalties which include one or more of fines, imprisonment and daily penalties.

3. East Gippsland Water has further power to reduce or restrict the supply of water to a person who contravenes the Act or regulations in relation to misuse of, or taking water. East Gippsland Water can also disconnect the services to a property in relation to which a notice of contravention has been issued and not complied with.

9. POWER TO SERVE AN INFRINGEMENT NOTICE

9.1 An authorised water officer appointed under section 291A of the Act by East Gippsland Water may serve an infringement notice on another person in respect of an offence against clause 8 if the authorised water officer reasonably believes that the person has committed the offence.

9.2 For the purposes of this clause, the infringement penalty for an offence against a sub-clause set out in Column 1 of the Table is the relevant amount set out in Column 2 of the Table in respect of that offence.

9.3 A summary of an offence in Column 3 of the Table is not to be taken to affect the nature of elements of the offence to which the summary refers.
