CITY OF ROSSLAND Annual Water Report - 2020

Introduction

T he City of Rossland provides drinking water to users connected to the Rossland Water System. This report is provided to City Council for their information, and in fulfillment of the City's obligations under the Provincial Drinking Water Act and associated regulations, as well as the terms and conditions of the City's Water System Operating Permit. Enforcement of the regulations and issuance of water system permits is the responsibility of the Interior Health Authority's Drinking Water Officer.

Raw Water T he City's raw water source is entirely surface

water in three alpine creek catchments: Topping Creek, Hanna Creek and Murphy Creek, with intakes adjacent to Highway 3B between Red Mountain and Nancy Greene Summit, ranging in elevation from 1200m to 1550m above sea level. A map of the ate rs he d locations is provided in Appendix A.

The City sampled and undertook complete testing of Star Gulch and Ophir raw water reservoirs in 2020 and the result of these tests is provided in Appendix 8.

CITY OF

ROSSLAND

Raw water is collected at Hanna and Murphy Creek intakes and transmitted by pipeline ranging in size from 150mm to 250mm to Ophir Reservoir which has a capacity of approximately 165,000 cubic meters. Ophir Reservoir water is piped to Star Gulch Reservoir along with raw water from Topping . Creek intake to fill approximately 120,000 cubic meters. During the Spring/Fall Freshet, all three creeks, and the reservoir, overflow water for many months as supply exceeds consumption.

The City of Rossland inspects intakes, pipes and areas immediately around the intakes on a monthly basis in summer, while winter and spring access limits inspections to a couple of times by snowshoe, snowmobile or e-bike. Much of the watershed is used for recreation, with skiing, mountain biking, horse riding and hiking activities common. The City has erected signage near facilities and along hiking trails indicating that the area is part of the City's watershed.

Water Main Flushing The City flushes the water mains annually as a health requirement during the month of May to help maintain water quality with our aging infrastructure by removing scale and sediment in the pipes. When required, the City will flush specific areas around town where there are minimal flows .

Valve Replacement The City has an ongoing program to replace aging valves in the water distribution system for better control of directional flushing as well as less disruption when a water repair is required.

City of Rossland Annual Water Report - 2020

Treated Water J mmediately south of the Star Gulch Reservoir 1s the City's Water Treatment Plant located adjacent to Highway 3B. This facility was built in 1996 and is comprised of three main buildings - two slow sand filter buildings and one control and pumping building. There are six slow sand filter bays drawing water directly from Star Gulch Reservoir. These bays are monitored

daily and periodic maintenance includes the removal of build up on the surface of the Smutzdecke (active biological layer). Water passes through the filter bays and is then chlorinated using chlorine gas before being stored in the clearwater tank prior to distribution to the City.

repair work as required. A stock of extra parts and equipment, as well as quick-connect plumbing and electrical connections ensure complete redundancy of the system at all times, to minimize the chance of extended breakdowns.

Distribution System

The City's distribution system is comprised of a variety of pipe materials, from ductile iron

cement lined, mild steel, asbestos cement, copper, PVC and Polyethlyne. Replacement of older pipe materials is a slow process, and as

opportunities arise through subdivision, building permits, paving work or detected leaks, the City is replacing pipes and service

contributing to lower consumption rates in the base area. This storage also provides backup supply for the remainder of the City in the event of a power failure or other issues with the treatment plant.

Upper Rossland Zone The Upper Rossland Zone is fed by gravity from the Treatment Plant. This zone essentially services properties at elevations at and above the downtown core.

Kirkup Zone The Kirkup zone is supplied from a small pump station at the intersection of Kirkup Ave and Plewman Way which is in the Upper Rossland Zone. Water is pumped to a bolted steel reservoir located on Mount Kirkup and feeds residential properties that are located above the minimum pressure zone provided by gravity from the treatment plant.

Lower Rossland Zone Two Pressure Reducing Valve (PRV) stations separate the upper and lower Rossland Zones. These are located outside 1 8 9 9 Columbia A venue, and on Park Street above the Pinewood subdivision. This zone encounters operational challenges with older infrastructure and low flows in some sections.

Redstone Zone With the completion of the first phase of the Redstone subdivision, residential water services were provided to this area. A PRV station along Esling Drive reduces the pressure from over 230 psi to around 20 psi to ensure that pressures within the subdivision do not exceed 150 psi.

Star Gulch Reservoir

Water Sampling & Testing Program

Drinking water delivered to users of !he City system is subject to a comprehensive and rigorous testing program that ensures quality drinking water. Continuous monitoring of free chlorine residual readings, temperature, turbidity & pH in the drinking water is accomplished with Hach meters located in the Water Treatment plant (disinfection takes place here). On a daily basis City staff test samples of drinking water from the plant. On a weekly basis City Staff test separate locations for free chlorine residuals (i.e. the presence of chlorine in the water). These tests are conducted with hand-held Hach meters that measure the minute amounts of disinfectant that must be in the drinking water throughout the system to meet regulations. Sample points are located at the start, middle and end of the entire City water distribution system to ensure the effectiveness of the disinfection program. At least 0.2 ppm (mg/ L) of chlorine must be present in every litre of water to meet these standards. There was five to six hundred manual chlorine residual tests conducted by City staff in 2020 over 10 various locations around town. The WTP values going out of the plant and into he treated water reservoirs are 0.57 ppm-1.01 ppm with an average of 0.83ppm. The Distribution System values are 0.19ppm-0.78ppm with an average of 0.41 ppm. Whenever staff determine the readings may be trending too low they slightly increase the dosage of disinfectant at the Water Treatment P 1 ant and confirm the results during the next day's tests indicating residual levels have increased. Water samples are sent, on a weekly basis to the Passmore Laboratory ( or Caro Environmental Services for special tests) to be tested for the presence/absence e-coli and total coliform bacteria. City staff take these samples and sends them to the labs and results are returned to the City within a week.

CnYOf.fl City of Ross land Annual Water Report - 2020

ROSSLAND

The standard protocol when a water sample is found to contain the presence of coliforms, however minute, is to resample the water immediately at the same location and resubmit for testing. The provincial Drinking Water Officer will determine if any action by the purveyor is necessary only after a second test also shows the presence of coliforms.

In 2020, the City submitted approximately 100 samples for ecoli and coliform testing.

Turbidity is monitored continuously after filtration with the highest reading at 0.103 NTU and the lowest reading of 0.072 NTUand an average reading of0.076 NIU during 2020.

See Appendix C for bacteria test results

Records The City uses SCADA (System Control and Data Acquisition) to continuously monitor water quality, flow, pressure and storage. This system assists City staff to maintain a safe drinking water supply by advising when dosage or residual disinfectant levels are outside of set parameters ( either high or low) for the system. The SCADA system will alert staff by cell phone to ensure that corrections can be made before water quality can be adversely affected.

This data is stored at the Water Treatment plant. This data is forwarded on a monthly basis and is used to provide information to the provincial Drinking Water Officer, including the completion of this annual report. Flow records are taken daily to determine the volume of treated water being produced and distributed. Future upgrades of this system would include the installation of further flow meters for raw water and treated water at key points m the distribution system.

Water Consumption

W ater consumption in 2020 was less than the previous year. The total water

consumption was 680,380 cubic meters as compared to 750,955 cubic meters in 2019. Since we started the metering program in 2009, there has been up to a 30% decrease in water usage over the years. See Appendix D Consumption Report

Consumption at Red Mountain is able to be measured separately as all of the water for this zone is pumped and passes through a flow meter. Typically, the consumption at Red Mountain is lower per unit than in the rest of the City, this is a function of less irrigated landscaping per lot, and lower occupancy levels in the summer. Minimum daily demands are fairly constant in town throughout the year, ranging between 1 , 1 6 9 - 2 , 1 1 5 cubic meters per day. Maximum day demands occur during summer (June-September) and range approximately from 1,509-3,570 cubic meters for irrigation periods.

New Connections In 2020, the City received 26 building applications for new dwellings (residential only) which is down from 27 in 2019.

Regulatory and Administration

Water Metering and Conservation Program Water meters are currently enforced in new development through the building permits and must be installed before occupancy. There were 1823 water connections in early 2020 and 1803 of those were metered. By the end of 2020 there were 185 5 total connections and 1840 were metered.

Emergency Response Plan and Dam Management

In 2016, as part of the review of the emergency preparedness, the City worked with Engineers and started a formal geotechnical assessment of Star Gulch reservoir and submitted the Emergency Preparedness Plan and the Operation, Maintenance and Surveillance Plan for Star Gulch Dam to the Ministry. The City completed the dam safety review on Star Gulch in 2016 and the OMS and EPP for Ophir Reservoir. Currently the City is working with the regional dam safety officer to complete the Star Gulch OMS and EPP.

Staffing Trained, certified City staff work to maintain the 24 hour per day supply of safe drinking water to users in Rossland. This is accomplished by ensuring that staff is on call every day of the year and that the previously mentioned surveillance, operating and control system (SCADA)is operating continuously. Water distribution work is also done by staff certified for their tasks: water main replacement, water service installation, fire hydrant and valve maintenance. Special tasks such as reservoir cleaning and leak detection are undertaken by qualified staff with the proper equipment, training and experience to complete the work.

The City has two Level 1 Water Treatment Operators and one operator with Level l& 2. The City has two Water Distribution Level 1 operators and one Water Distribution Level 1& 2 operator, and two operators trained in Chlorine Handling.

Capital Expenditures In 2020, The City ofRossland received grants and capital funds that will allow the removal of chlorine gas from the plant and upgrade to a hypochlorination system. This will reduce the risks of exposure related to chlorine gas by eliminating the source. We will also be adding a soda ash injection system to increase alkalinity and pH levels and upgrade the SCADA system. This project started in 2020 and will be completed in 2021.

Conclusion This 2020 City of Rossland Water System Report is presented to the public, by way of posting on the City of Rossland website, as required by the British Columbia Drinking Water Protection Act and Regulations, as well as to meet the terms and conditions of the City's Water System Operating Permit CITYRO 950 issued by the Interior Health Drinking Water Officer.
