f. Legal Authorities and Controls

1. Sewer Rules and Regulations

Coplay-Whitehall Sewer Authority has established and implemented regulations regarding the

use of the wastewater collection system. The Authority has a comprehensive set of Rules and

Regulations, adopted by resolution, and complimentary to the standards required by the City of

Allentown’s wastewater treatment plant. As regulations and requirements have changed, the

Authority has passed additional resolutions to address those issues. The Rules and Regulations

are kept up-to-date and are available electronically at the Authority’s website.

The items addressed through the Rules and Regulations include: sewer use and standards, access

to pipelines and structures, service connections, user rates, permitting of flows into the system,

inflow/infiltration control, enforcement of proper design, installation, and testing standards, and

inspection requirements for new and rehabilitated sewers. The Finance Committee, the Authority

Manager, and the Authority Board review the adequacy of user rates annually.

2. Joint Sewer System Agreement

The CWSA has entered into Inter-Municipal Agreements with neighboring South Whitehall

Township (SWT) and North Whitehall Township (NWT), which provide for the connection to

CWSA’s system for conveyance of effluent originating from sections of each of these Townships

through the CWSA system for treatment at the KIWWTP. SWT and NWT each have (2)

connections to the CWSA System. SWT connects to the CWSA system at SWT’s Jonathan and

Quail Metering Stations and then utilize CWSA’s Jordan Creek Interceptor. NWT connects to

the CWSA System at the Quarry and Omrod Metering Stations and then discharge to CWSA’s

Coplay Creek Interceptor

Coplay-Whitehall Sewer Authority has had an agreement with the City of Allentown for

treatment of its wastewater since the 1960’s. The latest agreement is dated 1981. Coplay-

Whitehall Sewer Authority has purchased capacity rights for 3.76 million gallons per day of

wastewater treatment.

2. GENERAL INFORMATION ABOUT THE Coplay-Whitehall Sewer Authority

SANITARY SEWER SYSTEM

a. Wastewater Treatment and Collection System Description

The Coplay Whitehall Sewer Authority (CWSA) is a Pennsylvania Municipal Authority created

in 1963 by Whitehall Township and the Borough of Coplay under the Pennsylvania Municipal

Authorities Act of 1945, as amended. The sole purpose for the CWSA’s creation is to provide

public sanitary sewer service to the customers (currently 13,850) located within the Whitehall

Township / Coplay Borough service area. The CWSA’s system is a collection and conveyance

system which by Inter-municipal Agreements connects to the City of Allentown’s conveyance

system for treatment of its effluent at the Kline’s Island Wastewater Treatment Plant

(KIWWTP). The Authority is governed by a 7 member Board, 4 members appointed by

Whitehall Township and 3 members appointed by Coplay Borough.

The CWSA’s original system was

constructed during 1965 and 1966

and for the most part consisted of

8” diameter vitrified clay (VCP)

collection mains and reinforced

concrete pipe (RCP) interceptors.

Since completion of the original

system in 1966 there have been

system additions constructed by

the CWSA through Act 537 Plans,

and main extensions by

Developers, which were then

turned over to the CWSA for

future maintenance and repair as

required. CWSA’s system

currently includes 3,311

manholes, 1 pumping station, and

124.80 miles of pipe ranging in

size from 6” to 36” in diameter.

Sewer pipe type includes vitrified

clay, reinforced concrete,

polyvinyl chloride (schedule 40,

SDR 35 and SDR 26, cast iron,

ductile iron and reinforced

concrete cylinder pipe.

In addition to the typical 8” VCP

and 8” PVC collector mains, the

CWSA’s system includes the

following key conveyance

components:

• Jordan Creek Interceptor &


10

Metering Station

• Coplay Creek Interceptor

• Lehigh River Interceptor & Metering Station consisting of different sections as follows

o Lehigh River Relief Interceptor

o Lehigh River Interceptor

o Upper Lehigh River Interceptor

• Eberhart Pump Station & Force Main

The CWSA has entered into Inter-Municipal Agreements with neighboring South Whitehall

Township (SWT) and North Whitehall Township (NWT), which provide for the connection to

CWSA’s system for conveyance of effluent originating from sections of each of these Townships

through the CWSA system for treatment at the KIWWTP. SWT and NWT each have (2)

connections to the CWSA System. SWT connects to CWSA at the SWT’s Jonathan and Quail

Metering Stations and then utilize CWSA’s Jordan Creek Interceptor. NWT connects to the

CWSA System at the Quarry and Omrod Metering Stations and then discharge to CWSA’s

Coplay Creek Interceptor.

The Eberhart Pump Station is located midway along the Lehigh River Interceptor. The Coplay

Creek Interceptor and Upper Lehigh River Interceptor flows are tributary to the Eberhart Pump

Station; these flows are then pumped and discharged to the Lehigh River and Lehigh River

Relief Interceptor and connect to the COA’s Lehigh River Trunk line and ultimately to the

KIWWTP. The second CWSA connection to the COA is through the CWSA’s Jordan Creek

Interceptor to the COA’s Jordan Creek Trunkline and then to the KIWWTP. The CWSA does

not utilize any section of the Western Lehigh Interceptor or any other facilities owned by others

that service the western portion of Lehigh County.

3. CLEANING, INSPECTION AND ASSESSMENT PROGRAM

The Coplay-Whitehall Sewer Authority has consistently used a preventive maintenance plan

(PMP) since the1980’s. This includes a Cleaning, Inspection, and Assessment program to

determine the maintenance needs and structural condition of the entire collection system. The

goal of this program is to completely televise the entire system within a 5 to 6 year period. Once

the entire system has been televised, we then start from the beginning and re-inspect the system

in a round robin 5-6 year cycle.

The Authority’s cleaning, inspection and assessment program focuses on the known problem

areas. The entire collection system is broken down into sub-basins that align with the original

construction contracts for each portion of the system. All data is recorded by drainage basin. The

results from the cleaning, inspection and assessment program are used to categorize the cleaning

frequency and the repair or replacement needs for each component. Critical infrastructure

components will also be identified and assessed. Previous knowledge of the condition of the

sewer system has also been used to establish more frequent cleaning schedules for identified

problem areas.

The cleaning, inspection and assessment efforts are performed by the Authority staff. All data is

entered into the GIS system.

As previously mentioned, all work is performed on a drainage area basis, with the goal of

completing the cleaning and inspection of approximately 15 to 20% of the entire collection

system each year, such that 100% of the system is televised after a 5 to 6 year period. The

drainage basins are each metered and labeled for the purpose of recording the data. All sub-

basins are eventually tied to either of the Authority’s two major drainage basins:

• Jordan Creek Interceptor Basin

• Lehigh River Interceptor Basin

The cleaning, inspection and assessment program includes: sewer cleaning, CCTV inspection of

piping, visual inspection and classification of the manhole structures and their flow channels, and

an evaluation of the condition of the pipes and manholes. Results from the assessment program

are used to categorize the cleaning and inspection frequencies for both the sub-areas and problem

pipe-sections.

The cleaning and CCTV schedules are closely coordinated. As the Authority’s goal is to have a

complete cleaning, inspection and system assessment every 5 years, approximately 20 percent of

the system is reviewed by CCTV each year. Approximately 20 percent of the system is cleaned

annually: the cleaning performed each year includes the priority cleaning plus the remaining

parts of the collection system, factoring in the intermediate and long term interval cleaning

schedules. All of the system cleaning is for gravity lines.

Information from cleaning and inspections (see Inspection section, below), including any

findings, is entered into an EXCEL database, and incorporated into the maintenance software for

scheduled maintenance and capital improvement. This information is also used to update this

long term Preventive Maintenance Plan (PMP). Televised and cleaned lines are also recorded in

the GIS system.


14

a. Cleaning

Our primary sewer maintenance activity is sewer line cleaning.

The cleaning of sewer lines, manholes and other appurtenances is categorized as: priority (annual

or more frequent cleaning); intermediate (2-5 year interval); or long term (6 or more year

interval).

Areas of the system with higher concentrations of restaurants are typically targeted for priority

cleanings. Other priority areas include known structural defect areas, such as sagged lines or

lines with minimal slope.

All cleaning records are kept in a spreadsheet that tracks the following:

• date, time and location of cleaning activity;

• specific lines cleaned;

• equipment used;

• identity of cleaning crew;

• number of passes needed to clean the line;

• presence of root, grease, or debris; and

• problems identified or other follow up actions necessary.

Each line segment cleaned is identified by an upstream and downstream manhole number. A log

is submitted for each day of work completed. Support from outside contractors is also

occasionally used for cleaning and repairs, and for emergencies during non-business hours.

Manhole deficiencies are also noted in cleaning logs. Information about manholes requiring

attention is provided to the Operations Manager and either a repair work order is issued or it is

added to the capital repair schedule.

b. Pipe and Manhole Inspection

Planned manhole and pipe inspections are coordinated with the cleaning program and generally

follow the cleaning schedule. Coplay-Whitehall Sewer Authority uses television inspections to

document:

• the structural condition of the pipe

• root intrusion

• grease

• protruding taps

• evidence of inflow and infiltration (I/I) or surcharging

• manhole pave-overs, and

• other deficiencies that factor into condition assessment

Planned video inspections are generally scheduled to follow the planned cleaning schedule.

However, in the event of a blockage, a video inspection assesses the cause of the blockage.


15

All newly constructed sewer lines are required to be cleaned and CCTV inspected by the

contractor or developer to verify as-built drawings and ensure the line has no construction

defects. Additionally, all new pipes and manholes are required to be pressure tested to ensure

tightness and prevent release of sewer odors and future infiltration of storm water. This

inspection and testing process must be completed before the Authority will accept the

infrastructure from the developer.

Manhole inspections help keep the asset inventory up to date and are used not only to update

collection system maps, but to determine structural condition. During manhole inspections, field

crews take a complete inventory of each manhole including construction materials, ring size,

depth to invert, flow conditions and evidence of problems.

Manhole inspection results are reviewed for condition rating. Those needing repair are placed on

a priority schedule, and routine repairs are coordinated with re-paving work when possible.

When repairs are recommended, as described below, work orders are created..

Authority staff are responsible for completing minor structural repairs to manholes when needed.

Repairs include invert work, frame and cover grade adjustment, and frame and cover

replacement. More comprehensive repairs, such as complete relining of the manhole structure,

are performed by outside contractors.

c. Assessment

Pipe condition information is used to determine short and long term maintenance strategies

including increased cleaning, root treatment, sewer line repair, or replacement. The condition

assessment is used to establish cleaning frequency and inform the Authority’s capital planning.

As more condition assessment information becomes available, the priority of capital projects

may change. Sewer line repair or replacement projects are also coordinated with re-paving

schedules.

All Authority staff are NASSCO certified to perform CCTV inspections and provide a condition

rating assessment.

Condition assessments document the following details and deficiencies:

1. Characteristics including pipe diameter, and age and type of material

2. Dips in line

3. Grease build-up

4. Root intrusion

5. Sediment accumulation and encrustation

6. Structural condition, including cracks, corrosion and erosion

7. Joint alignment and movement

8. Reverse slope

9. Obstructions

10. Deformations in line

d. Staffing and Equipment

Coplay-Whitehall Sewer Authority has multiple staff trained for cleaning, inspection and

assessment of sanitary sewers, and they are deployed in two-person crews for year-round

cleaning and inspection activities. Inspection work is coordinated with appropriate Municipal

officials if traffic control will be needed.

Crews are assigned a specific area of the collection system with an associated map and are

responsible for cleaning all lines (or, in the case of preliminary evaluation, determining if

cleaning is needed) within the assigned area within the specified time frame. Crews receive

training on use of equipment and how to address problems that might be encountered while

cleaning the collection system (roots, fats, oils and grease, and protruding laterals), including

when to call in outside contract services.

Crews report back on a daily basis on progress and problems including any inconsistencies

between the map and the actual sewer lines which are noted and submitted with their log for

entry into the database and correction of mapping or location errors. As the crews perform

cleaning and evaluation, the long term cleaning schedule for the entire sub-area is reviewed to

determine if any lines designated for long term cleaning need to be cleaned before the crew

moves to a new area.

Cleaning crews perform manhole inspections during cleaning and approximately 15% of

manholes are inspected in the average year.

The following equipment is available for cleaning:

• High pressure jet nozzle for light cleaning

• High pressure jet nozzle for heavy cleaning

• Root saw

• Degreaser


17

4. GRAVITY LINE PREVENTIVE MAINTENANCE

a. Fats, Oils and Grease (FOG)

The discharge of fats, oils and grease (FOG) is regulated through our High Strength Waste

program. The High Strength Waste Ordinance sets specific limits on the strength of sewage that

can be discharged to the collection system, and establishes penalties for those customers that are

out of compliance with the requirements.

The Authority works in concert with a testing consultant to collect wastewater samples from

commercial and industrial customers. Protocols have been established for following up with

customers that exceed the discharge limits. In the case of FOG, establishments that serve food

are required to comply with International Plumbing Code requirements for the use of grease traps

or grease interceptors to prevent grease from entering the collection system.

b. Root Control

Coplay-Whitehall Sewer Authority currently uses mechanical root removal for sewer lines with

chronic root problems. Root saw attachments are standard equipment on cleaning trucks. When a

crew encounters roots during routine cleaning, a hydraulic saw is attached to the jetter and used

to cut and remove the roots. The severity of the problem is recorded on the daily log, and if

necessary, the pipe section is placed on the list for priority cleaning. Root control is also a major

part of easement maintenance.

c. Service Laterals

The Authority maintains service laterals from the property line to the sewer main (portions in the

public right-of-way); the service lateral from the building to the property line is the owner’s

responsibility. The Authority will repair laterals that are located in the public right-of-way when

responding to service complaints. If a complaint is received and the field crew determines that

the problem is limited to the section of the lateral between the property line and the main, the

“lower” lateral will be rodded out if needed (at no cost to the customer) if a cleanout is available

at the property line. The Authority also televises this portion of the lateral if needed.

If service lateral problems are found to be the result of blockage or a collapse in the portion of

the lateral under the property owner’s responsibility, the property owner is responsible for the

repair.

d. Grease Control Program

The CWSA has implemented a grease control program to address areas of the system that are

subject to grease accumulations. Known areas are targeted for more frequent cleaning and

include pipe sags and pipes with flat slopes.


18

e. Television Inspection

Television inspection is the backbone of the PMP to identify system defects and anomalies.

Coplay-Whitehall Sewer Authority uses television inspections to document:

• the structural condition of the pipe

• root intrusion

• grease

• protruding taps

• evidence of inflow and infiltration (I/I) or surcharging

• manhole pave-overs, and

• other deficiencies that factor into condition assessment

Planned video inspections are generally scheduled to follow the planned cleaning schedule.

However, in the event of a blockage, a video inspection assesses the cause of the blockage.


19

5. EASEMENTS and PAVING: MAINTENANCE AND ACCESS

a. Maintenance of Right of Way and Easements

Easements are important to operate and maintain the collection system. The Authority’s goal is

that all easements remain clear of any fences, buildings, gardens, trees, shrubs and extensive

landscaping, to allow equipment access for maintenance of the collection system. The Authority

is not liable to repair or replace any such items that are removed in the process of completing

repairs or maintenance on the collection system. Crews are, however, instructed to work with the

property owner whenever possible.

Maintenance of easements is accomplished in various ways. Easements on privately-owned

parcels are often maintained by the owner. The Authority patrols all of its easements at least

annually to ensure that they are clear and accessible. Additionally, the Authority utilizes its farm

tractor with PTO and Brush Hog Rotary Cutter to cut all cross-country easements five to six

times per year to maintain access.

b. Street Paving Coordination

The Authority works closely with Whitehall Township, the Borough of Coplay, and the PA

Department of Transportation to be fully aware of street reconstruction schedules that could be

affected by sanitary sewer repair projects. If the Authority determines that a sewer line or

manhole must be repaired, it will contact the appropriate regulatory agency to obtain a street

opening permit and pay the appropriate fees. If extensive sewer main construction is required

(that is not an emergency), the Authority will include the project in its long-term capital program

so that engineering and planning for the project can be performed.

As sewer lines are inspected and assessed under the Cleaning, Inspection and Assessment

program, repairs are scheduled in conjunction with street repaving schedule whenever possible.

Sometimes work is performed on a priority basis so that repairs are completed on the highest

priority street, working in coordination with the paving schedule of the host municipality.

6. PUMP STATION/FORCE MAIN MAINTENANCE

CWSA owns and operates one wastewater pumping station – the Eberhart Road Pumping

Station. The collection system also includes a few residential grinder pumps that service homes

in various locations throughout the CWSA service area. These grinder pumps are owned by the

customer and are not the responsibility of the CWSA for operation and maintenance. The pump

station owned and operated by CWSA are routinely checked by trained personnel.

The performance of the CWSA pump station is monitored through daily inspections. During

these inspections, a utility technician reviews pump run hours, totalized flow, wet well levels and

alarms. The back-up generator is exercised weekly. On an annual schedule, or more frequently if

needed, a contractor calibrates the flow meter, cleans the wet well, removes grease build up, and

calibrates the floats, and performs other maintenance functions as needed.

Inspection, maintenance and repairs are recorded in log sheets. If a problem or maintenance issue

is encountered, personnel must also report it directly to the Operations Manager for resolution.

Repairs are a higher priority than routine maintenance.

CWSA has a remote alarm system for the pumping station. It remotely monitors pump station

operations, and sends alarms to the on-call staff and Managers in the event of a malfunction or

emergency. The following information can be monitored:

• Number of pumps in operation

• Status of pumps (including operational alarms)

• Power status (including power failure alarms)

• Personnel status (entry / exit alarms)

Manufacturer’s Operation and Maintenance (O&M) manuals for equipment are located in the

offices of the Authority.

Pump rebuilding, motor rewinds, and HVAC repairs for the pump stations are contracted to

outside vendors. Repairs to motor control centers, flow meters, remote monitoring equipment,

valves, and macerators are typically repaired by authorized manufacturer vendors or outside

contractors. In general, any replacement parts that are difficult to acquire are kept in stock on

site. Other parts are obtained from local vendors or the manufacturer’s service center (See Spare

Parts Inventory).

The Authority maintains one spare pump motor and one complete comminutor unit on site at the

pumping station.

Whether repairs are made by local vendors or by Authority staff, all repairs are recorded and

tracked.

a. Mechanical and Electrical Maintenance

The size of the pump station and its related equipment determine its specific mechanical and

electrical maintenance needs. The Operations Manager is responsible for planning the routine

maintenance of each pump located within the pump station. The Operations Manager uses

manufacturers’ Operation and Maintenance manuals to establish action items for pump station


21

equipment. A general description of weekly and bi-annual maintenance performed on pump

stations is listed as follows:

Capacity and discharge head in the pump stations are reviewed annually, following confirmation

that the pumps are in good working order. Changes in capacity and discharge head are evaluated

to determine whether cleaning of the force main is warranted.

All mechanical and electrical maintenance activities are recorded on a log sheet at the station.

Any problems or maintenance issues noted by crews are reported to the Operations Manager for

resolution.


23

b. Force Main Maintenance

CWSA currently has three (3) force mains in the collection system – one force main for each of

the three (3) pumps in the Eberhart pump station. The three force mains are each approximately

1,500 feet long and were designed and constructed with a uniform positive slope to the junction

box discharge point, and therefore air release valves were not warranted.

The pressure on the discharge side of the pump is used to determine the need for force main

cleaning. If the backpressure is more than 25% greater than the expected total operating head,

the discharge pipe will be cleaned. Pressure gauges are inspected during routine maintenance

inspections.

c. Private Pump Stations

The CWSA has no responsibility for any privately owned pumping stations, whether they are

commercial or residential.

d. Corrosion control

The dissolved oxygen content of the wastewater is often depleted in the wetwell of the pumping

station. This wastewater passing through the force main not only lacks oxygen, but often

contains sulfides. These sulfides can lead to corrosion. Frequent turn-over of the wet well at the

Eberhart Road pumping station prevents the formation of H2S in the force main.


24

7. GENERAL EQUIPMENT AND TOOL SUMMARY

a. Essential Day-to-Day Items

The Authority provides operations and maintenance crews with the essential work related items

they use on a day-to-day routine basis. Should new or replacement equipment or tools be

needed, the Field Foreman is authorized to obtain replacements as needed. For non-stocked

items, the Operations Manager will request a purchase order for the needed item(s). The Field

Foreman will then procure the requested items through the local vendor in an “in-stock” format.

b. Spare Equipment and Tools

The Authority maintains a reasonable supply of spare equipment and tools for personnel.

A generalized inventory of the equipment and tools used by the Authority to maintain the

wastewater collection system is provided. A list of supplies and essential spare parts necessary to

be kept on site for normal and emergency use is included. Specialized attachments are often

used with these tools to perform specialized maintenance tasks.

8. CAPACITY MANAGEMENT

a. Sewer Capacity Certification/ Connection Policy

The Sewer Capacity Certification is a process where any new development requiring the

connection of its sanitary sewer service to the Authority’s sewer system is reviewed to determine

whether adequate sewer system capacity exists to convey the new wastewater flow from the

proposed development to the City of Allentown’s wastewater treatment facility. A capacity

certification analysis is required for all developments, or any existing customer that requires an

increase in its sewer allocation. The certification process also assigns the development capacity

within the Authority’s current treatment allocation within its Agreement with the City of

Allentown.

This process aligns with the processing of Sewage Facilities Planning Modules with the PA

Department of Environmental Protection.


26

9. RESOURCES AND BUDGET

a. Budget Process

The budget is a part of the Authority’s overall budget cycle. Specific items related to the

operation of the sewage collection system are identified under separate categories within the

budget. Authority staff works with the Finance Committee to present a budget to the complete

Authority Board for approval. For the Collection System operations and maintenance budget, the

process begins with last year’s numbers and projected needs for the next budget year. The

Authority maintains a multi-year budget process to manage anticipated expenses.

b. Rate Review

The current sewer rate structure is based on metered water usage. Customers are billed quarterly

for wastewater services based on 100 % of the metered water use. In addition to flow charges,

customers are also assessed a base charge to recover fixed costs. Rates are examined and

adjusted as needed based on anticipated O & M and Capital expense for the sewer system.

c. Operating and Maintenance Expense

Operating and maintenance expenses include:

• Employee salary and compensation

• Operating supplies

• Utilities

• Repair and maintenance

• Professional services

• Routine capital outlay

• Debt service expenses for repair and replacement

Professional Services includes planning and engineering studies for replacement projects and

daily operations.

Contractor Services includes contractual work for cleaning sewer lines and manholes, CCTV,

and improvements to the collection system map.

Routine Capital Outlay includes items that are considered capital assets and are purchased from

annual operating revenue rather than through bonds or the capital reserve fund. Items such as

vehicles, specialized maintenance equipment, pumps, motors, office equipment and other smaller

items.

Debt service is the annual principle and interest payments for bonds, loans and other fiduciary

instruments owed by. The debt service supports capital improvement projects.

d. Capital Improvement Program Overview

The Authority has prepared a 5-Year Capital Improvements Plan to address the implementation

of projects that are essential to the long-term successful operation of the sanitary sewer system.

The 5-year Plan addresses the following types of projects:


27

• Excavation repairs to replace defective pipe segments

• Trenchless repair of isolated pipe defects

• Lining of existing sanitary sewers

• Replacement of sanitary sewers and sewer laterals

• Manhole rehabilitation

• Continuous sewer televising and cleaning

• Updates and improvements to flow measurement facilities

The 5 year budget is intended to be a fluid document that can be adjusted as necessary to meet

the Authority’s needs. The plan will be reexamined each year and projects will be added,

adjusted, or revised as necessary as work is completed and new work is identified.


28

10. SEWER SYSTEM PREVENTIVE MAINTENANCE PLAN UPDATES

a. Plan Update Process

Coplay-Whitehall Sewer Authority will complete reviews of its Preventive Maintenance program

annually. This will be done in conjunction with the preparation of its annual “Chapter 94

Report” that is prepared for review by the Department of Environmental Protection. The review

will consider the progress that has been made in implementing its Preventive Maintenance

Program, the results of monitoring programs, and will incorporate updates to this Plan including:

• Changes to organizational structure, information management, contacts, and system

maps,

• Changes to information on the collection system, such as the size and age of pipes, to

incorporate information on repairs completed during the year,

• Incorporation of successful cleaning, inspection and assessment program improvements

during the past year,

• Changes to the Sewer Use Rules and Regulations

• Budget and Capital Planning updates

b. Monitoring, Measurement, and Program Modifications for Infiltration and Inflow

Source Reduction

The Authority will maintain records of key information to continually assess improvements to

the collection system.

The information will measure the effectiveness of the Maintenance program by tracking various

parameters related to service calls and maintenance and inspection activities. Comparison of

trends from previous years and identifying system defects are key components. Tracking the

following parameters will measure the effectiveness of the Plan and its effectiveness in reducing

Inflow and Infiltration:

• Number and cause of SSOs per year

• Length of gravity sewers cleaned annually

• Home clear water inspections

• Manhole Inflow Prevention Inserts Installation

• Manhole and manhole chimney rehabilitation

• Actual versus scheduled cleaning dates for gravity sewers

• Length of gravity sewers CCTV inspected annually

• Percent of system rehabilitated (repaired or upgraded) each year

• Improvements in capacity due to reductions in I/I

• Safety history/incidents

• Continuous tracking of average and peak flows within each metered drainage basin to

determine the effectiveness of repair and maintenance activities.


29

The Authority has been implementing an aggressive maintenance and capital improvements plan

for over 30 years. These programs are well into their maturity stage, as the Authority has

replaced or updated a number of its major system components within the last 20 years as

identified below:

1. Jordan Creek Interceptor Replacement Project ................................... Final Completion 2009

2. Collection System Repairs .................................................................. Final Completion 2011

3. RT-22 Crossing ................................................................................... Final Completion 2012

4. Coplay Creek Interceptor Replacement .............................................. Final Completion 2013

5. Lehigh River Interceptor Relocation – LSB ....................................... Final Completion 2013

6. Ruch Street Replacement .................................................................... Final Completion 2013

7. SR 22 Section 400 Replacement ............................................... Final Completion 06-30-2015

8. Lehigh Meter Station & Pipe Replacement .............................. Final Completion 11-11-2016

9. Front Street Coplay Replacement ................................... Substantial Completion 11-11-2017

10. Front Street Coplay Improvements ................................................................ Work in process

Since 2008 the Authority has spent close to 15 million dollars on upgrades, replacements, and

improvements to its wastewater collection system.

Following the completion of its Capital Program between 2008 and 2013, the CWSA performed

an analysis to determine the effectiveness of the completed work. The following results were

obtained:

ITEM DESCRIPTION

PRE CONSTRUCTION

(2009)

POST

CONSTRUCTION

(2014)

Flow to Allentown 2.037 MGD 1.927 MGD

Connections 13,470 13,735

Flow per EDU 146 gpd 136 gpd

Average daily flow reduction 110,000 gpd

Peak Flow Reduction 789,000 gpd*

* Variable depending on type and intensity of precipitation.

These results demonstrate the effectiveness of the Authority’s previous efforts, and more

importantly show that maintenance of the programs in place will continue to yield similar, if not

better results.

The CWSA will continue to implement its 5-year television inspection/cleaning program over its

entire collection system and implement repair and replacement projects as system defects are

identified. Continuous monitoring of Lehigh River and Jordan Creek Interceptor basins will

show the CWSA the effectiveness of all work performed via the monitoring of peak flows, total

daily flows, and precipitation.
