CWSRF Projects Being Considered:
Applicant: City of Clairton County: Allegheny Applicant Address: 1 North State Street
Clairton, PA 15025
Project Description: The construction project will modify the Clairton Municipal Authority Sewage Treatment Plant to eliminate untreated wet weather sewage overflows. The existing conventional activated sludge process is being converted to a membrane bioreactor (MBR) process. Two existing primary clarifiers will be converted to MBR effluent water storage tanks and a back-up MBR chlorine contact tank. Four existing aeration tanks will be converted to MBR tanks while four existing secondary clarifiers will be converted to combined sewer overflow (CSO) storage and primary clarifiers. Two existing chlorine contact tanks will be converted to CSO disinfection. The existing chlorine gas disinfection will be converted to liquid sodium hypochlorite for chlorination and liquid sodium bisulfite for de-chlorination. Design peak flow will be 38.23 million gallons per day (mgd).
Problem Description: This project is being implemented for the City of Clairton to comply with its Long-term Control Plan. This project will reduce CSO bypasses within the system and eliminate sanitary sewer overflows that occur from the Peters Creek interceptor.
Applicant: Elizabeth Township County: Allegheny Applicant Address: 522 Rock Run Road
Elizabeth, PA 15037
Project Description: The proposed project will eliminate the Buena Vista wastewater treatment plant (WWTP) by constructing a new pump station (PS) and equalization basin and upgrading the existing Boston PS. The proposed new Buena Vista PS will have a capacity of 3.9 mgd. The associated equalization basin will have a capacity of 3 mgd. The upgraded Boston PS will have a capacity of 17.5 mgd. Flow will be sent from the Buena Vista PS to the Boston PS by means of a new single force main. A new force main will also be constructed from the Boston PS along the Great Allegheny Passage to an existing pipe junction. Sewage will flow to the Municipal Authority of the City of McKeesport's Sewage Treatment Plant.
Problem Description: This project will eliminate capacity-related sewage overflows at the WWTP. The Boston PS is also being upgraded to accept the flows from the new Buena Vista PS and to eliminate capacity-related overflows that occur at the Boston PS.
Applicant: Marion Township County: Butler Applicant Address: 2275 West Sunbury Road
Boyers, PA 16020
Project Description: The project will serve the existing 24 customers from the southeast corner of the Village of Boyers, as well as an additional 87 customers from the Atwell Crossing area located west of the existing sewage facility. The system will be designed to treat the proposed 111 customers as well as future developments. This project consists of purchase and installation of approximately 1,540 linear feet of 8-inch standard dimension ratio 35 PVC gravity sewer main, 200 linear feet of 1.25-inch, 1,900 linear feet of 1.5-inch. 2,750 linear feet of 2-inch, and 5,250 linear feet of 3-inch high-density polyethylene sewer main, 845 linear feet of 4-inch sewer lateral and 8,115 linear feet of 1.5-inch sewer lateral, 90 grinder pumps, 12 manholes and appurtenances. The plant will consist of an influent duplex submersible PS, three 22,000-gallon baffled septic tanks in series, a recirculation vault, a 13,500-gallon dosing tank with two submersible pumps, two 9,540 square feet open recirculating sand filter beds, a tablet chlorine disinfection with a 2,000-gallon chlorine contact tank and a tablet dechlorination system.
Problem Description: Within the project area, many properties within Marion Township currently utilize onlot systems for the disposal of sewage, while a centralized public system serves a small portion of the Village of Boyers in the southeast corner of the Township. The sewage system includes a gravity fed pumping station, two waste stabilization ponds (sewage lagoons) and an outlet structure. The lagoons are no longer viable. The lagoons contain cattails and duckweed. The embankments are overgrown with trees, shrubs and other vegetation. The headwall collapsed causing the embankment to leak. No adjustable draw-off devices exist to regulate flow between the lagoons. Discharge flows are not measured. The fencing around the lagoons is damaged and missing in several locations. There is no disinfection of the effluent. Due to these conditions, the lagoons are not operating properly nor has the system ever been permitted. A sanitary survey was conducted in 2012 which determined there was a 54% confirmed onlot failure rate associated with this area. The malfunctions include direct discharges (sewage or grey water) to ditches, surface malfunctions, discharges to catch basins, discharges to storm sewers, piped discharges to streams, discharges into woods and reported back-ups. The inability of the existing sewage lagoons to continue serving its existing customer base and a majority percentage of onlot systems within these areas having confirmed malfunctions, necessitate the need to extending public sewerage to the Village of Boyers and the Atwell Crossing area, in addition the expansion and improvement of the treatment facilities.
Applicant: Washingtonville Municipal Authority (Authority) County: Montour Applicant Address: P.O. Box 147
Washingtonville, PA 17784-0147
Project Description: This project consists of constructing a new WWTP immediately adjacent to the existing WWTP at the existing site. The new equipment that will be installed includes a fine screen, new sequencing batch reactor treatment process tanks, new sludge handling facilities and a change to the existing disinfection process. No changes in plant capacity are proposed as part of this project.
Problem Description: The existing WWTP serving the Authority was built in 1972 and is nearing the end of its useful life. Most of the original equipment is still in service. In 2015, the Authority contracted to have a steel treatment tank cleaned and painted. Due to lack of structural integrity of the tankage, mechanical cleaning could not be performed. A temporary coating was applied that extended the life of the tankage; however, the plant now needs to be replaced.
DWSRF Projects Being Considered:
Applicant: Indian Lake Borough County: Somerset Applicant Address: 1031 Causeway Drive
Central City, PA 15926
Project Description: The proposed project involves constructing a new pressure filter treatment plant with three filters, permitting Well 18B, rehabilitating Well # 99, installing a new water storage tank and installing a new 6-inch waterline from Well 18B to the existing Well # 99. The new water treatment plant is designed to include a pressure filtration system with zero-backwash discharge to remove iron and manganese. Well # 2 will be removed from service at the completion of the project.
Problem Description: Indian Lake Borough is currently served by multiple wells and is permitted to use Well # 99 and Well # 2. The existing treatment includes chlorination by sodium hypochlorite at Well # 99 and sequestration along with disinfection at Well # 2. The water quality from Indian Lake Borough shows that Well # 99 and Well # 2 have degraded and both show elevated iron and manganese values. This project will improve finish water quality for the service area.
Applicant: Windber Area Authority (Authority) County: Somerset Applicant Address: 1700 Stockholm Avenue
Windber, PA 15963
Project Description: This project includes rehabilitating the existing Clear Shade Tank No. 1 without an interruption in service. The Authority proposes to construct a new 500,000 gallon glassed-fused-to-steel water storage tank (Clear Shade Tank No. 2). This new tank will be located next to Tank No. 1. After Tank No. 2 is constructed and put into service, Tank No. 1 will be taken offline. Tank No. 1 will then undergo interior rehabilitation. The interior rehabilitation will include cleaning the tank, re-edging and coating the shell seams, installing new sacrificial anode bars, inspecting and repairing glass chips, replacing missing hardware, and testing and disinfecting the tank. After Tank No. 1 is repaired, it will be put back into service. Tank No. 2 will provide redundancy for water storage as well as allow either tank to be taken out of service for maintenance without interruptions in service.
Problem Description: The Authority currently operates a 500,000 gallon, glassed-fused-to-steel water storage tank. Clear Shade Tank No. 1, which was constructed in 1991, needs repair due to age. The tank underwent an exterior rehabilitation in 2015 but is still in need of interior repairs. This tank is currently the sole entry point for the system. Taking the tank offline for interior repairs would result in an interruption of service to approximately 9,200 existing customers. The proposed project is to construct an additional storage tank so needed repairs can be made on Tank No. 1 without interruptions to service. The project will add much needed finish water storage to the existing water system.
