After managing the City’s Wastewater Treatment System for fifteen years, the Johnstown Redevelopment Authority purchased the wastewater treatment system from the City in October of 2004, and began operating all aspects of the treatment system. The wastewater treatment system currently consists of the upgraded Dornick Point Wastewater Treatment Plant and the interceptor lines located within the City of Johnstown and West Taylor Township. (An interceptor line is a line conveying wastewater from more than one municipality).
The Greater Johnstown Wastewater Treatment System consists of the wastewater treatment plant, interceptor sewer lines, and individual collection systems in each municipality. The Redevelopment Authority is responsible for the treatment plant and the large interceptors within the City of Johnstown. The collection systems and smaller interceptors are the responsibility of the municipalities in which they are located.
The Dornick Point Sewage Treatment Plant provides service to all or a portion of the following 20 municipalities:
|City of Johnstown||Jackson Township|
|Brownstown Borough||Lorain Borough|
|Conemaugh Township (Cambria & Somerset)||Lower Yoder Township|
|Daisytown Borough||Richland Township|
|Dale Borough||Southmont Borough|
|East Conemaugh Borough||Stonycreek Township|
|East Taylor Township||Upper Yoder Township|
|Ferndale Borough||Westmont Borough|
|Franklin Borough||West Taylor Township|
Dornick Point OVERVIEW
- 1960: The plant was originally built and placed on-line as a primary sewage treatment and sludge incineration plant.
- 1986: The City and Redevelopment Authority began work with the US EPA and PA DEP to upgrade the plant to secondary treatment. (http://www.johnstown-redevelopment.org/stp.htm)
- 1989: Construction was completed on the secondary treatment upgrade. Because of space limitations, the secondary treatment process was designed as pure oxygen activated sludge. By utilizing pure oxygen rather than atmospheric air, the aeration tank is one-fifth the size that would be necessary for a conventional activated sludge treatment plant.
- Originally, oxygen was produced on-site via a pressure swing adsorption (PSA) system and used from 1989 until 1999.
- The plant now uses liquid oxygen at a rate of 5-10 tons per day. It is vaporized on site and then utilized in the system.
- 1990: Program to reduce/eliminate Inflow and Infiltration of storm water into sanitary system continues in compliance with an existing Corrective Action Plan.
- 1995: Landfilling of sludge began.
- 1997: Lime-stabilization of the sludge was introduced to reduce odors.
- 1999: The PSA system was shut down for economic reasons.
- 2001: Contracts were arranged to have the first land application of biosolids started.
- 2002: Sludge produced at the plant is continuously being used for beneficial use via land application. The plant produces 20,000 tons of lime-stabilized biosolids per year.
- 2004: Started a program incorporating better designed manhole lids to prevent stormwater from entering into sanitary sewer system.
- 2004: Johnstown Redevelopment Authority purchased the Dornick Point Wastewater Treatment System from the City and began all operating aspects.
- 2005: Purchased in-line meters to begin monitoring the volume of wastewater flows coming into the city interceptors from contributing municipalities and began repair work on several inceptor lines within the City.
- JRS performs annual cleaning and inspection of the interceptor siphons which carry wastewater beneath rivers and streams.
- There are 113 miles of sanitary sewer collection and interceptor lines within the City of Johnstown!
