The Tredyffrin Township Public Works Department maintains approximately 133.6 miles of sewer line, 3,840 manholes, and nine pump stations. These facilities are owned by the Tredyffrin Township Municipal Authority, while the Township operates and maintains them. This system of gravity lines, force mains, and pump stations convey sewage to one of four sewage treatment plants: Valley Forge Sewer Authority (Phoenixville), Trout Run (Upper Merion), Matsunk (Upper Merion), and Delcora (Chester).
Tredyffrin Township is also the owner of the Valley Creek Trunk Sewer. This trunk line conveys sewage from 6 member municipalities (Tredyffrin, Easttown, East Whiteland, Malvern Borough, Willistown Township, and Valley Forge Sewer Authority) to the Valley Forge Sewer Authority's treatment plant.
Property Owners: Each property owner is responsible for the repair and maintenance of their lateral, which is their sewer connection from the house to the sewer main.
The Township pays for sewage treatment by the gallon. The reduction of water into the system can help reduce sewage treatment costs. How can residents help? In several ways: by making sure sump pumps are not connected to the sewer, clean outs are at least 6 inches above the ground and capped, and by keeping their laterals in good shape. The fewer illicit connects to the sewer system, the less we all pay in treatment costs.
Disposal of Swimming PoolWater and Chemicals
Per PA Department of Environmental Protection regulations [PDF], pool water and other wastewater cannot be discarded into the storm sewer, groundwater, stream or other natural water source.
To properly dispose of pool water and other waste water, you must contact the Tredyffrin Township Public Works Department for permission to discard into the sanitary sewer system. The Public Works Department will grant approval if the residents follow the DEP Guidelines for waste water disposal, the water conforms to the sewage treatment plant requirements, and there is a public sewer in close proximity to the pool discharge point. The cost for the discharge is $6.51 per thousand (1,000) gallons.
If anyone is concerned about possible improper discharge of pool water into any street or stream or into the sanitary sewer system, please contact the Township (610-408-3620) immediately. If a potential problem is noticed after business hours, please call the Police (911).
Chemicals and paints also should not be disposed of in the sewer or storm drain systems. The Chester County Health Department holds free household hazardous waste collection events each year.
