Stormwater does Affect Water Quality.
PWSA draws water from the Allegheny river. Anything that enters the storm sewer is ultimately released, untreated, into the rivers and streams.
The PWSA system is made up of sanitary, dedicated stormwater and combined sewers. All new development is required to have separate storm sewers into Municipal Separate Storm Sewer Systems, known as MS4's.
Clean Water is Everybody's Business
What is Stormwater?
“When it Rains it Drains” is a pamphlet that provides an overview of stormwater.
The pamphlet answers frequently asked questions such as: What is it? Why is it a problem? What can you do to help?
What can you do to help?
- Dispose of trash properly. Don’t Litter.
- You can help reduce costs and keep our rivers clean by properly disposing of waste.
- Consider the location where you wash your car
- If you’re washing your car in the driveway, all the soap is going into the street, entering the storm sewer and eventually ending up in the river.
- Properly dispose of Pet Waste
- If pet waste is not properly disposed of, during rain events, the bacteria will enter storm sewers and eventually end up in the river.
- Use fertilizer sparingly
- During rain events, fertilizer runs down the street, enters the storm sewers and eventually ends up in the river. Don’t fertilize before a rain storm.
- Stop oil leaks immediately
- Leaking oil runs down the street, enters the storm sewers and eventually ends up in the river. Check for oil leaks regularly and dispose of oil properly.
- Three Rivers Wet Weather
- Three Rivers Wet Weather was created in 1998 to help Allegheny County municipalities address the region's aging and deteriorating sewer infrastructure and to meet the requirements of the federal Clean Water Act.
- Nine Mile Run Watershed Association
- The mission of this group is to ensure the restoration and protection of the Nine Mile Run Watershed, located in Pittsburgh's East End.
