Philadelphia Water (PWD) is responsible for maintaining the health of our local waterways, and stormwater runoff is the primary source of pollution in our rivers and streams. When it rains, stormwater runoff:
- Contributes to combined sewer overflows;
- Pollutes our rivers with fertilizers, oil, and sediment;
- Destroys valuable aquatic and riparian habitat; and
- Floods homes and businesses.
PWD developed its Stormwater Regulations in response to the challenges that stormwater presents.
