Clean & Healthy Creeks
When you take a shower or wash clothes in your home, the rinse water goes down the drain and into the sewer system to be treated. Outside your home, things are very different. Everything that flows into a storm drain goes untreated directly into our local creeks and ultimately, into the ocean. Our nearby wildlife, plants, and humans are dependent upon these bodies of water for habitat, livelihood and recreation. Unfortunately, the stormwater runoff from our urban Cityscape that enters the local watershed is often polluted by pesticides, fertilizers, litter, pet waste, motor oil, eroded soil, and household chemicals.
Stormwater is managed through implementation of the City’s National Pollutant Discharge Elimination System (NPDES) permit.
A stormdrain is located at the end of most street blocks and is commonly mistaken (PDF) as a sewer.
Stormwater is Untreated
The purpose of a storm drain is to direct rainwater into rivers, creeks, streams, and other large bodies of water to prevent flooding in the City. Stormdrain water is not treated, and will end up in one of two places:
- Reservoirs used for drinking water
- Local creeks and the bay used for recreation and by wildlife
For more information, contact the Environmental Services Division.
