Clean Water Program

Storm water runoff is the leading cause of water pollution today. When water flows over land it can become contaminated with materials like oil, pesticides, trash, and whatever else is on the ground. It runs down storm drains and flows right into our creeks and the San Francisco Bay.

Services provided through the Clean Water Section for unincorporated areas of Alameda County include commercial and industrial inspection, watershed assessment and monitoring, new development and construction site control and public outreach.

Alameda County's Clean Water Program works with other County departments and agencies to help ensure that the County meets the requirements of its storm water permit with the San Francisco Bay Regional Water Quality Control Board. We work with people throughout the unincorporated area of Alameda County to protect and enhance the quality of water in our local creeks and watersheds. 


Whatever gets into the ground can harm our waterways.  

Here are some tips on how you can prevent storm water pollution:

  • Put trash in its place.
  • Keep cars free of leaks.
  • Use less/non-toxic ways to deal with pests around the home and garden.
  • Never clean paint brushes or rinse containers into the gutter or stormdrain.

Remember – only rain down the storm drain!

We work with a variety of local businesses and professionals to help them understand how storm water quality regulations affect them, and to support companies in adopting techniques that help protect our waterways and the bay.
