Stormwater System The Stormwater Drainage System is not the Sanitary Sewer System
The Storm Water System is a series of underground drains to direct rainwater (stormwater runoff) to the creeks and tributaries that flow to the bay. The Stormwater Drainage System (also known as the Storm Drain System) is completely separate from the Sewer System which links home plumbing (sinks and toilets) to the sewage treatment system processing plants.
It is very important to keep these 2 systems separated, and to manage what goes in each system. For instance, it is OK to drain pools and spas into the sewer system (hook up to your clean-out or washer outlet) but absolutely do not drain spa or pool water into the curb/storm drain system as the treated water contaminates creek and bay water. Also, to help keep the storm drains clear and flowing, please do not sweep leaves from sidewalks into gutters (use your yard waste bin provided by West Valley Collection & Recycling.

Stormwater Pollution Information
Unfortunately, our everyday activities can pollute stormwater. Please visit our Stormwater Pollution Prevention page for information on what you can do to prevent stormwater pollution.
Carwash Fundraisers As part of the Town’s permit from the San Francisco Bay Regional Water Quality Control District to discharge water into creeks that flow to San Francisco Bay, only storm water can be discharged into the Town’s drainage system. Water that contains soap and other contaminants from washing many cars is a violation of Town Code Section 22.30.015(a) and (b). If proper procedures aren’t followed, you or organization may be cited and fined.
Thanks to our partners in the fight against water pollution, the West Valley Clean Water Authority, a fund-raiser car-wash kit has been put together. The kit has plugs that will block the storm drain inlet and a submersible pump to pump the contaminated water on to a landscape area, where natural biological action will rid the water of contaminants before it is absorbed by the ground or flows to another storm drain inlet.
The kit is available free of charge to organizations planning a fundraiser. Please contact the West Valley Clean Water Program at 408-354-5385.
