Water Pollution Control Plant Infrastructure

Sunnyvale’s Water Pollution Control Plant treats and cleans wastewater from Sunnyvale businesses and homes prior to discharge into the San Francisco Bay. At almost sixty years old, the Plant began undergoing major construction and much needed upgrades in fall 2014.


The SMaRT Station

The SMaRT Station accepts recyclable materials and self-hauled garbage from residents and businesses in Sunnyvale, Mountain View and Palo Alto.


Sunnyvale has Zero Waste goals!

The work of the Recycling Program supports the Zero Waste Strategic Plan adopted by the City Council in 2013. Sunnyvale has achieved a current rate of 66% diversion from landfill and the goal is 90% by 2030. Photo credit: Bill Watson

What Does the Newly Approved Climate Action Plan Mean for the Sunnyvale Community?

In May 2014, the City Council adopted the City’s first Community-wide Climate Action Plan.  The Climate Action Plan is Sunnyvale’s path toward creating a more sustainable, healthy, and livable Sunnyvale. The strategies outlined in this Plan will not only reduce GHG emissions, but will also provide energy, fuel, water, and monetary savings while improving the quality of life in Sunnyvale. As the City continues to transform, the Climate Action Plan will help the City streamline future environmental review of development projects in Sunnyvale by following the California Environmental Quality Act (CEQA) Guidelines for a Qualified GHG Reduction Strategy.


To report non-emergency discharges or dumping of non-hazardous materials into storm drains, call (408) 730-7260, TDD (408) 730-7501 from 7 a.m. - 4 p.m. Monday through Friday. After hours, call (408) 730-7181, or e-mail the information to the WPCP.

For emergency reports of hazardous spills or dumping into storm drains, call 9-1-1 or (408) 736-6244

Remember – only rain down the drain.



Graywater is tap water that has already been used for one purpose (commonly washing clothes or people) and then instead of going down the drain is diverted to landscaping to water plants.

Things to know about graywater for health and safety:

When the graywater gets out to the landscape, make sure the exit point is buried in mulch because graywater should not be sprayed in the air or come in contact with edible parts of plants.
Graywater should not be used to irrigate root vegetables.
Graywater should not be stored--you need to use it within 24 hours and no puddles. You'll be watering live plants, so choose non-toxic detergents and soaps and avoid salts, boron, and bleach.

No building permit is required when planning to divert water from a clothes washer, but other diversions might. Contact the Building Safety Division at (408) 730-7444 or email Building@Sunnyvale.ca.gov for more information.
