Sewer Emergencies/After Hours: (510) 222-6700


West County Wastewater (WCW) is devoted to the community we serve – protecting both public health and our natural surroundings. With that responsibility comes our dedication to keeping residents informed about what’s happening with wastewater at WCW and in the region.

Whether it is FOG (fats, oils, grease) and wipes education or describing the wastewater treatment process, WCW educates the community about wastewater and the value of wastewater service. We offer a variety of educational opportunities, such as Water Quality and Resource Recovery Plant tours, public presentations and school visits, on-site business pollution prevention support, and involvement at community events.

At WCW, we believe our role in the community goes beyond providing wastewater service and into supporting and nurturing strong, diverse and vibrant neighborhoods.

The WCW team is dedicated to reliable, high-quality service, which includes working to ensure our wastewater system functions properly. We inspect, maintain, upgrade, and construct the buildings, systems, and sewer lines that collect, treat, and dispose of wastewater. This includes maintaining and improving public sewer pipes, pumps, and mains in our community, as well as the systems at our Water Quality and Resource Recovery Plant.



WCW customers play a key role in our mission of protecting the environment and public health. That’s one of the many reasons we value community engagement, including providing information about the value of wastewater service and educating customers on how to help keep local neighborhoods, homes, parks, and natural surroundings safe.

You may interact with us at a community event, hear about us from your child after a school visit, see us inspecting public sewer lines, or meet us by taking a tour of our Water Quality and Resource Recovery Plant.

Schedule a plant tour! Call (510) 237-6603.
Tours are temporarily on hold due to the COVID-19 pandemic.

Learn about WCW’s role in wastewater services and how our treatment plant operates. Tours are available for interested residents, school classes, youth groups, businesses, or other organizations. To request a WCW classroom visit, presentation, or attendance at a community event, call (510) 237-6603.


West County Wastewater hosted our first Community Cleanup on April 30, 2023.

This was a wonderful opportunity to join together to protect and preserve Wildcat Canyon Creek, in Richmond.

With over 25 volunteers we removed over 1,500 pounds of debris!

Educating students about environmental responsibility, including water as a precious resource, is vital to protecting our future for generations to come. WCW’s Student Outreach program engages students at a young age through school classroom visits and tours of the Water Quality and Resource Recovery Plant. To schedule a classroom visit or a plant tour, contact the Water Quality and Resource Recovery Plant at (510) 237-6603. Bus transportation assistance may be available.

Classroom Connections

More than 1,000 local school children from grades four through seven participated our Student Outreach Program last year.

Smart about Sewage

How efficiently we treat and manage our wastewater plays a major role in achieving effective water resource management. Safe and responsible collection and treatment of wastewater protects our planet and our families now and for years to come. Use the resources below to help children learn how the wastewater process works and how it relates to protecting and preserving our water and the environment.



As a society, we rely on skilled, experienced professionals to collect and distribute drinking water, treat wastewater safely and efficiently, test water quality in laboratories and help communities conserve water. Water and wastewater career options represent tremendous opportunities for people with many different backgrounds, talents, and skills. In partnership with the Bay Area Consortium for Water and Wastewater Education (BACWWE) and Solano Community College, WCW is proud to support local education of future water and wastewater professionals, as well as hire graduates from the program.

Wondering what it’s like to work in the water or wastewater world?

Operators at water or wastewater treatment plants make sure water meets strict environmental regulations. Employees in operations and maintenance departments keep water distribution systems and wastewater collection pipelines running smoothly. Others might work with state-of-the-art computer systems to control pumps and valves regulating the flow of millions of gallons of water, or in a laboratory testing samples, or the field using heavy equipment to dig trenches to repair pipelines.

The BACWWE program offers many different options, both in terms of entering the field (from entry level to management) and the type of work setting (treatment plants, offices, or outdoors). A career in the water or wastewater industry has many advantages, including:

  1. These local careers are here to stay because they are the types of careers that cannot be outsourced. There’s a need for these careers all over the world, so the skills can be applied at any location.
  2. There’s steady demand for these careers now and into the future, thanks to the continuing need for water-related expertise and the wave of retirements happening now and anticipated in the future.
  3. They address water conservation and sustainability, making them green careers.
  4. Careers in water and wastewater offer a range of competitive pay and benefits based on skill and provide stability.
