Save the Waters You Love

Boaters of all kinds enjoy the waters of the San Francisco Bay-Delta Estuary, a unique spot for year-round recreational and commercial boating. These boaters can, however, impact the quality of the Estuary waters they enjoy. In particular, untreated sewage discharged from boats can cause localized effects on water quality and public health, especially in semi-enclosed marinas and harbors where minimal water flushing occurs. Sewage from houseboats and other live-aboard vessels is a particular concern in parts of the Estuary, specifically Richardson Bay, Alviso Slough, Redwood Creek and the Delta.

Under a Clean Vessel Act grant from the California State Parks Division of Boating and Waterways, the Estuary Partnership manages a dynamic Education/Outreach and Monitoring program aimed at encouraging boaters to use pumpout and dump stations rather than discharging directly into the Estuary.

What is the likelihood that a boater will have a positive experience at a given pumpout?

SFEP and The Bay Foundation have been monitoring pumpouts throughout California for almost a decade and have used the most recent data to write this report.


Come meet us in person twice a year at the Pacific Sail & Power Boat and the Sacramento Boat Shows! We’ll have good information to share. Or invite us to give a presentation on clean boating practices at your club by emailing at



One tool to help build stronger pumpout networks in the Delta involves convening marinas to discuss shared challenges and solutions.



Properly disposing of boat sewage helps improve water quality and maintains the marine environment that we all enjoy! Watch this video to learn how to properly secure your Y-valve to prevent an accidental discharge.


Stands for Best Management Practices! If you are a marina or boat facility manager, this handy booklet informs you on today’s material and practices leading to an even more environmental facility!

Our ongoing mission

Education & Outreach

For more than two decades, the San Francisco Estuary Partnership has been working in the 11 counties of the San Francisco Bay and Sacramento Delta to promote clean boating and environmental stewardship to boaters and marinas, in partnership with the California State Parks Division of Boating and Waterways (DBW), The Bay Foundation, the Coast Guard Auxiliary, and a vast array of other partners.

Our multifaceted educational campaign is focused on in-person boater education, regional capacity building, and pumpout network enhancement. The combination of boater and marina education and capacity building serves to address the complex nature of sewage discharge by providing boaters with the information they need to make correct decisions and provide marinas with the tools they need to work with boaters to proactively prevent sewage discharge.

Keeping a functional pumpout network


For over 10 years we have regularly monitored the roughly 80 publicly accessible pumpouts in the Bay and Delta for their use and condition. We notify marinas of broken or malfunctioning units and work to make sure units have proper signage. This fruitful collaboration has maintained a highly functioning pumpout network, with roughly 90% of pumpout stations consistently operational.

New nozzle tips, ball valves and other small parts are given to marina operators with damaged equipment. This helps ensure that the boaters using the pumpout network are not deterred by collapsing nozzle tips that commonly impede flow.


Download the free app by searching for Pumpout Nav in your device’s app store. Locate the closest operational pumpout to your location, learn how to operate a pumpout, or report any issue you might have.
