Clean Vessel Act Grant Program

Project At a Glance

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.

California Pumpout Report
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.

Universal Adapter Kits Available!
This program helps to champion clean boating and reduce pumpout frustrations

This exciting project aims to overcome challenges faced when using pumpout stations by making it a simpler, cleaner, and hands-free experience. Request a free Adapter Kit today!

Boat Shows & Yacht Club Presentations

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

Delta Capacity Building

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

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.

NEW! SFEP partnered with The Bay Foundation’s Clean Vessel Act (CVA) Program to develop Pumpout Nav, a free Android and iOS App that allows CVA surveyors, marina managers and boaters to monitor pumpouts, helping maintain an operational network.



Pumpout Nav!

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.

SFEP has worked with the California State Parks Division of Boating and Waterways and The Bay Foundation in southern California to write the 2018 CA Pumpout Report

Grant Opportunities

Marina managers: is your pumpout too expensive to maintain, or do you need a new one? Grant money is available from the Division of Boating and Waterways through the CVA Operation & Maintenance or Installation Grants. How to apply?

Pumpout Maintenance

Keep your marina’s pumpout in top condition with the help of the Pumpout System Maintenance Guide video series produced by the Oregon Sea Grant team. Watch the Videos

Throughout California

Well, almost:

Pumpout Nav covers eleven counties of the San Francisco Bay Area and Sacramento Delta, as well as the five Southern California counties from Santa Barbara to San Diego. Look for more states coming on to the app soon.

Data Driven

For a Functional Pumpout Network

Our staff uses Pumpout Nav when we survey pumpout stations. The app lets us collect information on a unit’s condition and quality. Help us collect some of this information by taking a closer look at the pumpout.                              

Find Pumpouts!

When the Time Comes

Pumpout Nav helps you find the nearest operational pumpout. Make sure you have cell service when turning the app on!

Speak up!

Let us know if something isn't right

If a pumpout isn’t accessible or in working condition, users can take a photo and report it through the app. That lets other boaters know by changing the status on the app, and will send us and the marina manager a note. We will follow up with the marina to get it fixed.

How do we help build a stronger network?

The California Delta

Sewage pumpout systems in the often rural California Delta are often septic system-based and differ from those in the more urban areas of Southern California or the San Francisco Bay Area, presenting unique challenges to boaters and marinas. The effectiveness of these systems can have broad impacts on this stunning ecosystem, potentially degrading water quality and increasing nutrients that help invasive species take hold.

Ensuring a strong, consistent network of functioning marinas that boaters can easily access is key to building good sewage disposal habits. To build the capacity of marinas to address issues of aging infrastructure and lack of resources, SFEP is engaging marina owners and staff in a series of meetings to discuss shared challenges and opportunities. Here are some of the resources we’ve found. 

  • Pumpout, Dump station and Floating Restroom Grants from the Division of Boating and Waterways
  • Boating Infrastructure Grants for public agencies to provide transient dockage for recreational vehicles 26 feet or more in length
  • Abandoned vessel grants to remove, reduce and prevent abandoned recreational vessels and marine debris
  • California Wildlife Conservation Board Public Access Program to support projects focused on the protection and development of public access areas and the promotion of hunting and fishing opportunities. More information can be found here.
  • The NOAA Marine Debris Program offers funding that supports prevention and removal of marine debris. More information can be found here. 
  • Meet the state agencies tasked with ecosystem restoration implementation and Delta management – the Sacramento-San Joaquin Delta Conservancy and the Delta Stewardship Council.
