Between October 2020 and February 2021 the California Boating Clean and Green Program (BCGP), San Francisco Estuary Partnership (SFEP), and TBF (project partners) implemented the statewide Boater Sewage Disposal Survey (survey). The survey aimed to collect information on California boaters’ sewage disposal norms and preferences. Project partners sought to find out how boaters currently dispose of boat sewage, if they were satisfied with their chosen method, if they preferred another method, and how they search for information about sewage pumpout and dump stations and clean boating resources. Survey findings were analyzed and a report was produced to summarize boaters’ preferred sewage disposal method and help partners gain insight into how disposal needs are currently being met. Analysis of this information can inform future outreach programs that serve the boating community and help protect the shared resource of California’s waterways.
