We are Vashon Team Septic, also known as the Septic Sisters. We're here to help island neighbors build and maintain healthy septic systems.

What burning questions do you have about your septic? We’ve compiled some basic Q&As based on what we’ve heard so far. Feel free to contact us if we don’t answer your question here.

Another great resource is King County’s Sanitarian of the Day. Leave a voicemail with your “What if?” questions at 206-477-8177 and they will get back to you with advice within 1-2 business days. You don’t need to tell them your name or location.
