Formerly Snohomish Septic, Woodinville Septic, Kingsgate Septic and Evergreen Onsite, we’ve combined to streamline our operations, and we’re excited to reintroduce ourselves as The Septic Group! Continuing to serve Snohomish and King counties, The Septic Group retains the same personnel with the same expertise, superior customer service and competitive pricing. The only difference you’ll notice is our new name and logo. As always, we provide great responsiveness and an enhanced range of services. We look forward to serving you!
