Septic Systems/POWTS

Conventional System Diagram - Source EPAActivities relating to the installation or repair of septic systems requires the owner of the property to obtain a Washington County Sanitary Permit. A Master Plumber or Master Plumber-Restricted Sewer is the responsible party for obtaining the permit, and the installation and/or repair of the system. In order to apply for a sanitary permit submit an application, site plan, a site evaluation and a system design. For certain POWTS, state approval is needed before applying for the County sanitary permit. A Washington County Land Use Inspector will ensure that the POWTS is installed in compliance with state codes through a series of inspections.
