How to find the septic tank: to start your outside search, locate point at which the main sewer line leaves the building. The main waste line exit point at a building often points to the direction and sometimes right to the septic tank. But there are exceptions, as we explain here. Septic tank location guide: this document provides suggestions and procedures for finding a septic tank.

Particularly for sites where there are not obvious outside clues, this is where to begin your search for the septic tank - inside the building, following its drain lines.
Outside Septic Waste Line Vents Can Point to the Septic Tank Location
At some buildings you may see a 4" to 6" diameter vertical pipe rising from the soil near the house wall, often with a mushroom-shaped cap on top, or you may see such a pipe protruding horizontally through the building foundation wall and extending for a few inches, covered by a cap or by a perforated cover. Sewer line vents are often vents installed on the main waste line.
Finding one of these sewer line vents in a building wall or protruding from the soil outside is another way to spot where the main waste line is exiting the building.
