Plumbers usually install sewer lines to slope down from inlet to outlet, at 1/8' per foot to 1/4' per foot of linear run of the waste pipe. We don't put the septic tank any deeper than necessary, since we are usually moving effluent from the septic tank to the drainfield also by gravity. The further the tank is located from the building, if the system uses gravity to move sewage, the deeper the tank will be.

If a site has bedrock or large boulders close to the surface, the tank may be located elsewhere Of shape, rocks, obstructions: the location at which the contractor found site conditions suitable to bury the septic tank. Since usually we rely on gravity to move sewage from the building to the septic tank, the tank will be lower than the exiting waste line of the building it serves The depth at which the lowest sewer line leaves the building which the septic tank serves.

The principal factors that determine the actual depth at which a septic tank is likely to be buried (and thus how deep you may have to dig to find the septic tank) at a particular site include: You'll kill the bacteria and destroy the drainfield as well as contaminate the local environment. Watch out: If your concern with septic tank depth is to avoid freezing, DO NOT add antifreeze to a septic system. Septic tanks can be installed pretty much at any depth in the soil.Įven in freezing climates, the septic tank serving an occupied home or even an unoccupied one is unlikely to freeze, partly because of latent heat the bottom of the septic tank receives from the earth and partly because of the heat generated by the bacterial action going on in the septic tank, and mostly from warm wastewater entering from the building served by the septic system.

Here we describe the depth at which septic tanks are installed and we describe several factors that influence the actual depth to which a septic tank (or cesspool or drywell or soak-pit) will be buried.Ī companion article linked-to at the end of this one explains the septic tank depth sketch shown at the top of this page and describes in detail how to find the actual depth of an existing installed septic tank. Septic tank design depth: To what depths are septic tanks or cesspools or seepage pits or drywells commonly buried?ĭo we need to put the septic tank below the frost line to avoid freezing?
