Description / Abstract:

These requirements cover single and multiple compartment, bituminous-coated metal septic tanks for use in residential sewage systems.

The minimum liquid capacity of septic tanks covered by these requirements is 500 gallons (1985 L).

For the purpose of these requirements, a residential septic tank is an enclosed, watertight, sewage-settling tank intended to retain the solids in immediate contact with the sewage flowing through the tank for a period of time to secure satisfactory decomposition of settled solids by biochemical action.

The liquid capacity is the capacity of the tank below the bottom of the outlet when the tank is level.
