Septic Tank
Cross Section
- The proper sized septic tank (or larger) as specified in the Sewage Disposal Permit must be installed as level as possible.
- The septic tank must have baffles at both ends.
- The cover on the inlet end of the septic tank must be fitted with an inspection port that is to be constructed of 4 inch or larger solid pipe. This inspection port must have a watertight cover and may be flush with the ground surface or may extend above the ground surface a minimum of 8 inches.
- A minimum of one foot of fill should be placed over the septic tank.
- If the septic tank will be buried 3 feet or more below the surface, a watertight manhole, with a minimum diameter of 18 inches, extending to the surface, with a watertight cover, must be constructed over the center access port of the septic tank. In this instance, the inspection port will not be required.
- Four-inch Schedule 40 solid pipe is required to carry sewage from the house to the septic tank.
- A minimum of 5 feet of four-inch schedule 40 pipe is required from the septic tank to the drain field, Soil should be placed carefully and packed around the 4 inch pipe from the septic tank to the drain field to reduce the possibility of pipe sag or breakage. Schedule 40 pipe will reduce the possibility of pipe sag or breakage.
- If there is no built in gasket in the septic tank inlet and outlet, a quick setting, non-shrinking grouting material should be used. Cement shrinks and cracks and therefore does not do a good job.
