What is needed for Leachfield Sewage Treatment Systems
Risers on the Inlet, Outlet of the tank, Splitter Box(s) and / or, and Distribution Box(s). Lift Station. Inlet and Outlet baffles in septic tank.
Inlet and Outlet Risers: Able to visibly see the plumbing entering into the septic tank and also exiting the tank, as well as visibly see the inlet and outlet baffles.
Inlet and Outlet Baffles: Ensure inlet and outlet baffles are present or replaced. The risers need to be directly above the inlet and outlet baffle to check the liquid levels. If an older tank exists and no lids are present, we still require two (2) lids to see both baffles. (You will need to make openings.) Often times a lid is present but it is actually very large.
Splitter Box and or Distribution Box Riser: Able to see the entire box to view the condition. The plumbing entering into the distribution box and the lines exiting the distribution box must be visible. If the box is deteriorated it should be replaced. Replacing a distribution box can only be done by a registered installer. Each individual splitter box and distribution box will need a riser. If a splitter box is present a split device or cap needs to be present to let the line(s) rest.
Splitter Valve: Able to see inside. If the splitter valve is deteriorated it should be replaced. Replacing a distribution box can only be done by a registered installer. If a splitter valve is present a split device or cap needs to be present to let the line(s) rest
Inspection port on Curtain Drain: Needs to be 8” and able to visibly see the tile(s) inside the inspection port and be able to sample from this port, if necessary.
Observation Ports (If Present): Needs to be 8” and able to visibly see the inside the observation port.
Lift Station: Able to see the entirety of the inside. The plumbing entering into the lift station, the lift pump itself, and the lines exiting be visible for a proper evaluation. If the lift station has deteriorated it should be replaced. Replacing a lift station can only be done by a registered installer.
