What is needed for Aeration Sewage Treatment Systems


Risers on the Inlet, Outlet, Aeration Motor, and Upflow filter (if present).  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 actually present but it is very large.


Aeration Motor (Prior to 2007):  Riser above aeration motor and motor should run 10 – 15 minutes for every half hour (30 minutes). Effluent should be clear when sampling from the outlet of septic tank. If the effluent is dark, grey, or cloudy, that indicates the aeration motor is not running enough or properly.


Aeration Motor (After 2007): Requires an EPA NPDES permit for discharge. Riser above motor. Follow manufacturer guidelines. These systems need a service contract.


Upflow Filter (If Present): Able to visibly see the gravel inside the upflow filter with minimal (liquid) present
