After primary treatment in the septic tank, liquid effluent flows to the lagoon through a watertight pipe and discharges near the center of the lagoon bottom. Residential waste stabilization lagoons are commonly used for onsite sewage treatment in Missouri in low-population areas where soils are not suited for conventional absorption field systems. For at-risk areas, connecting to an adequate public sewer system is the most satisfactory and trouble-free method of disposing of domestic sewage from private residences.
