Mississippi's onsite wastewater disposal systems are regulated by the Mississippi State Department of Health (MSDH) through its Division of Onsite Wastewater, under the Mississippi Individual On-Site Wastewater Disposal System Law. Permitting and inspections are conducted by MSDH district offices and county sanitarians covering all 82 counties. Mississippi's soils range from the rich, heavy clay of the Delta region (Bolivar, Sunflower, and Washington counties) to the sandy loam of the Piney Woods in the southeastern part of the state, with the distinctive loess bluffs along the Mississippi River near Vicksburg and Natchez adding yet another soil type. The state's warm, humid climate with over 55 inches of annual rainfall sustains year-round bacterial activity in tanks but also keeps water tables high.
