However, many people who live in rural areas cannot utilize a conventional system.

By the time the wastewater reenters the groundwater supply, it is relatively free of pollutants. As the effluent trickles out of the perforations in the lines, soil borne microorganisms, along with the natural filtering properties of the soil itself, continue the treatment process. The wastewater, also called effluent, leaves the septic tank and flows into the field lines.
In the septic tank, solids settle down to the tank bottom, and the wastewater is partially treated by anaerobic microorganisms within the tank. Sewage generated within the home flows into the septic tank. Traditionally, rural homeowners have used simple wastewater treatment systems consisting of a concrete septic tank and a connected network of perforated pipes, or field lines, buried in the neighboring soil. Continuing education classes are offered at the University campus each year. The center is a member in a partnership that includes many federal, state, and local agencies, including the Alabama Onsite Wastewater Association, the Tombigbee Resource Conservation and Development Council, the Alabama Department of Public Health, the Alabama Onsite Wastewater Board,, the Alabama Soil and Water Conservation Committee, and the Sumter County Soil and Water Conservation District. The center was established with funding from the United States Environmental Protection Agency through the Alabama Department of Environmental Management, and by donations from the University of West Alabama and other contributors. The organization is dedicated to expanding public awareness of water quality issues, with a particular emphasis on wastewater management. The West Alabama Onsite Wastewater Training Center (WAOWTC) was established in 1997 because of a growing need for education in the rapidly changing wastewater field.
