Primary and secondary treatments remove about 85% to 95% of pollutants from the wastewater before the treated wastewater is disinfected and discharged into local waterways. Sludge, the byproduct of the treatment process, is digested for stabilization and is then dewatered for easier handling.
If washing machines, dishwashers, and garbage disposals are used, the amount of sludge will increase and the septic tank will require frequent cleaning. WASTEWATER DISPOSAL BY SOIL ABSORPTION.

The wastewater effluent is absorbed by soil particles and moves both horizontally and vertically through the soil pores.
