Sewage treatment is the process of removing contaminants from wastewater and household sewage water. Click here for our range of sewage treatment plants. It includes physical, biological and sometimes chemical processes to remove pollutants. Sewage treatment is the process of removing contaminants from municipal wastewater, containing mainly household sewage plus some industrial wastewater. ... If the sewer system is a combined sewer then it will also carry urban runoff (stormwater) to the sewage treatment plant. The major aim of wastewater treatment is to remove as much of the suspended solids as possible before the remaining water, called effluent, is discharged back to the environment. As solid material decays, it uses up oxygen, which is needed by the plants and animals living in the water.
