Wastewater Treatment

Program Description


The purpose and function of the Wastewater Treatment Department is to receive and treat the spent water from a community containing the wastes from domestic, industrial, or commercial use, as well as the surface water runoff and groundwater which may enter the system through infiltration.

The Granbury Wastewater Treatment Plant is an activated sludge process. The activated sludge process is an aerobic biological process in which microorganisms grow by using oxidizable material in the wastewater as food. The microorganisms are recycled to the treatment phase in order to increase the rate of reaction. Laboratory personnel collect and analyze wastewater samples daily to verify compliance with state and federal requirements.
