The Wastewater Treatment Plant (WWTP) is responsible for the treatment of wastewater received from the wastewater collection system for discharge into Cibolo creek. The wastewater must be treated to meet strict federal and state limits before being discharged.
Wastewater is pumped to the plant from several offsite lift stations. The wastewater enters the plant at the headworks, which is equipped with two bar screens, one manual and one mechanical. The bar screens remove large objects from the wastewater stream. The wastewater then flows to preliminary treatment which consists of three primary clarifiers, trickling filters, intermediate clarifiers and then it is split equally into three aeration basins.
The air that is pumped in to the aeration basin helps create an environment for bacteria and other organisms (Bugs) to live and thrive which help breakdown the solids.
