Water Treatment Plants

Austin Water currently has three water treatment plants which draw water from the Colorado River and treat it to drinking water quality. After water is pumped from the river into the plants, it goes through several treatment steps including screening, disinfection, coagulation, flocculation, sedimentation, and filtration to ensure that citizens are provided with clean and safe water.  The process takes about 6 to 10 hours to complete.

Wastewater Treatment and Biosolids Plants

Austin Water has two major wastewater treatment plants. The plants receive wastewater flow from Austin Water's sanitary sewer collection system and treat it before returning it to the Colorado River. Austin Water's biosolids facility, Hornsby Bend, receives sludge generated by the treatment processes at the wastewater plants and uses it to create compost for land application and public sales.
