Ferric Sulfate Chemical for Water Treatment and Wastewater Treatment Operations

The City of Granbury currently operates one Water Treatment Plant, located at 1420 East Pearl Street, Granbury, Texas 76048. The Water Treatment Plant is responsible for producing safe, high-quality drinking water in compliance with applicable state and federal health standards. The City of Granbury's new Water Treatment Plant began operations in October 2017 and utilizes microfiltration and reverse osmosis technology. The facility expanded the City's treated surface water capacity by more than 500 percent and replaced the former water treatment plant. The facility supports the City's ongoing efforts to provide reliable and high-quality drinking water to the community. The City also operates two wastewater treatment plants, the South Wastewater Treatment Plant and the East Wastewater Treatment Plant. The East Wastewater Treatment Plant, located at 3121 Old Granbury Road, Granbury, Texas, began operations in the summer of 2026 and is currently the City's only wastewater treatment facility utilizing ferric sulfate as part of its treatment process. The purpose and function of the City's Wastewater Treatment Department is to receive and treat wastewater generated by the community, including wastes from residential, industrial, and commercial activities, as well as surface water runoff and groundwater that may enter the wastewater collection system through infiltration. The City's wastewater treatment process utilizes an activated sludge process, which is an aerobic biological treatment process in which microorganisms grow by utilizing oxidizable materials in wastewater as a food source. These microorganisms are recycled back into the treatment process to increase treatment efficiency and reaction rates. City laboratory personnel collect and analyze wastewater samples daily to monitor treatment performance and verify compliance with applicable state and federal regulatory requirements. The reliable supply and availability of ferric sulfate are essential to the continued operation of the East Wastewater Treatment Plant and the City's ability to maintain effective treatment processes and regulatory compliance.
