Established on October 1, 1994 to operate and manage the existing 1.1 mgd Larremore Street Plant and a 1.5 mgd F.M. 20 Plant, completed in February 1999, under contract for the City of Lockhart. The plants supply a combined treatment capacity of 2.6 mgd to provide environmentally-responsible wastewater treatment service within the city limits and meet future growth needs.
The F.M. 20 Plant is an approved site for acceptance and treatment of septic tank waste. It utilizes an innovative “carousel activated sludge process” to treat wastewater, simplifying plant operation and maintenance. Ultraviolet (UV) light disinfection is also used in place of chlorine.
An on-site laboratory conducts daily sample testing to ensure treated effluent meets all state and federal guidelines. Furthermore, “biomonitoring” tests are performed on two aquatic species – a microscopic crustacean and the fathead minnow – to ensure that aquatic life and the environment will not be harmed by treated wastewater effluent returned to the Guadalupe River.
