In the late 1990’s, Schertz supplied water to the community through the operation of a couple of Edwards Aquifer wells. While this system was mostly sufficient for current customers, city leadership knew the community would continue to grow and they desired to secure a long-term reliable water supply for Schertz over the next 50 years. They also believed that ownership of the water provided to the community would give the city more oversight as to the future of water in the area. In December of 1998, Schertz came together with Seguin to form the Schertz/Seguin Local Government Corporation (SSLGC) as a non-profit corporation of the State of Texas for the purpose of providing safe and reliable wholesale potable water to retail municipal customers.
Twenty years later, SSLGC provides groundwater from the Carrizo-Wilcox Aquifer in northwest Gonzales County to the cities of Schertz and Seguin. They own and operate twelve groundwater supply wells, designed and constructed to municipal drinking water standards, and an associated thirty-five million gallon per day groundwater treatment facility in Gonzales County. SSLGC transports water from the treatment facility in Gonzales County to its customers through a water transmission pipeline network traversing over forty miles. SSLGC has 15.1 million gallons of water storage facilities and 15 high-service pumps throughout the water system to deliver water to customers.
