District
East Central Special Utility District (ECSUD) originated as the East Central Water Supply Corporation, a rural water supply organization established in April 1967. In 2005, it transitioned into a Special Utility District. The organization was initially formed to provide water for agricultural and domestic use to residents in rural areas east of San Antonio, Texas.
ECSUD is authorized by the Public Utility Commission of Texas and operates under Certificate of Convenience and Necessity (CCN) No. 10655, allowing it to provide water utility services within its defined service area.
The District serves portions of Bexar, Wilson, and Guadalupe Counties, with its jurisdiction generally located east of San Antonio. ECSUD’s boundaries are roughly defined by Interstate Highway 10 to the north, Church Road near New Berlin and part of the Bexar/Wilson County line to the east, U.S. Highway 181 to the south, and Foster Road to the west.
As of December 2023, ECSUD serves approximately 27,000 residents through 9,000 service connections. The service area has experienced steady residential growth, especially in Bexar County, resulting in increasingly dense permanent residential communities.
ECSUD’s water supply is sourced through contractual agreements with the Canyon Regional Water Authority (supplying from the north) and the San Antonio Water System (supplying from the west). To ensure adequate water pressure, reliable disinfection, and consistent service delivery, the District operates booster pump stations equipped with ground storage tanks throughout the system.
