The San Jacinto River Authority (SJRA) is a public entity created by the Texas Legislature whose mission is to develop, conserve, and protect the water resources of the San Jacinto River basin. Covering all or part of seven counties, the organization’s jurisdiction includes the entire San Jacinto River watershed, excluding Harris County. The SJRA is one of two dozen river authorities in the State of Texas, and like other river authorities, its primary purpose is to implement long-term, regional projects related to water supply and wastewater treatment.

The SJRA boundaries include the entire watershed of the San Jacinto River and its tributaries excluding Harris County. This includes all of Montgomery County and parts of Walker, Waller, San Jacinto, Grimes, Fort Bend, and Liberty Counties. SJRA serves many customers in the Houston area and is authorized to operate in East Harris County through an agreement with the City of Houston, which allows the SJRA to operate east of the San Jacinto River.

SJRA receives no money from the state, nor does it collect any type of taxes. Income is primarily derived from the sale and distribution of water and treatment of wastewater. This revenue covers the cost of operation and maintenance as well as outstanding debt. Revenue bonds are sold to finance projects.
