Southmost Regional Water Auth. (SRWA)


Southmost Regional Water Authority

Brownsville Public Utilities Board (BPUB) is a major partner in the Southmost Regional Water Authority (SRWA), a conservation and reclamation district consisting of six entities in southern Cameron County. When SRWA members were searching for a regional approach to solving the area’s water needs, they decided to construct and operate a regional desalination facility.

The SRWA Brackish Groundwater Treatment Facility, located on FM 511, uses reverse osmosis membrane technology to treat brackish (salty) groundwater and produce drinking water for five SRWA partners. This project provides for an alternative water supply source away from the Rio Grande for the majority of the SRWA partners.

Construction of the desalination plant was completed in 2004, and the plant produces as much as 7.5 million gallons per day (mgd). Additional membrane treatment processes are planned for construction in 2013-14.

In 2015, the SRWA completed improvements to allow the plant to produce 10 mgd.
