About SRWA

Who We Are

The Southmost Regional Water Authority (SRWA) is a conservation and reclamation district made up of six member entities in southern Cameron County, Texas. SRWA was created in 1981 for the purpose of developing water supply strategies for its regional partners.

By 1993, prolonged drought prompted a search for alternative water sources to reduce the region's dependence on the Rio Grande. In 2004, SRWA completed construction of a 7.5 million-gallon-per-day desalination facility. In 2015, the plant added microfiltration pretreatment and expanded its reverse osmosis treatment capacity to 10 million gallons per day.

What We Do

The SRWA facility utilizes reverse osmosis (RO) membrane technology to treat brackish groundwater and provide drinking water for participating entities. By producing an alternate source of water, the plant reduces reliance on the Rio Grande River and helps address drought conditions and water supply issues in Southern Cameron County.

At its current capacity, the plant can save approximately 11,200 acre-feet of surface water diversions per year from the Rio Grande.
