Texas currently has an estimated total municipal desalination capacity of about 123 million gallons per day (about 137,760 acre-feet per year) which includes 73 million gallons per day (about 81,760 acre-feet per year) of brackish groundwater desalination and 50 million gallons per day (about 56,000 acre-feet per year) of brackish surface water desalination.

In addition to municipal desalination, industrial desalination capacity in the state is estimated to be about 60 to 100 million gallons per day (about 67,000 to 112,000 acre-feet per year) mainly in the power and semi-conductor industries. (Source: TWDB, 2005)
The largest inland municipal desalination plant in Texas, the Kay Bailey Hutchison desalination plant in El Paso, has a design capacity of approximately 27.5 million gallons per day (30,800 acre-feet per year) and went into production in August 2007.
Texas does not yet have a seawater desalination plant. However, on May 14, 2011, voters in Laguna Madre Water District approved a bond proposition to build a 1-million-gallon-per-day seawater desalination plant on South Padre Island.
