Texas– The city of Corpus Christi has been exploring potential sites for a desalination facility to help diversify its water supplies for drought occurrences. The city has applied to obtain a water quality permit with the Texas Commission on Environmental Quality. The proposed facility would be situated on land off La Quinta Road in Gregory, with a discharge route planned into the La Quinta Channel in Corpus Christi Bay. The desalination plant would not exceed a daily flow average of 19.1 million gallons per day. The proposed facility will output water treated for industrial use. Since the plant will be located near the San Patricio Water Municipal District, the water can be further treated to become drinkable.
According to the Texas Desalination Association, nearly 100 small and intermittent inland desalination facilities across Texas produce 138 million gallons of water per day from the 2.7 billion acre-feet of brackish water in Texas’ aquifers. Brackish water has far less salinity than seawater. The biggest desalination facilities in Texas are the Kay Bailey Hutchinson plant in El Paso, which can produce up to 27.5 million gallons of fresh water daily, and the Southmost Regional Water Authority Desalination Plant, which produces 7.5 million gallons a day for south Texas. According to the Texas Water Development Board, the average cost to produce 1 acre-foot of desalinated water from seawater is projected to range from approximately $800 to about $1,400
