Regional Brackish Groundwater Deslination (BGD) Systems Deemed Best Option To Resolve Mounting Water Shortages in Lower Rio Grande Valley
A two-year study by the Rio Grande Regional Water Authority and U.S. Bureau of Reclamation with involvement from the Rio Grande Regional Water Planning Group recommends building three regional BGD systems in Cameron, Hidalgo, and Willacy counties to produce 93,000 acre-feet of water per year (AF/yr) at a total cost of $494 million.
Such action is necessary, says the study, to alleviate shortfalls caused by drought, reduced inflows from Mexico into the Rio Grande, population growth, and the impacts of climate change. The 2011 Rio Grande Regional Water Plan – which addresses long-term water supplies and needs – projected that population in Cameron, Willacy, Hidalgo, Starr, Zapata, Jim Hogg, Webb, and Maverick counties will grow from 1.7 million in 2010 to 4 million in 2060 and that water supply shortages will reach a staggering 592,084 AF/yr.
But the supply shortfall projected in the 2011 plan will actually be worse because of the impacts of climate change, according to the recently completed RGRWA and Reclamation basin study, which projects the deficit will grow by 86,438 AF/yr to 678,522 AF/yr.
