McAllen to build $185 million groundwater desalination plant and secure federal grant for water reliability

McAllen Public Utility (MPU) described a major water‑infrastructure initiative during the State of the City address: a planned $185 million groundwater desalination facility at the North Water Treatment Plant, using advanced reverse‑osmosis technology to treat up to 10 million gallons per day, the utility said.

MPU officials told the audience the plant is intended to strengthen the city’s long‑term water supply and resilience amid growing pressures such as aging infrastructure and contaminants. The utility also reported investments including $3.2 million for securing water rights and a $9.6 million grant awarded by the U.S. Bureau of Reclamation to fortify long‑term water reliability.

MPU noted other recent work including emergency power upgrades at its wastewater treatment plant and completion of a smart‑meter replacement project intended to reduce water loss and provide customers with near‑real‑time consumption data. City leaders said these steps are part of a broader resilience strategy that combines treatment, reuse and hazard mitigation funding.

City and utility representatives did not indicate a project completion date in the remarks. Funding sources cited include the federal grant and city allocations; project procurement, environmental review and schedule remain to be announced.
