What is the project?
 

The Laguna Madre Water District is proposing the development of a Seawater Reverse Osmosis (SWRO) desalination facility. The project would include the construction of a seawater intake structure, upgrades to existing water treatment infrastructure, and the installation of water purification systems. If completed, the facility would be capable of producing up to 5 million gallons of treated water per day, supplementing existing water supplies.

Why is it being considered?
 

The region currently relies heavily on the Rio Grande and the Falcon and Amistad Reservoir System, both of which have experienced reduced water levels due to drought and overallocation. Climate variability, population growth, and agricultural demand have contributed to concerns about long-term water availability. The proposed desalination facility is being considered as an alternative water source to help diversify supply and address potential future shortages.

What is the cost?

A proposed tax bond measure of $59 million would fund the final phase of the desalination facility’s construction and related infrastructure. If approved by voters, the bond would cover costs associated with building the desalination facility. The estimated impact on taxpayers is approximately $0.07 per $100 of taxable property value. For example, a property valued at $200,000 would see an estimated annual increase of $140 in taxes.

Will the Seawater Desalination Plant Impact Our Utility Rates?
 

Based on our current estimates, utility bills are expected to increase by approximately 25% to 35% once the facility becomes operational in 2028. This increase is due to the plant’s operating costs, which will be incorporated into overall utility rates. We are committed to keeping rates as manageable as possible. One of the ways we plan to do this is by balancing water production between the new seawater desalination plant and our existing facility, which has lower treatment costs. This strategy allows us to use the most cost-effective sources to meet demand. The preliminary design of the desalination plant is now complete, and we are currently in the piloting and environmental permitting phases. These efforts will provide the detailed data needed for final design and more accurate cost estimates. We will continue to keep the public informed as the project progresses.
