Nueces River Authority outlines 450 MGD desalination project and pipeline plan

The City Council of Corpus Christi made significant strides in addressing the region's water supply challenges during their meeting on August 12, 2025. A key highlight was the approval of a public-private partnership (P3) for a new desalination plant, which aims to provide up to 450 million gallons of water per day. This facility will utilize a reverse osmosis process and is expected to begin delivering water to the Coastal Bend area by 2029.

The council discussed the project's design, financing, and operational plans, emphasizing a 30-year take-or-pay contract with the P3 partner. This agreement ensures that the city will have a guaranteed water supply while allowing for future expansion as demand grows. The initial phase will focus on delivering 100 million gallons per day, with potential to scale up to 450 million gallons as needed.

A significant aspect of the project involves the construction of a six-mile pipeline from Harbor Island to Aransas Pass, which is crucial for transporting the desalinated water. The council is currently navigating the permitting process with various regulatory bodies, including the Texas Commission on Environmental Quality and the U.S. Army Corps of Engineers. They reported progress on securing necessary permits, with some already under technical review.

The council also addressed concerns regarding the cost of desalinated water, which is projected to range between $10 and $15 per thousand gallons. While the exact pricing remains uncertain due to various factors, the council is committed to maintaining affordability for municipal and industrial customers.

In addition to the desalination project, the council discussed the importance of regional partnerships to enhance water supply and management. They expressed a desire to collaborate with neighboring municipalities to ensure a sustainable water future for the Coastal Bend region.

As the project moves forward, the council is focused on finalizing contracts and securing additional commitments from municipalities to ensure the success of this vital water supply initiative. The next steps include detailed design work for the pipeline and continued engagement with potential water customers to solidify demand.
