The City of Corpus Christi has approved a resolution that advances the development of a seawater desalination facility at the Inner Harbor, marking a new phase in the city’s long-term water supply strategy. The decision authorizes the negotiation of a design-build contract with Corpus Christi Desal Partners (CCDP).
CCDP is a joint venture formed by Acciona Agua Corporation and MasTec Industrial Corporation. City staff have been instructed to prepare the proposed contract for formal consideration by elected officials in April 2026.
“This is a significant step forward in securing long-term, reliable water supply for our customers,” said Nicholas Winkelmann, Chief Operating Officer of Corpus Christi Water. “We are pleased to move forward with a highly qualified team committed to delivering this critical infrastructure project.”
Acciona brings extensive international experience in water treatment infrastructure, including the delivery of hundreds of facilities worldwide and numerous seawater reverse osmosis plants. Among its U.S. references is the Tampa Bay Desalination Plant, one of the largest of its kind in the country. MasTec Industrial Corporation contributes broad expertise in complex water and wastewater projects across multiple delivery models and is certified as a minority-controlled company.
According to the city, several foundational elements of the Inner Harbor project are already in place. These include previously issued intake and discharge permits from the Texas Commission on Environmental Quality and the U.S. Army Corps of Engineers, as well as land agreements, power supply arrangements, and financing through the Texas Water Development Board.
If negotiations are completed as planned, the City Council is expected to review the final design-build agreement in April 2026, keeping the Inner Harbor seawater desalination initiative on track.
