Corpus Christi credit outlook turns negative as city scrambles to execute alternative water portfolio

Corpus Christi credit outlook turns negative as city scrambles to execute alternative water portfolioWith combined reservoir levels plunging to 7.8%, Fitch Ratings has revised the city's General Obligation debt outlook to negative, citing the urgent need to bring new water supplies online within the next 12 to 24 months.

Fitch Ratings affirmed the city's AA rating but shifted its GO debt outlook from stable to negative due to water supply risks.

The city is rapidly expanding groundwater operations, with the Western well field expected to reach 14 MGD capacity this week.

Industrial wastewater reuse projects with Valero and Flint Hills Resources are advancing to maximize the 16 MGD available from city plants.

A long-term desalination partnership with the Nueces River Authority is facing scrutiny following whistleblower allegations regarding reservation fees.

The City of Corpus Christi is facing mounting financial pressure to deliver on its alternative water supply projects as extreme drought cripples its traditional surface water sources. During an April 14, 2026, meeting, City Manager Peter Zanoni briefed the City Council that Fitch Ratings has revised the city's General Obligation (GO) debt outlook from stable to negative, despite affirming its high-grade AA rating. A representative from Specialized Public Finance, the city's financial advisor, noted that the outlook shift is not an indictment of the city's financial management, but directly reflects the urgent need for additional water supply. Fitch indicated the outlook could be revised back to stable if the city successfully brings new water solutions online within the next 12 to 24 months. Moody's and S&P are also currently reviewing the city's credit profile. The urgency is underscored by critically low surface water levels. Director of Water Systems Wesley Netman reported that the combined capacity of Lake Corpus Christi and Choke Canyon has dropped to just 7.8%. To satisfy rating agencies and avert a supply crisis following the previous cancellation of an Inner Harbor desalination plant, the city is rapidly executing a portfolio of groundwater and wastewater reuse projects. Netman reported that the city's Eastern well field is currently averaging 3.6 million gallons per day (MGD). By the end of the week, the Western well field will have seven wells operational, producing a combined 14 MGD. Additionally, a contract with Aquila was issued on April 13 to deliver 3.9 MGD within 11 months, eventually scaling to 21.3 MGD. Progress is also continuing on the Evangeline Groundwater Project, where Pape Dawson has completed 60% of the design deliverables and Garney Construction has mobilized to the site with initial deliveries of HDPE pipe. A preliminary administrative hearing for the project's permits is scheduled for April 28. On the wastewater reuse front, the city is working closely with industrial users to offset potable demand. Flint Hills Resources is targeting an August connection at the Allison wastewater treatment facility, while Valero expects to complete a pipeline connection to the Greenwood plant by the end of the year. To support these flows, the city is constructing a 10-million-gallon ground storage tank at Greenwood. Netman noted that once these refinery projects are online, the city will have effectively tapped out the 16 MGD of reuse capacity available from the Greenwood and Oso plants. While the city executes its short-term portfolio, a long-term desalination prospect has encountered turbulence. Zanoni briefed the council on recent whistleblower allegations at the Nueces River Authority (NRA), the state agency managing a planned Harbor Island desalination facility. Corpus Christi previously paid the NRA a $2.7 million reservation fee to secure 50 MGD of future water. The allegations suggest the NRA's executive leadership may have overstated the population figures and reservation commitments of other participating entities. Zanoni and the city's legal counsel determined that Corpus Christi currently faces no financial exposure regarding its $2.7 million payment, though the allegations pose a reputational risk to the project's viability. The NRA board held a special meeting earlier in the day to hire an independent San Antonio law firm to investigate the claims, and city officials are awaiting the findings before taking any further action.
