Corpus Christi voters approved a charter amendment Tuesday that will eliminate a program allowing large industrial water customers to pay an annual fee in exchange for exemptions from drought surcharges, changing how some of the city's largest water users contribute to conservation efforts during water shortages.
Proposition B passed with 68.46% of the vote, receiving 56,876 votes in favor and 26,203 against, according to unofficial Nueces County election results. All 53 vote centers had reported as of early Wednesday.
The measure requires large industrial water customers to pay drought surcharges during specified drought stages rather than participate in the city's existing exemption program.
The decision comes as Corpus Christi continues to confront water supply challenges and works to develop additional sources to meet municipal and industrial demand.
How the industrial exemption worked
Under the city's existing program, qualifying industrial water customers could pay a fee to avoid drought-related surcharges. The arrangement provided the city with a dedicated revenue stream for developing additional water supplies while offering participating businesses greater predictability in their water costs.
According to the Corpus Christi Caller-Times, the exemption fees generate approximately $6 million annually for new water supply projects.
The city has not yet imposed drought surcharges, meaning the program has primarily functioned as a funding mechanism rather than an alternative to charges that industrial customers were already paying.
Proposition B changes that structure by ending the exemption and requiring qualifying industrial customers to pay applicable drought surcharges when the specified conditions are met.
The measure covers industrial users, large data centers and large-scale power customers consuming at least 100,000 gallons of water per day.
Under the amendment, surcharge rates would apply to water consumption above a defined monthly threshold, with minimum charges of $3 per 1,000 gallons during Stage 2 drought restrictions, $6 during Stage 3 and $12 during a water emergency.
For large industrial operations, those charges could become significant during extended drought conditions, depending on water consumption and the restrictions in effect.
A transition that could take years
Although voters approved the amendment, the exemption program will not necessarily end immediately.
According to the City of Corpus Christi's election information, terminating existing arrangements involves a notice period that could extend up to five years.
That transition creates uncertainty about when individual industrial customers will begin paying surcharges under the new system.
It also raises a financial question for the city. The existing exemption program produces approximately $6 million annually for water supply development. Ending it could affect that revenue stream, while future drought-surcharge collections would depend on drought conditions and industrial water consumption.
Because Corpus Christi has not previously imposed the surcharges, the amount of revenue the new system might generate remains uncertain.
What the vote means for water planning
Proposition B reflects a broader challenge facing water-stressed communities with large industrial customers: determining how to allocate the financial burden of securing new supplies while encouraging conservation during shortages.
Industrial facilities can represent substantial portions of a municipal water system's demand, making their consumption patterns important to long-term capacity planning. Drought pricing can encourage reductions in discretionary water use, but it also introduces additional costs for businesses that depend on consistent water supplies.
For Corpus Christi, the amendment shifts the city's approach from collecting predictable exemption fees toward requiring qualifying industrial customers to pay drought-related charges when applicable.
The immediate implications will depend on how the city implements the amendment, manages the transition from existing agreements and addresses the potential loss of dedicated water supply development revenue.
Voters have settled the policy question. City officials must now determine how to put the new requirements into practice while continuing to finance the water infrastructure needed to support Corpus Christi's residential and industrial customers.
