The First US City Is on Track to Run Out of Water

Corpus Christi is the eighth-largest city in Texas, a coastal hub of refineries, chemical plants, and deepwater docks – and as of early 2026, its two main drinking water reservoirs were holding less than one-tenth of their combined capacity. That figure alone would rank as a crisis for most cities. What makes Corpus Christi’s situation different is the reason those reservoirs are so depleted, and who else is drinking from them.

The city doesn’t just supply water to its residents. More than half its total water demand comes from the multi-billion dollar chemical plants, refineries, and other industrial facilities operated by some of the biggest companies in the world. That imbalance between industrial thirst and a shrinking natural supply is at the center of what has become the most serious US city water shortage playing out right now in America.

Since August 2024, the city’s 318,000 residents have been unable to water their lawns and have been restricted in their ability to wash boats and cars. And yet, as of early 2026, the reservoirs kept dropping. Residential conservation, it turns out, was never going to be enough.

How a City Built Itself Into a Corner

The roots of this situation stretch back more than a decade, to the period of rapid industrial expansion that followed the shale revolution in the oilfields of Texas. By 2015, a surge of major industrial projects was seeking to build in the area. From 2013 to 2023, the Port of Corpus Christi’s trade value more than doubled, in part as a result of increased fracking and the 2015 loosening of oil-export restrictions. The port is now the nation’s top exporter of crude oil.

In the late 2010s, as the port’s growth attracted water-intensive petrochemical industries to the Coastal Bend, city staff told companies there would be enough water to meet their needs. That promise was made without a plan to deliver on it. According to Inside Climate News, years of industrial expansion added 36 million gallons per day of water demand, growing the region’s total water consumption by 40 percent, with no new sources coming online since 2016.

The single most striking symbol of that miscalculation is a plastics plant on the city’s edge. Gulf Coast Growth Ventures, a facility operated by ExxonMobil and Saudi Arabia, started operations in 2022 and became the largest single water consumer in the Corpus Christi region. According to an industry water analysis published by AXE H2O, Gulf Coast Growth Ventures alone consumes approximately 13.5 million gallons per day – more than all of Corpus Christi’s residents combined.

If reservoirs dry up, Corpus Christi’s wells might be able to keep water flowing to most toilets, sinks, and showers – but not to the multi-billion-dollar complexes operated by energy giants like ExxonMobil, Valero, Occidental Chemical, Citgo, and Flint Hills Resources, which collectively account for more than half of the region’s water consumption. Those companies have not publicly explained how, or if, they will implement steep water cuts.

The Drought That Broke the Models

The Nueces basin has been experiencing widespread drought conditions since late 2021, leading to very low water levels in Choke Canyon Reservoir and Lake Corpus Christi. By early 2026, those two reservoirs – the city’s primary supplies – had fallen to historic lows. According to the City of Corpus Christi’s own Daily Reservoir and Pass-Thru Status Report dated January 12, 2026, the combined capacity of the two reservoirs had reached just 10%, “marking the lowest level these reservoirs have experienced in their history.”

City Manager Peter Zanoni acknowledged at a March 2026 press conference that the city’s models never indicated the reservoirs would get this low. The models didn’t consider the possibility of a drought as severe as the region now faces. “We based it on the last drought-of-record,” Zanoni said. “This is the worst one yet.”

The region’s 2026 water plan, released in January, “explicitly recognized that, in the event of a repeat of the drought of record, the City of Corpus Christi was already facing an immediate shortage.” Officials added that such a shortage might increase if a new drought of record were to occur – which is exactly what happened.

More than 95 percent of Corpus Christi’s drinking water comes from surface reservoirs that have simply stopped refilling. As a result, the city has had to draw more water from the Colorado River and Lake Texana, which as of March 2026 were supplying about 73 percent of the city’s water. That’s an enormous burden to place on backup sources that were never designed to carry the full load.

What a US City Water Shortage Emergency Actually Triggers

Under the City of Corpus Christi’s Drought Contingency Plan, a “Level 1 Water Emergency” is triggered when the city reaches 180 days from when total water supply is not enough to meet total water demand. If a Level 1 emergency is declared, all customers of the city’s regional water system would be required to cut use by 25 percent.

Without significant rainfall, the city’s government could be forced to declare that water emergency as soon as late 2026. This would require households to limit their water use to 6,000 gallons per month – about two-thirds of the average U.S. household’s normal consumption.

For residents, that’s a painful adjustment. For industry, it could mean something far more disruptive. Companies that own refineries in Corpus Christi say they are working to secure alternative water sources to maintain operations and prevent a shortage of gasoline and jet fuel in Texas and beyond. Flint Hills Resources operates two refineries processing up to 350,000 barrels of crude oil per day and has been among those seeking alternatives. Kara Rivas, a spokesperson for Flint Hills Resources, warned at a City Council meeting: “This would force the shutdown of at least some aspects of our operations.”

Brooke Paup, chair of the Texas Commission on Environmental Quality, put it plainly during a speaking event at the University of Texas in April 2026: “Corpus Christi is running out of water.”

The Desalination Plant That Wasn’t Built

The most obvious long-term solution was a seawater desalination plant – a facility that strips salt from ocean water to produce drinkable supply. The city proposed one years ago. Corpus Christi proposed an ambitious seawater desalination plant capable of producing 30 million gallons of drinking water per day, pitched as a “drought-resistant” solution that could supply both residents and the region’s growing industrial base.

It was never built. The City Council voted in September 2025 to cancel the project after costs escalated and environmental concerns intensified over the discharge of highly concentrated saltwater into Corpus Christi Bay. Critics warned the process could increase salinity levels and create “dead zones” potentially harming the sensitive coastal ecosystem. The city had previously secured state loan approvals of $211 million and had sought an additional $535 million in low-interest state loans for the project, according to earlier city council documents reported by the Corpus Christi Caller Times.

In June 2026, after a roughly 15-hour meeting, the City Council voted 7-2 to delay a decision on reviving the nearly $1 billion desalination plant – leaving the city’s signature long-term fix unresolved. A sharply divided council then declined to apply for a federal grant to help build a proposed $978.8 million water treatment project, with council members trading insults and accusations on their way to a 5-4 vote.

Water resources engineer Kenneth Dees put it plainly in a 2026 assessment reported by the Texas Tribune: “We’re not running out of water,” Dees said. “We’re running out of cheap water.”

The Stopgaps Buying Time

With no large-scale permanent solution in place, the city has turned to a range of emergency measures. Nueces River groundwater wells already supply about 12 million gallons per day, a reclaimed-water project is due to deliver its first 1 million gallons per day in October 2026, and the city is weighing buying water from a privately owned desalination plant operated by Corpus Christi Polymers.

The city is also pursuing permits to install wells in the Evangeline aquifer located to its north, to extract as much as 24 million gallons per day, starting as early as November 2026. Neighboring communities are concerned that Corpus Christi’s pumping could deplete their own groundwater supplies, and have filed paperwork seeking to block the city’s permit request.

Several companies, including Valero and Flint Hills Resources, have agreed to use reclaimed water at their facilities in place of drinking-quality water they don’t actually need. The pipeline infrastructure for this switch is expected to be completed in June 2026, with an initial 1 million gallons per day available in October and up to 16 million gallons per day when fully operational.

On the private desalination front, the Corpus Christi City Council voted 6-2 to begin preliminary talks with AXE H2O, a Houston-based company seeking to build a plant that could produce 150 million gallons of drinking water per day. Before breaking ground, the city would have to agree to purchase a significant volume of water from the plant for at least 30 years. No deal has been finalized.

Rain Helps – But Doesn’t Solve It

A run of rainfall in mid-2026 offered some relief. Lake Corpus Christi’s capacity jumped from around 9 percent in April to 30 percent by June 2026, according to the Texas Tribune. The rains, however, missed Choke Canyon, the city’s biggest reservoir, which has hovered around 8 percent capacity for several months. Lake Texana, the third reservoir the city uses, rebounded from nearly 50 percent capacity in April to 100 percent, although it is known for filling up and depleting quickly.

Corpus Christi received welcome news in June when its projected water emergency was delayed to September 2027 after recent rains boosted some of the region’s reservoirs. The reprieve buys time. It does not refill the lakes.

Even groundwater supplies are not immune to drought. Without sufficient rainfall, aquifers are not replenished, meaning water levels will continue to drop and deeper wells will be needed to reach the diminishing supply.

What This Means for Residents – and the Country

Corpus Christi is not alone. Across parts of south, west, and central Texas, decades of rapid development and recurring drought have stretched water supplies to their limits. Official projections show some places running dry within 10 to 20 years, with few new sources of water to turn to.

The difference is that Corpus Christi is already here. “Corpus Christi is running out of water,” the chair of the Texas Commission on Environmental Quality said publicly in April 2026. The city supplies water to 500,000 to 600,000 people across seven counties, and the industrial infrastructure it supports fuels energy supply chains that reach far beyond Texas.

The core problem hasn’t changed: a heavily industrial city built its growth on the promise of water that was never fully secured. Drought intensified what was already a structural gap. And the solutions that could have been in place by now – a desalination plant, diversified aquifer access, reclaimed water infrastructure – are still months or years away from delivering meaningful volume.

What Happens Next

Lawns across Corpus Christi have been dead since 2024. Household water allocations may soon be capped by formal emergency order. The 25 percent cuts that would accompany a Level 1 declaration would fall on industries that have never faced mandatory conservation in the city’s history, which is why the stakes extend well beyond the city limits.

The refineries and chemical plants that drive Corpus Christi’s economy also supply gasoline, jet fuel, and petrochemicals to markets across the American South and Southwest. A water shortage severe enough to force operational cutbacks at Flint Hills Resources, which processes up to 350,000 barrels of crude per day, or at ExxonMobil’s Gulf Coast Growth Ventures facility, would send ripple effects through fuel supply chains that reach from Dallas-Fort Worth to San Antonio to the Gulf Coast export terminals.

The city’s council is still debating whether to revive the $978.8 million desalination plant, still evaluating private alternatives, and still waiting for groundwater permits and reclaimed-water pipelines to come online. The September 2027 emergency projection assumes the recent rains hold and new water sources arrive on schedule. That is, at this stage, an optimistic assumption – not a guarantee.
