Groundwater: Cheaper, Faster, Cleaner

Groundwater $4/1,000 gallons
Desal $8/1,000 gallons
NO Environmental Waste from groundwater
The Evangeline Groundwater Project is a new, low-cost, drought-proof source of water supply for municipalities and businesses to support continuing economic development and provide water security to residents and industry in the Coastal Bend region.

The Project will supply up to 28,000 acre-feet of permitted groundwater, per year (25 MGD), from a 23,000-acre tract of land in San Patricio County north of Corpus Christi over a sweet spot of the Gulf Coast Aquifer, with superior production quantity and quality. The Project’s groundwater could be delivered to multiple locations in the region within 18 months or less.

The management team leading the Project has a track record of over 20 years of transparent, collaborative and successful large scale, public water supply projects bringing groundwater solutions to municipalities in Texas.

Evangeline water is 40% cheaper than desal.

Evangeline water can quickly be delivered to customers.

Evangeline water is drinking water quality without the environment waste from desal.


Is Evangeline groundwater drought-proof?
Yes. The Gulf Coast Aquifer does not react to droughts like surface water – the aquifer has water stored in its many layers, which has accumulated over millions of years.

This water does not evaporate like surface water in lakes and reservoirs and is available for production in wet years and dry years. The Texas Water Development Board has conducted a study in which they estimated that there are 51,000,000 acre-feet of water stored beneath San Patricio County in the Gulf Coast Aquifer. The Gulf Coast Aquifer is recharged through rainfall, drainage from rivers and movement between neighboring aquifer systems.

Using the TWDB’s most conservative production yield – and disregarding all recharge to the aquifer – there are 292 years of water supply from the Gulf Coast Aquifer in San Patricio County (including the Evangeline project), and over 877 years using TWDB’s higher projected recovery rate.

Is Evangeline groundwater cheaper than other alternatives?
Yes. The Coastal Bend Regional Water Planning Group recently presented unbiased, third-party apples-to-apples cost estimates for water supply projects in the region, including Evangeline groundwater and various seawater desalination projects. The Planning Group followed Texas Water Development Board guidelines to estimate costs to produce and deliver new water supplies from the Evangeline Project and the seawater desalination water projects proposed by the City of Corpus Christi, the City of Ingleside and the Port of Corpus Christi.

At Planning Group meetings on November 14, 2019, and January 16, 2020, the Planning Group’s consultant presented its estimates for the cost of water from these projects, a summary of which is available [Cost Comparison Guide]. We think the Planning Group’s analysis bears great weight as a comparison of the relative costs of these projects.

Has groundwater ever been used as a significant water supply in the region?
Yes. Before the Lake Corpus Christi and Choke Canyon Reservoir projects, the region relied exclusively on groundwater from the Gulf Coast Aquifer for its entire water supply. Even after the reservoirs were completed, from the 1950s through the 1990s the City of Corpus Christi relied on wells it operated in this same aquifer to produce groundwater to supply up to 15% of the region’s water demands.

The City of Sinton relies on groundwater for its entire water supply and the cities of Kingsville, El Paso, Lubbock, Abilene, Amarillo, and San Antonio rely on groundwater for a majority of their water supply.

Groundwater is a reliable, sustainable water supply source for the Coastal Bend.

Is Evangeline Groundwater drinking water quality?
Yes. Evangeline groundwater, without any treatment, meets the same state and federal water quality standards as the treated water that the City of Corpus Christi and San Patricio Municipal Water District deliver to your taps at home.
Could Evangeline water be transported through the Mary Rhodes Pipeline?
Yes. The Texas Commission on Environmental Quality rules requires that any new water source proposed for inclusion in an existing pipeline must first pass their tests to ensure compatibility with the pipeline and the water currently being transported through the pipeline.

Evangeline has had experts test its water under the TCEQ protocol, and the Evangeline groundwater meets all TCEQ requirements, so the City of Corpus Christi could transport Evangeline groundwater through the Mary Rhodes Pipeline.
