New Supplies to Secure San Antonio's Water Future

Our city has a well-deserved reputation as a leader in water conservation. But for our community to grow and prosper, new water sources will be needed. Rather than wait for a water shortage (as some communities have done), San Antonio is investing wisely in new water projects to meet future needs.

Projects Already Underway

Regional Carrizo
By the end of 2013, Carrizo Aquifer water will be piped to San Antonio from western Gonzales County, enough to supply 60,000 homes.

Groundwater Desalination
Already under construction in southern Bexar County, the desal project will come on line in 2016 and deliver up to 28,000 acre-feet per year by 2026.

Proposed Future Supplies

Regional Water Supply
In 2011, SAWS requested competitive sealed proposals for delivery of a turn-key water supply of up to 50,000 acre-feet per year by 2018. Project evaluation and selection is expected by the end of 2012.

Expanded Local Carrizo Aquifer
Existing infrastructure and wells in southern Bexar County would be used to produce up to an additional 21,000 acre-feet per year by 2027.
