Expanded Local Carrizo

Expanded Local Carrizo

New Project Could Further Diversify S.A.'s Water Supply Portfolio

Expanded Local Carrizo is a potential new project in southeastern Bexar County that could yield an additional 21,000 acre-feet* of drinking water by 2026.

Expanded Local Carrizo would develop additional Carrizo Aquifer wells in southern Bexar County close to the SAWS H2Oaks Center facility. SAWS already has experience in designing, building and operating projects that produce freshwater from the Carrizo Aquifer via the Regional Carrizo project.

Proposed Timeline & Estimated Costs

This project could be constructed in three phases starting in 2017 with subsequent phases scheduled for 2022 and 2026 – each phase adding 7,000 acre-feet for a total of 21,000 acre-feet. Expanded Carrizo Aquifer water would be treated at the Aquifer Storage & Recovery facility.

Preliminary estimated capital costs for the project are $34 million.

* An acre-foot of water is equivalent to 325,851 gallons.
