City councils in San Marcos, Kyle, and Buda voted on Oct. 20 to issue contract revenue bonds for the Carrizo Expansion Program. The move secures financing for a regional water project that will increase supply capacity for all three communities.
The expansion, managed by the Alliance Regional Water Authority, involves drilling seven new wells in the Carrizo-Wilcox Aquifer. According to agenda documents, the project also includes building a water treatment plant expansion, installing booster pump stations, and upgrading raw water infrastructure. Design work for the initiative began in 2024.
The bond issuances are structured to match the specific water volume each city will receive. San Marcos will gain 2,917 acre-feet annually, equivalent to roughly 2.6 million gallons per day. Kyle is set to receive 2,292 acre-feet per year, or about 2 million gallons daily. Buda will add 413 acre-feet annually, representing approximately 368,660 gallons per day.
The Alliance Regional Water Authority board signed contracts for key components of the project in early August. The Guadalupe-Blanco River Authority is expected to cover the cost difference between the total project expenses and the member shares. Canyon Regional Water Authority, also a member of the regional authority, will contribute to the effort.
Substantial completion of the Carrizo Expansion is scheduled for January 2029. The project aims to address growing water demand across the region by tapping into the deeper aquifer system.
