Current Water Supply Projects

Current Water Supply Projects

Affordable. Sustainable. Diversified.

Just a few years ago, San Antonio was totally dependent on day-to-day pumping from the Edwards Aquifer for the city's water needs. Now, as a result of extensive planning and funding through the Water Supply Fee, SAWS is working to secure San Antonio's water future.

SAWS has one of the most diversified and innovative water supply portfolios in the country. Over the last 20 years, SAWS has led the country in developing water supply, for the purposes of reducing its reliance on the Edwards Aquifer and diversifying its portfolio, planning for one of the highest population growth corridors in the nation, and preparing for drought. San Antonio leadership has worked over these last 20 years to radically change the water supply situation, thereby sustaining a thriving economy.
