New Water Resources

New Water Sources

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 has already made great strides in diversifying our water supply and is working to secure San Antonio's water future.

DRAFT 2017 Water Management Plan

In a continuing effort to gather community feedback, SAWS wants to hear from you on its draft of the 2017 Water Management Plan.

2012 Water Management Plan

The updated plan addresses the city's future needs by calling for investment in new supplies and a continued commitment to water conservation.

Current Water Supply Projects

SAWS is moving forward with water supply projects that provide ratepayers with the most viable and affordable options to secure current and future water supplies.
