2017 Water Management Plan

Securing San Antonio's Water Future

Download 2017 Water Management PlanWater is vital to San Antonio’s quality of life. Our county’s population is growing by tens of thousands of new people every year, and the demand for water is growing with it.

To help meet this growing need, San Antonio Water System regularly reviews and updates its Water Management Plan to ensure the community has plentiful water supplies for generations to come.

This is an ongoing process that takes into account a variety of variables, including rain and drought predictions, shifting demographics, and political and environmental changes.

On Oct. 10, 2017, the SAWS Board of Trustees unanimously approved the 2017 Water Management Plan. Based on stakeholder feedback received during the review stage, several changes were made to multiple sections of the document to provide more detail and understanding.

NOTE: Since the October 2017 SAWS Board meeting, three changes were made to the content of the 2017 Water Management Plan in an effort to improve the transparency and accuracy of the document:

  • A study on the water savings of permanent once-per-week watering was added to the end of the appendix.
  • Integration cost ($/AF) of the Vista Ridge project was added to the table on page 94.
  • Pie charts on pages 5 and 83 were corrected.
