SAWS Updates 50-year Water Management Plan

Download 2017 Water Management PlanThe SAWS Board of Trustees in October unanimously approved the 2017 Water Management Plan, a guiding document that outlines how the utility will meet San Antonio’s water needs over the next 50 years.

This updated document comes as SAWS — now one of the largest municipal water utilities in the country — celebrates its 25th anniversary. Nationally recognized for sustainable and responsible management, SAWS oversees existing water supplies while developing new water sources for the future — helping diversify its water supply and ensuring sustainable, affordable water services for generations to come.

The SAWS Board adopted the updated plan after a months-long public review that included input from the community, environmental organizations and City Council members. Based on the feedback received, changes were made to the document, providing more details on specific water management strategies, as well as more supporting background information.
