Municipal Conservation

In Water for Texas: 2017 State Water Plan, municipal water conservation strategies for the year 2070 are projected to provide 811,000 acre-feet to help meet the projected needs for additional water supplies. This volume of municipal water conservation represents 9.6 percent of the total volume of recommended strategies to meet water supply needs in 2070. This is an increase of 2.4 percent from the identified municipal water conservation strategies in the 2012 State Water Plan. TWDB staff takes pride in providing services that help Texans establish effective municipal water conservation programs by implementing best management practices.

TWDB staff assists water utilities with development of required municipal water conservation plans and water loss audits; collects data for the required conservation plans and annual reports and for water loss audits; and also provides resources for industrial, commercial, institutional water conservation programs.

Municipal water conservation programs can benefit by using information provided by Best Management Practices, public awareness programs using Water IQ, TWDB's conservation education programs, including TWDB Kids, and the TWDB's conservation literature resources. Information in these resources includes activities for municipal utilities and for individual residences and businesses.
