2026 Regional Water Plan Board-Adopted Population and Municipal Demand Projections
The data on this website supports the 6th regional water planning cycle. Population projections utilize the Texas Demographic Center's 2022 county-level population projections and Regional Water Planning Groups (RWPGs) have reviewed and provided input on the utility and county-level population projections. Municipal water demand projections are a function of the population projections, baseline Gallons per Capita per Day (GPCD), and projected plumbing code savings. These projections were adopted by the Board on November 9, 2023. Historical data was developed using the TWDB's Water Use Survey and the U.S. Census Bureau county-level population estimates and counts.
