2026 Regional Water Plan DRAFT Municipal Demand Projections

The data on this website supports the 6th regional water planning cycle and was released in February 2023. Draft Water User Group (WUG) population projections are based on the Texas Demographic Center's 2022 county-level population projections. Municipal water demand projections are a function of the draft population projections, draft baseline Gallons per Capita per Day (GPCD), and projected plumbing code savings. All data is subject to change per Regional Water Planning Groups' review. Historical WUG data was developed using the TWDB's Water Use Survey and the U.S. Census Bureau county-level population estimates and counts. Download data and methodology documents below each dashboard.
