Conservation Resources for 2026 Regional Water Plan Development

This page contains conservation resources available for regional water planning groups to consider during development of the 2026 Regional Water Plans.

Resource Guide

• Conservation Resource Guide for Development of the 2026 Regional Water Plans Overview of conservation resources provided on this webpage and how they may be used to support development of conservation water use reduction strategies, water loss mitigation strategies, and the conservation subchapter of the 2026 Regional Water Plans.

Conservation Dashboard

• Conservation Information Dashboard for Water Supply Planning - Interactive dashboard visualizing data from the water use survey, water conservation plans, water conservation annual reports, and the 2021 Regional Water Plans. Users can explore historical gallons per capita per day (GPCD) statistics by utility size and region, GPCD trends and targets by public water system and water user group, recently implemented conservation best management practices, and recommended conservation projects from the 2021 Regional Water Plans. Data presented in the dashboard may be downloaded in spreadsheet form.

Water Loss Audit Data

Spreadsheets of utility-reported water loss audit data. May be used to describe water loss audit information for the region in Chapter 1 of the regional water plan and for consideration of water loss mitigation strategies.

• TWDB Water Balance Data Reports
• 2022 Water Loss Audit Data by Region
• 2021 Water Loss Audit Data by Region
• 2020 Water Loss Audit Data by Region
• 2019 Water Loss Audit Data by Region
• 2018 Water Loss Audit Data by Region
• 2017 Water Loss Audit Data by Region
• 2016 Water Loss Audit Data by Region

GPCD Related Data

• 2026 RWP Baseline GPCDs and WUG Adjusted GPCD - This spreadsheet was developed based on recommendations from the Water Conservation Advisory Council and may assist in setting GPCD goals.
• Plumbing Code Savings - This spreadsheet contains plumbing code savings presented in gallons per capita per day for inclusion in the 2026 Regional Water Plans.
• WUG Adjusted Planning GPCD with Water Efficiency and Conservation Savings (SARA Report ID 102) - currently a secure report accessible by RWPG consultants only through the TWDB Secure Agency Reporting Application. This report calculates adjusted water user group planning GPCDs after water efficiency and recommended conservation strategy savings and may assist in setting GPCD goals.
