Urban Water Use Objectives – Relevant Data

Published by California State Water Resources Control Board | State of California | Metadata Last Checked: February 26, 2026 | Last Modified: 2026-01-29T17:59:08.132600
The Making Conservation a California Way of Life regulation requires urban retail water suppliers (URWS) to annually calculate their Urban Water Use Objective (UWUO), which is the sum of efficiency budgets for a subset of urban water uses: residential indoor water use, residential outdoor water use, real water loss and commercial, industrial and institutional landscapes with dedicated irrigation meters. Each efficiency budget will be calculated using a statewide efficiency standard and local service area characteristics such as population, climate, and landscape area. Where relevant, suppliers may also include in their objective “variances” for unique uses, or a bonus incentive for potable recycled water use. This dataset contains information gathered from reports submitted to the State Water Board, the Department of Water Resources, and other relevant information sources. It also contains information derived by the Board and the Department for the purpose of the regulation. The values in these tables are used to pre-fill a number of fields within the UWUO reporting form that URWS are required to submit by January 1 of each year, starting in 2025. To view the submitted values, please visit [this page](https://data.ca.gov/dataset/urban-water-use-objectives-compiled-report-data).
