Urban Water Use Objectives – Compiled Report Data

The Making Conservation a California Way of Life regulation requires urban retail water suppliers 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 the information submitted to the State Water Resources Control Board and the Department of Water Resources on the required reporting form. The values have been aggregated into individual tables that roughly correspond to the sections within the reporting form.
