Over the past 50 years, the Utah Division of Water Resources (DWRe) has employed various procedures to obtain needed municipal and industrial (M&I) water data. In recent years, these procedures have become more comprehensive. When DWRe began water planning in the 1960s, available data consisted mainly of supplies and uses for the entire state. At that time, Utah's agriculture uses far exceeded M&I uses. M&I water use was generated by multiplying estimated per capita rates by census population data.


By the early 1980s, M&I diversions made up a larger percentage of total statewide water uses; and with unprecedented population growth, the entire water community began an increased focus on M&I water supplies and uses. The Utah Division of Water Rights, in cooperation with the U. S. Geological Survey launched a program to collect yearly statewide M&I data. The procedure involved mailing a survey designed to query each major public water supplier about its sources of water supply and uses. This program continues today and is now a cooperative effort, administered by the U. S. Geological Survey and the Divisions of Water Resources, Drinking Water and Water Rights. In addition, the U. S. Geological Survey summarizes national M&I water use data every five years in the report, Estimating Use of Water in the United States. The DWRe relied on both data sources in its planning efforts throughout the 1980s.


With the completion of the Municipal and Industrial Water Supply Studies for all of the hydrologic basins of the state, the DWRe now offers a statewide M&I summary report to enhance the capabilities of water managers of the state to quickly and accurately access information about Utah's M&I water use. This program continues to update M&I water data for each hydrologic area of the state every five years.
