Water use and supply data for 2015 joined to spatial boundaries. GPCD = Gallons Per Capita Day or Gallons Per Person Per Day. Supply and Use numbers are in Acre Feet Per Year (ACFT).This database contains municipal, institutional, commercial and industrial water use data gathered by the Utah Division of Water Rights for the 2015 calendar year. The Utah Division of Water Resources has analyzed water use data every five years since 1990; however, this new 2015 dataset marks a significant methodologic and data accuracy milestone.The updated and improved methodology is based on recommendations from a 2015 Legislative Audit, 2017 Legislative Audit Update and a 2018 third party analysis of our processes. All recommendations necessary for this data release have been implemented. Changes in recommended secondary water use estimate inputs, as well as the transfer of second homes from the commercial category to the residential category, are examples of updates that impact categorical or total use estimates.While we are encouraged by the improvements, these changes make comparing the 2015 numbers to past water use data problematic due to the significant methodology differences. As a result, we will be using the 2015 data as the new baseline for comparison and planning moving forward. The audit reports and third party recommendations can be found at: https://dwre-utahdnr.opendata.arcgis.com/pages/municipal-and-industrial.Likewise, comparisons from region to region within Utah are problematic due to differences in climate, number of vacation homes and other factors. Comparisons between Utah’s water use numbers and data from other states have little value given there is no nationally consistent methodology standard for analyzing and reporting water use numbers.It should be noted that administrative processes were changed in 2016 to ensure community water system data corrections are updated in the Utah Division of Water Rights’ database and website; however, these updated processes did not occur for the 2015 data. As a result, the data released in this database will often differ from what is reflected on the Utah Division of Water Rights’ website. That said, this data underwent both legislative auditor and third party review, and our division is confident that it is reflective of regional water use and useful for planning purposes.Utah’s Open Water Data Portal can be found at https://dwre-utahdnr.opendata.arcgis.com/. The division believes that data accessibility and transparency is vital as water decisions become more complicated and critical.
