Reporting of Water Use and Water Conservation Data (HB10-1051) 

In 2010, the Colorado General Assembly adopted HB10-1051 which requires covered entities (retail water providers who sell 2,000 acre feet or more of water annually) to report, on an annual basis, water use and conservation data to be used for statewide water supply planning. The bill directed the CWCB to adopt guidelines regarding the reporting of water use and conservation data by covered entities (Guidelines), and to report to the legislature regarding the Guidelines.

HB10-1051 directed the CWCB to develop reporting Guidelines through a public participation process that included outreach to stakeholders from water providers with geographic and demographic diversity, nongovernmental organizations, and water conservation professionals.

The reporting Guidelines include clear descriptions of customer categories, uses, and measurements; how the Guidelines will be implemented; and how data will be reported to the Board.

Statewide water supply planning efforts, such as the Statewide Water Supply Initiative (SWSI), which utilizes future statewide water demand projections with-and-without various levels of municipal and industrial water conservation, rely on statewide water use and water conservation data.

Data reported under HB10-1051 will further support statewide water supply planning efforts by improving the quantity and quality of data available and improving consistency in the data reporting.

Guidelines and Definitions
Online Reporting Tool

To facilitate the data reporting process, the CWCB has created an online reporting for water conservation and water use data. By June 30 of every year, all covered entities will report the previous calendar year data using the online reporting tool.

  • February 1, 2019: CWCB reports to legislature on the Guidelines and data collected under the Guidelines.  

For Public Users:
In line with Colorado’s Transparency Online Project and the next revision of the Statewide Water Supply Initiative (SWSI), the Colorado Water Conservation Board is opening the HB10-1051 data for research purposes to foster innovation.  Colorado’s water future is uncertain and a broader dissemination of water use and water conservation data will support more research arenas in defining and implementing solutions to the statewide water supply-demand gap.

The purpose of the HB10-1051 data reporting, per Section 37-60-126(4.5)(a), C.R.S., is to provide water use and conservation data for statewide water supply planning. The data collection process is designed to provide better, more frequent, and more reliable data than currently available through standardized reporting requirements by each covered entity as defined in the HB10-1051 Guidelines. However, this does not necessarily standardize the data collection process and does not require entities to change their data/billing systems to report in a particular format.

While the Colorado Water Conservation Board makes every attempt to verify the submitted data, data handling errors occur. The Colorado Water Conservation Board does not manipulate the submitted data but simply makes this data available “as-is”. The Colorado Water Conservation Board and/or Colorado Department of Natural Resources shall not be held liable for improper or incorrect use of the data described or information contained on these pages. These data, information, and related tables are not legal documents and are not intended to be used as such. The user should exercise caution in using the data without a proper QA/QC process and without understanding the context from which the submitted data originates. The Water Efficiency Data Portal supports the annual reporting process and allows covered entities to describe data collection and preparation metadata, as well as any cases where certain definitions in these Guidelines are not directly applicable. The statewide and basin wide planning efforts are not intended to replace water conservation, water resource planning, nor projections prepared by local entities for project-specific purposes. This data alone it is not intended to be used to provide comparisons between utilities.
