Water:
Precipitation Harvesting Pilot Projects

Our Position: support
Bill Number: HB 1129
Sponsor: Rep. Looper/ Sen. Romer
Legislative Session: 2009

Directs the Colorado water conservation board (board) to select the sponsors of up to 10 new residential or mixed-use developments that will conduct individual pilot projects to collect precipitation from rooftops and impermeable surfaces for nonpotable uses. Specifies that the purpose of the pilot projects is to: 

  • Evaluate the technical ability to reasonably quantify the site-specific amount of precipitation that, under native conditions, accrues to the natural stream system via surface and ground water return flows;
  • Create a baseline set of data and sound, transferable methodologies for quantifying native plant consumption and measuring return flow patterns;
  • Evaluate a variety of precipitation harvesting system designs;
  • Measure precipitation capture efficiencies;
  • Quantify the amount of precipitation that must be augmented to prevent injury to decreed water rights;
  • Compile and analyze the data collected; and
  • Provide data to allow sponsors to adjudicate permanent augmentation plans.

Directs the board to establish criteria and guidelines for applications and the selection of pilot projects, including selection of pilot projects to represent different geographic and hydrologic areas in the state and giving priority to pilot projects that are located in areas that face renewable water supply challenges and that promote water conservation.

Requires pilot projects to: 

  • During the term of the pilot project, operate according to a substitute water supply plan if approved annually by the state engineer in which the net depletion is calculated as a minimum of 30% of the total captured and measured precipitation;
  • Upon completion of the pilot project, apply for a permanent augmentation plan or retire the pilot project;
  • Submit an annual preliminary report to the board and the state engineer summarizing the data collected; and
  • Submit a final report to the board and the state engineer by January 15, 2019.
Requires the board and the state engineer to brief the water resources review committee on the pilot projects by July 1, 2014, and to provide a final briefing to the water resources review committee by July 1, 2019. Repeals the act, effective July 1, 2020.
