NWRI completes guidelines for DPR in Colorado

NWRI recently delivered guidelines for safe and effective implementation of direct potable reuse in Colorado. The state introduced a comprehensive Water Plan in 2015, with the goal of identifying water supply and demand strategies, which include conservation, storage, land-use planning, sharing water with agriculture, and reuse. The plan set forth measurable objectives, goals, and actions by which Colorado will address its projected water needs and measure progress.


We engaged a six-member panel of experts who, over the course of three meetings in two years, developed this consensus-based technical report. WateReuse Colorado sponsored this effort to provide expert guidance to the Colorado Water Conservation Board and the Colorado Department of Public Health and Environment.
