Special Report: Just 53% of Colorado cities use permanent watering restrictions, despite proven savings
Despite a stubborn, 20-year drought and reservoirs whose supplies are below normal, Colorado communities remain split on whether to impose permanent outdoor watering restrictions, according to a Fresh Water News analysis of local watering rules.
According to the analysis, which examined rules in 15 cities representing the state’s different geographies and major population centers, eight of the cities surveyed have enacted permanent restrictions. Seven cities have not, opting instead to enact variable, temporary watering rules each year.
But when communities do impose permanent rules, rather than adjusting them each spring depending on snowpack and reservoir levels, significant savings occur, with some communities seeing reductions of more than 40 percent in peak summer water demand, according to a recent study by Alliance for Water Efficiency, a nonprofit representing water and wastewater utilities across North America.
