Colorado Springs resident Bradley White says a simple lever in his laundry room sends water from his washing machine outside and helps water shrubs in his yard. White has installed these residential graywater systems professionally in California for years. But in Colorado Springs, where he lives, city code prohibits graywater use and only allows residents to use water once. … State-compliant graywater systems can be expensive, and few Colorado communities have widely adopted programs, the Colorado Springs Utilities wrote in an emailed statement explaining its stance on graywater. The city also wants more time to study how home systems would fit into its broader water reuse strategy. Right now, the utility captures and reuses water through a centralized treatment system.
