Laundry to Landscape Ordinance Converts Wastewater into Sustainable Assets
WaterNow Alliance and Western Resource Advocates (WRA) partnered with the City of Golden to develop Colorado’s first graywater laundry-to-landscape aimed at reducing water usage by allowing laundry water to irrigate non-edible plants on single-family residential properties.
In September 2020, the City of Golden approved Ordinance 2143, becoming the first ordinance in Colorado to allow water from laundry machines and laundry room sinks to water non-edible outdoor plants, transforming wastewater into a valuable commodity. At a 5% adoption rate among single-family homeowners, the Ordinance 2143 would save approximately 514,000 gallons (1.6 acre-feet) annually.
