Why can Denver Water customers reuse their own graywater for outdoor use?
A. Colorado water law allows each customer just one use of water before it goes down the drain, through a wastewater treatment plant and back into the river for others to use. By law, Denver Water customers are not allowed to use bath or laundry water (commonly referred to as graywater) for other purposes. After this water is used once by Denver Water customers, it must return to the South Platte River where it will be used seven or eight times before it gets to Nebraska. Denver Water does not endorse graywater systems.
