Fort Collins City Council Considering Graywater Use 

To move toward one of the Fort Collins City Council priorities, City staff drafted graywater ordinance language and is planning for its potential use in the community. The ordinance aligns with State of Colorado requirements while considering water rights and ensuring public health is protected.

The City is looking at graywater as another water efficiency tool. The ordinance would allow homeowners and businesses to capture water from clothes washers, showers, bathroom and laundry sinks, and divert it to toilet flushing before the water travels to the City’s wastewater system. If approved, this ordinance would provide the right water for the right use since toilet water doesn’t need to be treated to drinking standards.

Fort Collins City Council is scheduled to hear the first reading of the ordinance on August 16, 2022.
