Reclaimed water is produced by both of the City’s wastewater treatment plants. Treated effluent from the Wildcat Hill Plant supplies irrigation water to golf courses and recreational areas on the East side of Flagstaff. Treated effluent from the Rio de Flag Water Reclamation Plant supplies most public schools and parks, as well as a golf course, cemeteries, public landscapes, and residences. Reclaimed water is one of the most significant water conservation tools the City has. Over 500 million gallons of reclaimed water are used each year for irrigation, and new customers continue to come on line.
