The City of Flagstaff has been using reclaimed water for irrigation since 1965. The City's reclaimed water system was expanded in the mid-1990's when the Rio de Flag Water Reclamation Plant was constructed as a scalping plant, treating liquids only and sending solids to the Wildcat Hill Water Reclamation Plant. Effluent from both Water Reclamation Plants is currently distributed for use.
As a part of the reclaimed water system, the "purple pipe" distribution network was designed to provide reclaimed water to larger-volume outdoor water users as a way to conserve potable water supplies for human consumption and household uses. The map, below, displays the current reclaimed water pipe networks.
Today, reclaimed water makes up 20% of the city's total deliveries. In the future, expansion of the existing reclaimed water infrastructure could offset even more of our potable water usage and allow for a variety of new reclaimed water users, including businesses and households.
