Wastewater collected by the City sewer system flows to the Wastewater Treatment Plants, where it undergoes a multi-faceted biological process to separate out the solids and treat the water for reuse and recharge. The treated water, called effluent, is sold for use in watering golf courses and construction to reduce potable water demand. The settled solids are dewatered and then hauled off to a landfill for cover. The City has two Wastewater Treatment Plants, the Sundog Wastewater Treatment Plant and Airport Water Reclamation Facility.
Sundog Wastewater Treatment Plant
The Sundog Wastewater Treatment Plant, owned and operated by the City of Prescott is located at 1500 Sundog Ranch Road in Prescott, Arizona. The facility is capable of treating up to 6.0 million gallons/day (MGD) of domestic sanitary sewage and hauled wastewater from commercial haulers.
The Sundog WWTP was constructed in 1979 as an extended aeration oxidation ditch facility. The process expanded in 1989 adding final clarifiers, sand filters and anaerobic digesters. In 2013, nitrification/denitrification improvements were made to the activated sludge process with the addition of submersible mixers, mixed liquor recycle pumps, additional aeration diffusers, dissolved oxygen probes and SCADA upgrades. The facility produces Class B+ effluent suitable for golf course irrigation and recharge to the underlying aquifer at the Airport Water Reclamation Facility.

Airport Water Reclamation Facility
The Airport Water Reclamation Facility, owned and operated by the City of Prescott is located at 2800 Melville Road in Prescott, Arizona. The facility is capable of treating up to 3.75 million gallons/day (MGD) of domestic sanitary sewage and industrial wastewater from the Airpark Industrial area.
The facility completed a major expansion in 2014 to add capacity for increasing wastewater flows. Class A+ effluent is produced and utilized for golf course irrigation and for recharging the aquifer through one or more of the eight percolation basins located on-site. Effluent is used for irrigation and recharge purposes in percolation basins near the Airport WRF to establish artificial recharge credits in the underlying aquifer.
