Treatment Facilities
In the mid 1980's the City of Scottsdale built it's first wastewater treatment facility, the Gainey Ranch Reclamation Plant. It was constructed for the sole purpose of providing all of its’ effluent for irrigation of the Gainey Ranch Golf Course and later to Rotary Park; which is still its mission to this day. At the time of construction the concept of water reuse was rare and this plant represented leading edge technology. Over next few years the City of Scottsdale expanded its operations. Today the City operates three water treatment facilities, the Central Arizona Project Water Treatment Plant (CAP), the Central Groundwater Treatment Plant (CGTF) and the newest facility the Chaparral Water Treatment Plant. The City also operates two water reclamation facilities, at Gainey Ranch and the Water Campus.
The three water treatment facilities can produce a combined total of over 115 million gallons per day (MGD) of drinking water. The CAP water plant is a conventional water plant located on Union Hills east of Pima. The source water is the CAP canal located just north of Frank Lloyd Wright Blvd. The CGTF is a groundwater treatment plant and is supplied though five wells. Chaparral, the newest facility, uses membranes in its process. Its source water is the Arizona Canal which is located just north of McDonald and Hayden
The Water Campus was constructed in the late 1990’s. Its mission, as with Gainey Ranch, is to provide final effluent to selected group of golf courses for turf irrigation. The City of Scottsdale, being true to its past of being on the leading edge of technology, constructed the Water Campus with the newest technology available. A new advanced water treatment facility was built and further treats the effluent to drinking water standards with the aid of micro filtering and reverse osmosis. This highly treated water is then recharged through various wells. This groundwater recharge enables the City to meet peak demands for potable water from other water wells by ‘banking’ excess water. Today the total amount of wastewater that can be processed by these facilities is approximately 23 MGD.
