Greenfield Water Reclamation Plant

greenfield plant 

The City of Mesa and the Towns of Gilbert and Queen Creek jointly own the Greenfield Water Reclamation Plant. The plant, located on Greenfield Road north of Queen Creek Road in Gilbert, has a present capacity of 16 million gallons per day. The City of Mesa operates and maintains the plant for the three municipalities. The ultimate size of the liquid portion of the plant is 52 million gallons per day. Mesa's ultimate ownership is planned to be 24 million gallons per day.

The plant features on-site treatment of biosolids. The large egg-shaped digesters are part of a state-of-the-art solids handling facility. The current facility can handle 24 million gallons per day of solids. The solids facility will eventually be able to handle 64 million gallons per day. Mesa's portion is 36 million gallons per day. Biosolids from the Southeast Water Reclamation Plant are also treated at this facility, so the need for Mesa's solids capacity is greater than its liquid capacity.

The plant produces reclaimed water with an A+ quality, as defined by the Arizona State Department of Environmental Quality. Mesa's portion of the reclaimed water will be sent to the Gila River Indian Community as part of a water exchange agreement. Gilbert's portion of the water is sent to a nearby recharge facility and/or used in the existing reclaimed water distribution facility.
