Greenfield Water Reclamation
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.
