The objective of this project was to turn an existing 1.5 mgd secondary treatment process/plant on 1.2 acres of
useable land into a 3 mgd tertiary treatment process that can produce reuse water to the highest
reuse standards in the State of Arizona.
The Randolph Park Water Reclamation Facility (WRF) in Tucson, Arizona has
been in operation as a 1.5 mgd secondary treatment facility since 1975. The facility has had a
shutdown period since 1995 when a golf course expansion terminated flow to the facility. With
the implementation of an Inter-Governmental Agreement, as well as regulatory changes in
water quality requirements, this facility needed to be reactivated, expanded and upgraded to a 3
mgd tertiary treatment WRF, with the highest possible water quality standards for reuse (Class
A+) in the State of Arizona. Since start of operation of this facility, the plant has met and significantly exceeded these
permitting requirements. The
benefits and significance of this project include:
highest quality of reuse water in the State of Arizona made available for wetlands use
and subsequent recharge to a severely depleted aquifer;
highest quality of reuse water in the State of Arizona made available for reuse in the
City of Tucson's reuse system and as irrigation for an adjacent golf course; and,
doubled reuse production at an existing facility and reduced wastewater flow to a
downstream facility.
This is a truly unique application of new technology within existing facility constraints to
obtain the highest quality (Class A+) of reuse water in the State of Arizona. Given our
dependence on this dwindling resource we can only expect regulatory requirements for
wastewater treatment effluent to increase, resulting in direct reuse becoming an acceptable
practice, as well as necessary.
