    After more than 60 years of service, the Roger Road Wastewater Reclamation Facility is no longer treating Pima County’s wastewater.
    On Jan. 8, 2013, the last flows were diverted from the old Roger Road plant to the new Agua Nueva Water Reclamation Facility - a state-of-the-art plant that will allow Pima County to meet new strict environmental standards for effluent discharges into the Santa Cruz River. 

    Although the Roger Road plant kept the community safe from water-borne diseases for decades, most people associate the old facility with odors that have been problematic for westside residents and businesses and travelers along Interstate 10 and nearby surface streets.  

    The Agua Nueva plant has state-of-the-art odor control. Once clean up and closure of the Roger Road facility is completed, residents and visitors to the Westside will no longer be affected by treatment plant odors. Cleanup activities are expected to take approximately six months and may result in some minor odors.

    The startup of the Agua Nueva facility marks the completion of regulatory requirements under the Regional Optimization Master Plan, which is the overall plan to upgrade and rehabilitate aging infrastructure to come into regulatory compliance and meet capacity needs to at least 2030.

    Other major components included the expansion of the existing Ina Road plant, which has been renamed the Tres Rios Water Reclamation Facility, and the construction of a state-of-the-art laboratory and training facility.

    The startup of the Agua Nueva Facility is being realized one year ahead of the regulatory compliance schedule.
