CITY OF PHOENIX LOWER BUCKEYE SEWER EMERGENCY REPAIR, REHABILITATION, AND REPLACEMENT
Abstract:The Lower Buckeye Sewer Rehabilitation/Replacement Project was the most complicated large diameter sewer rehabilitation project ever conducted by the City of Phoenix. From the initial identification of the need for repair through the final construction activities, this section of pipeline provided a variety of challenges. This high profile project included:
Sewer investigation to proactively identify condition and repair needs
Pipeline collapse and emergency repair of a 54-inch diameter sewer
Installation of 790 feet of an 84-inch diameter sewer with multiple large utility conflicts
Bypass pumping of 150 million gallons per day (mgd) to allow rehabilitation of 1,100 feet of 72-inch diameter sewer.
This project clearly identified the priority and risk associated with corrosion of unlined concrete sewers within the Phoenix metropolitan area. The exponential rate of corrosion that occurred within the pipeline mandated immediate attention to maintain service and prevent sanitary sewer overflow.
