City of Phenix Zone 3D/4A Water System Improvements Phoenix, Arizona, United States The project involved the design for a new booster pump station (4A- B9) and pressure reducing valve (PRV) station (3D-R12) as part of the Zone 3D/4A Improvement Program. This program is an integral part of the City’s drought contingency planning strategy, providing added flexibility to the City under a variety of possible water supply scenarios. Booster station 4A-B9 will have 40MGD firm capacity initially, expandable to 60MGD, and is designed for bi-directional operation within Pressure Zone 4A. The vertical turbine pumps will be controlled with variable frequency drive to offer maximum operational flexibility. PRV 3D-R12 is designed to transfer up to 60MG from Pressure Zone 4A to Zone 3D. The station includes four 16-inch diaphragm-style PRV’s with accessory equipment and a magnetic flow meter to monitor flow transferred between the zones.

Special considerations associated with this project include tie-ins to two 60-inch prestressed concrete cylinder pipe in Deer Valley Road, easements, and environmental clearance coordination for construction of multiple pipelines within lands owned by the Arizona State Land Department.
