The scope of the new Eagle Ridge Pump Station includes the following: Demolition and replacement of the existing Eagle Ridge Pump Station onsite with three equally sized VFD pumps of approximately 20 HP and average flow capacity of 620 gallons per minute (gpm) per pump. Two pumps will be used to meet daily demands under a Navajo Pump Station outage with one standby pump. The pumps will be rotated on a regular basis to optimize maintenance. The new Eagle Ridge Pump Station should have a paved area for a temporary backup generator for emergencies. The pump station will have a cam lock transfer switch to transition to the back-up generator. For maintenance needs, the new building will have a roll-up door and an overhead crane system. To meet security standards, the building will have CMU block walls, and the doors will have wall-mounted card readers and tamper plates. CCTV will be installed so that it can transmit security data to Public Utilities Chollas Operations Center. The new Eagle Ridge Pump Station will have upsized 16-inch PVC suction and discharge lines along Wing Flight Ct. The new suction line will connect to the San Carlos Reservoir interconnect transmission line (project currently in design) at the intersection of Wing Flight Ct and Tommy St. The new discharge line will connect to the 16-inch 930 transmission line on Tommy St. Once the new lines to the pump station are in place, the existing 10-inch AC suction line and remaining 24-inch RCSC transmission line will be abandoned. Also, as a part of the scope, the Wingspan & Eagle Ridge Water Regulating Station will have its check valve replaced. Other Details 2.2 Project Description Summary of the Project’s Scope: Eagle Ridge Pump Station scope of work: • Demolish the existing Eagle Ridge Pump Station and piping. • Construction of a new Eagle Ridge Pump Station to accommodate the new 930 zone and provide backup if Navajo Pump Station is down. • Install 3 Variable Frequency Drives (VFDs) pumps. • New Motor Control Center (MCC), which will house the SCADA and Electrical Cabinets. • New pavement area for the temporary backup generator for emergency use only. • Install cam lock transfer switch to transition to the backup generator. • Install a pressure relief valve with the low flow bypass. • Install a new overhead crane system and access hatches. Vertical clearance between the overhead hoist system and valves, pipes, etc., is required for lifting and moving equipment to the station access hatches. • Replace approximately 242 LF of the 10-inch AC discharge line with the new 16-inch discharge line and connect to the new 16-inch (930) transmission line. • Install approximately 240 LF of the new 16-inch suction line and connect to the new 24-inch (849) reservoir transmission line to the new pump station. • Replace approximately 54 LF of 8-inch AC water main. • Abandon approximately 226 LF of existing 24-inch reinforced concrete steel cylinder (RCSC) transmission line.
