Award Construction and Construction Engineering Contracts for the San Lorenzo Sewer Lift Station Project October 1, 2019 Page 2 inspection and testing, and an authorized contingency of $1,140,975, to be paid with Sewer Connection Projects funding. DISCUSSION The City of Santa Ana Segerstrom Sewer Lift Station, located on the east side of Bristol Street, about 300 feet north of Segerstrom Avenue, has been in service since 1965. This City -owned facility is providing a service to a tributary area of approximately 380 acres and pumping approximately 1.2 million gallons of sewage every day. Currently, this 55-year-old station has surcharge problems with upstream sewer mains and requires frequent maintenance and repair. In addition, City maintenance crews and vehicles must divert traffic out of the northbound traffic lanes on Bristol Street to access the facility. Maintenance efficiencies can be improved by relocating the facility and replacing the failing pumps and equipment. The proposed new San Lorenzo Sewer Lift Station will be located at the southwest corner of the intersection of San Lorenzo Avenue and Baker Street (Exhibit 1). The scope of work includes approximately 880 linear feet of 15-inch and 12-inch gravity sewer mains and 600 linear feet of parallel 10-inch force mains, sewer manholes, sewer gate valves, 3 vertical dry pit sewage pumps, motors with variable frequency drives, in -line grinders, flow meter, underground concrete dry well and wet well, piping, fittings, and appurtenances. Moreover, this project will construct a new concrete masonry unit block building with a Heating, Cooling & Ventilation (HVAC) system, ducting, rails, hoist system, gravity scrubber system, electrical and instrumentation; plus site grading, landscaping, and irrigation improvements. Once completed, the improvements will improve system efficiency, reliability, and enhance safety.
