RECOMMENDATIONS:
That the City Council:
Approve a Professional Consultant Services Agreement with Michael K. Nunley & Associates, Inc. dba MNK, of Irvine, California to complete Civil Design Engineering Services for Western Avenue and Garden Hills Way Wastewater Lift Stations in the amount of $273,134.
Authorize the City Manager, or his designee, to execute the Professional Consultant Services Agreement with Michael K. Nunley & Associates, Inc. dba MKN, of Irvine, California including making minor and non-substantive changes.
BACKGROUND:
The Western Avenue Wastewater Lift Station is located at 7700 Western Avenue in the City of Riverside. The lift station was constructed in 1987 and is a duplex submersible pump station with two (2) five horsepower (HP) pumps rated at one hundred-sixty gallons per minute. Mechanically, the pump motors and their components are at the end of their useful life. Similarly, the electrical and control mechanisms of the station are outdated, unreliable, and in constant need of repair. Over the years, the concrete slab foundation for the station has deteriorated and is structurally unstable. Further, the retaining wall on the east side of the station exhibits cracks and needs to be examined for repairs. This station will need to be replaced by a new structure in conformance with City of Riverside Sewage Lift Stations and Force Main Guidelines.
The Garden Hills Way Wastewater Lift Station is located at 6364 Garden Hills Way in the City of Riverside. The lift station was constructed in 2002 and is a duplex self-priming pump station with two (2) fifteen HP self-priming pumps rated at one hundred twenty-five gallons per minute. The station was built by the developer for the residential Tract 28728-2 as a temporary station, which is supposed to be removed when the downstream residential Tract is developed. Unfortunately, the downstream housing project has not materialized, and the Garden Hills Way Wastewater Lift Station needs repairs. The lift station was built above the wet well, which is an enclosure to store incoming sewage flow. This configuration does not afford the City maintenance crew appropriate clearance to perform routine maintenance. The lift station also does not meet the City’s specification for a small duplex station.
Both the Western Avenue and the Garden Hills Way wastewater lift stations will need to be replaced with new sewer lift stations that conform to the City of Riverside Sewage Lift Stations and Force Main Guidelines.
DISCUSSION:
On March 12, 2024, the City’s Purchasing Division released Request for Proposal No. 2351 for Civil Design Engineering Services for Western Avenue and Garden Hills Way Wastewater Lift Stations through the City’s PlanetBids bidding platform.
