The project requires coordination of LEE + RO’s design with the designs of the Matthews Transmission Pipeline, the Menifee Road Transmission Pipeline, and the Romoland Feeder Replacement designs, which others are preparing.

Center Street Lift Station to Replace Cadena Creek Lift Station

The Pierce Street Pump Station is the largest wastewater lift station in the City of Riverside. It handles on average 4.5 MGD and is currently experiencing operational challenges. Issues include non-operational valves, leakage from the wet well into the dry well, aging mechanical equipment, and outdated electrical components.

The San Bernardino Municipal Water Department (SBMWD) owns and operates the Meridian Lift Station, which is adjacent to many single-family residences, as well as the San Bernardino Flood Control District’s Randall Basin, near Randall Avenue and Meridian Avenue in the southwest portion of the City of San Bernardino. The lift station was constructed and placed into service in 1983. At 38 years old, it is in relatively poor condition and suffers from operational challenges.

The City of Riverside’s Public Works Department is experiencing operational challenges at their Wood Road sewer pump station. Some of the issues are heavy ragging, extended VFD ramp-up time, pumps not operating at recommended efficiencies, and most recently, failure of the ultrasonic sensors.

The city of Riverside has contracted LEE + RO to prepare the construction documents for the replacement of two existing wastewater lift stations: Fairgrounds Street Lift Station and Dexter Drive Lift Station. Both of the existing lift stations were originally constructed in the late 1960s with a wet well manhole and a pump chamber vault with pedestal mounted pumps in a duplex (duty/standby) configuration.

LEE + RO has been awarded a contract from the Los Angeles County Department of Public Works (LACPW) for design improvements at a sewage lift station and force main in the City of San Dimas.
