Modernization of Busch Garden and Rosemont Sewer Pump Stations (76917)

The City is undertaking critical infrastructure improvements at the Busch Garden and Rosemont sewer pump stations to ensure continued reliability, operational efficiency, and regulatory compliance. These facilities play a vital role in the City’s wastewater management system, and their modernization is essential to support current and future service demands.

This project involves the demolition of outdated mechanical and electrical systems, including the complete removal of the existing Busch Garden pump station building. New installations will include upgrades to the existing sewer pumps, a precast concrete wet well, updated electrical panels, SCADA communication systems, and a structural pad for a new chemical storage and feed system. A temporary sewer bypass system will be implemented to maintain uninterrupted service during construction.

The proposed upgrades will significantly enhance the performance and resilience of the pump stations, reduce maintenance needs, and improve system monitoring and control.

The City of Pasadena manages three sewer pump stations that pump waste up to a higher elevation for deposit into the City's gravity sewer system. As part of the FY 2019 Sewer Master Plan process, all three pump stations were inspected according to current standards. Rockwood Pump Station was constructed in 2016, but Rosemont and Busch Garden pump stations are each over 70 years old and require upgrades to station housing, generators, ventilation systems, SCADA communications, and site access. These upgrades will decrease the possibility of sanitary sewer overflows, shorten response time with updated communications features, increase worker safety, and ensure uninterrupted wastewater flow.
