City of Redondo Beach Rindge Sewer Pump Station Upgrade

Redondo Beach, CA


The City of Redondo Beach required an upgrade to a large sewer lift station project containing outdated project components and structures, excessive generator noise, and drainage problems. An innovative design solution was developed including using the existing underground concrete vault structure as a foundation for a new aesthetic building, and a second building containing all electrical and generator equipment for enhanced security, improved life of the equipment in a controlled room, and reduction of noise.  The two buildings were creatively integrated into a common structure with an entrance trellis with green plantings.  The front of the buildings contains wire mesh faces with additional low water use landscaping to create a modern mid-century facility feel to blend with the surrounding community.  The front of the facility has permeable areas to reduce and soften the quantity of hardscape and reduce runoff.  The structures and facilities were also raised to remove them from flood hazard areas. The pump station features two-pump duplex (1+1) that has a firm pumping capacity of 1520 gpm and conveys sewage approximately 2,000 feet through a 12-inch force main to the downstream gravity system.


New electrical buildings and enclosures were designed, complete with all architectural, structural, mechanical, HVAC, plumbing, and electrical elements. Construction was sequenced to avoid disruption of sewer pumping operation of the existing pump station so that a transition could be made to the new pump station and including the installation of a temporary generator and temporary 120/208V transformer and panel. The new facility features new electrical service, SES, ATS, MTS, MCC and emergency generator for improvements; and new PLC and SCADA systems.


Key Features:

  • Higher efficiency pumping
  • Installation of permeable pavement
  • Increase of emergency sewage storage
  • Elimination of potential stormwater inflow into the station
  • Structural rehabilitation
  • Corrosion protection coating due to coastal environment
  • Underground concrete vault
  • Aesthetic considerations due to location within a school yard
  • Emergency generator
  • Construction was sequenced to avoid disruption of sewer pumping operation
