New San Lorenzo Sewage Lift Station will reduce sewage spills

Posted on January 20, 2024


On Thursday, January 18, 2024, a ribbon cutting ceremony was held for the completion of the San Lorenzo Sewage Lift Station project. It is the first state-of-the-art sewage lift station in the City of Santa Ana.

The new station will improve sewage flow and help reduce sewage backups and spills. The project relocated the sewage lift station from Bristol Street, which will help improve traffic flow by no longer requiring lane closures on Bristol when the station needs maintenance.  The new, modern sewage station also provides a safer and more accessible working area for City crews.

Mayor Valerie Amezcua, Councilmember Phil Bacerra and Councilmember David Penaloza joined Interim City Manager Tom Hatch, Public Works Agency Executive Director Nabil Saba, and other City staff and community members in celebrating the opening. After the ribbon cutting, Director Saba gave a tour of the the sewage lift station.

A few fun facts about this sewage lift station:

  • It serves a tributary area of about 380 acres of Santa Ana.
  • The wet pit (where the sewage collects and gets pumped out) is 30 feet long by 6 feet wide by 24 feet deep. That is roughly 32,000 gallons of storage capacity.
  • 13,00 linear feet of new sewer mains
  • 560 feet of 15-inch gravity sewer main
  • 190 feet of 12-inch gravity sewer main
  • 545 feet of 10-inch sewer force main
  • 3 sewer grinders
  • 3 pumps (1 lead, 1 lag, 1 standby)
  • 1 bubbler system for odor control
  • Each pump can produce approximately 1,180 gallons per minute or 1.7 million gallons per day during dry weather flows.
  • All sewage from the station is pumped to a manhole connecting to the Orange County Sanitation District Line at the intersection of Bristol and Segerstrom Avenue.

We thank the City’s leadership, the Mayor and City Council for their support of this project.  We also thank our City staff for leading the efforts in guiding the construction for this project: City Engineer, Rudy Rosas, Water Resources Manager Cesar Barrera, Water Principle Engineer Armando Fernandez, Construction Principle Engineer Sean Thomas, Construction Engineers Alex Olmos and Ed Torres, Inspector Sal Salcido, and Water Systems Operator Jorge Navarro.
