Lift Station 6 Force Main Replacement

Construction Update

Project Overview

Lift Station No. 6 (LS 6) force main was constructed by South Coast Water District (District) in the mid-1980s to convey sanitary sewage from the City of Dana Point to the Coastal Treatment Plant in Laguna Beach. LS6 is located on Ritz Cove Drive and is connected by a 2,400-foot force main to a manhole on Monarch Bay Drive. The District will be replacing and relocating the force main to Pacific Coast Highway, connecting to a new gravity sewer main in Monarch Bay Drive.  The replacement force main and new gravity sewer main will be constructed with a more reliable pipe material that is not susceptible to damage or corrosion by hydrogen sulfide gas or corrosive soil.

Project Need

Since it was built in the mid-1980s, the existing force main has deteriorated at several locations because of hydrogen sulfide gas, which naturally forms in sewage. LS6, including the force main, is a critical facility due to the volume of flow it conveys and its location within a residential area near the ocean.  The replacement force main and new gravity sewer main will improve reliability and integrity, avoid impacts to the environment due to potential spills, and extend the service life of the pipe. 

Construction Hours

Construction will be limited to Monday through Friday between 8:30 a.m. and 3:30 p.m. on Pacific Coast Highway and Monday through Friday between 7:30 a.m. and 5 p.m. on Monarch Bay Drive (Note: The transitions to and from the tie-ins must occur during low flow, between 12 a.m. and 5 a.m.)  

Project Cost

The cost of the project is estimated to be $1.9 million dollars. 

Project Timeline

Construction will begin in June and is estimated to be complete in October 2019.
