Newport Blvd Sewer Project

Pipe Bursting and more on Newport Blvd. Project

Post Date:02/02/2018


The following are activities planned to occur starting next week: 


Potholing will take place near the northeast corner of Newport Blvd. and Hospital Rd.  While this work is taking place, the right turn lane will be closed.  Access to Old Newport Blvd. can be made using the Newport Blvd. off-ramp.

Potholing is the digging of a test hole to expose underground utilities to determine their horizontal and vertical location.  A vactor truck will be used to assist with this activity.  Please be advised that this work may be loud from the vactor truck. 

Activities are scheduled to take place Monday, February 5, between 7 a.m. and 5 p.m.

Pipe Bursting 

Pipe bursting activities will take place along northbound Newport Blvd. between the Newport Blvd. ramp and Hospital Rd.  Previous pipe bursting activities had taken place in November and December.Pipe Burst Head Tool

Pipe bursting is the replacement of the old pipe by fragmenting the existing pipe with a bursting head tool (see photo on the right) and installing a new pipe in its place.  The new pipe is placed in the same alignment as the existing pipe.  Expect equipment and vibrations close to the work area.  The public may notice increased construction noise, similar to a constant hammering sound. 

Activities are tentatively scheduled to take place Tuesday, February 6.  Pipe bursting will start around 8 a.m. and will continue until completion, possibly extending to nighttime hours.

Cured-in-Place Pipe 

Cured-in-place pipe (CIPP) activities will occur along northbound Newport Blvd. between Hospital Rd. and  Industrial Way.  Expect reduced travel lanes during this work.

CIPP is a trenchless rehabilitation method of lining existing sewer pipelines.  CIPP involves lining the existing pipeline, a process which, once installed, requires continuous operations to properly cure the lining, essentially creating a new pipeline.  This work includes diverting of bypassing sewer flows, interior pipe cleaning, repairs, CIPP installation and curing, pre- and post- closed circuit television (CCTV) video surveillance, and testing.   During the curing process, a temporary resin-like odor may be noticeable. 

Activities are tentatively scheduled to take place February 7-9.  

*All dates and times are subject to change based on inclement weather and other operational factors.

Project Description:

The Newport Blvd. District 6 Trunk Sewer Relief construction project will replace an existing 60 year old regional sewer pipeline with a larger sewer pipeline to increase the sewer flow capacity and reduce the risk of spills.  Construction will take place along Newport Blvd. between Pacific Coast Highway and Industrial Way in the City of Newport Beach and Pomona Ave and 17th St in the City of Costa Mesa.
