Pipe Bursting Construction Starting Week of November 27

Post Date:11/22/2017 9:00 AM


Work will take place Sunday, December 3 between the hours of 8 a.m. and 6 p.m.  

Extended work hours required for pipe bursting operation

Pipe bursting activities began this morning, to replace a 15-in pipe with a 22-inch HDPE pipe along Newport Blvd. just south of Hospital Road in the City of Newport Beach. Unexpected soil conditions have limited the production rate significantly which are requiring the operation to continue until the pending segment of pipe is installed. At this time, it is unclear how long this process will take and there is a possibility the work will need to continue overnight. Stopping the operation is not an option as it would require an excavation to rescue the machine. Sound blankets will be installed around the air compressor area to reduce the noise level.

We apologize in advance for this inconvenience and assure you, we are working diligently to get this issue resolved.  If you have any questions, please contact our Control Center at 714-593-7025.


 Work is currently taking place along northbound Newport Boulevard between Coast Highway and Hospital Road. The Newport Boulevard/Old Newport Boulevard full ramp closure will remain in place 24 hours/7 days a week until December.

Crews are preparing for new sewer pipe installation using the pipe bursting construction method.  Pipe bursting involves a lot of preparation and post-bursting work.  Actual pipe bursting is anticipated to start the week of November 27.

No work will take place on Thanksgiving or the day after Thanksgiving.

What is Pipe Bursting?

Pipe Bursting GraphicPipe bursting is the replacement of the old pipe by fragmenting the existing pipe with a bursting head tool and installing a new pipe in its place.  The new pipe is placed in the same alignment as the existing pipe.

For this project, over 900 feet of old clay pipe will be replaced with a new and larger diameter High Density Polyethylene (HDPE) pipe that will last over 50 years. A temporary bypass pumping system will be in place and there will be no disruption to sewer service.  

 What to Expect

  • Equipment and vibrations close to the work areas.
  • Increased construction noise and activity may be noticeable, especially during actual pipe bursting activities.
  • When the bypass pumping system is turned on for approximately 2 weeks:
    • 3-4 parking spots will need to be taken.
    • Crews will be on-site 24/7 for continuous monitoring.

Work Hours 

Work hours are 7 a.m. - 6 p.m., Monday through Friday.  Extended work hours and some weekend work will occur as needed.
