Seawatch lining process map 070918

IRWD is upgrading 4,500 feet of recycled-water pipeline that runs along the Coral Cay/Seawatch fire access road between the Crystal Cove and Pacific Ridge communities in Newport Coast. The pipeline delivers the outdoor water used for irrigating the landscape on HOA property and at some homes in the upper elevations of the Crystal Cove community. This work will prevent leaks in the line, which have caused outages and required repairs in the past.

To minimize construction impacts, the District will install a cured-in-place lining inside existing pipe. Once installed, the CIPP liner will extend the length of the original pipe as a continuous, watertight “pipe within a pipe.” Some pipeline sections will be replaced along an existing trench line on a circular staging area located at the western end of the fire road.

Water shutdowns: Recycled water service for landscape irrigation will be shut off June 7 and 8, 2018, at which point drinking water will be connected to the irrigation lines throughout the duration of the project. Recycled water customers will continue to pay recycled water rates during this period. There is a slight possibility that drinking water service in the Crystal Cove area outlined in the project's Water Shutoff Area Map below may be disrupted for a six-hour period during construction. Should that need arise, all affected residents will be notified prior to any planned shutdowns.

Construction will begin with an initial cleaning of the existing pipeline, removing all debris, roots and other materials that would prevent the proper installation of the liner. The interior of the pipelines will then be carefully inspected to determine the location of any condition that may prevent the proper installation of the line into the pipeline. Following installation, a 24-hour testing of the lines will be conducted to ensure proper installation.

Project Updates+

Week of Nov. 19, 2018:

Contractors next week will be applying a slurry seal to the roadway along the entire length of Seawatch. All residents of Seawatch and Needlegrass are advised to park along Pacific Mist on the day that work will be done. 

Week of Nov. 12, 2018:

Final paving is scheduled for this week.

Week of Oct. 29, 2018:

Six hundred feet of pipeline was installed in an open-cut excavation where a second pressure test failed. Backfilling and paving will begin soon.

Week of Oct. 15, 2018:

Trench repairs are underway to install a new segment of pipeline from the beginning of the alignment to access pit No. 9, following a second unsuccessful pressure test.

Week of Oct. 8, 2018:

Pipeline repairs are underway to address failures in the pressure testing of the pipeline.

Week of Sept. 17:

A pressure test of the CIPP pipeline resulted in damage to a segment of the pipe which will have to be replaced.

Week of Sept. 10, 2018:

The recycled water bypass is expected to be removed and the recycled water pipeline put back in service by Sept. 25.

Week of Aug. 27, 2018:

Contractors will begin repairing deficiencies in the liner next week. The bypass is expected to be removed and recycled pipeline put back in service by the end of September.

Week of Aug. 12, 2018:

Some deficiencies in the line were discovered following the CIPP process. The contractor is replacing an affected section of pipe and other possible applications to correct the deficiencies are under review.

Week of July 30, 2018:

Installation of the cured-in-place pipeline has been completed, and hydrotesting is underway.

Week of July 23, 2018:

Work has been ongoing to install a cured-in-place pipe inside the existing recycled water pipeline running along Seawatch and the fire access road east of Coral Cay. This portion of the project should be completed soon.

Week of July 9, 2018:

A cured-in-place pipe (CIPP) will be installed inside existing recycled pipeline running along Seawatch and the fire access road east of Coral Cay. The process includes the installation of a resin-saturated tube, which requires the use of power generators along the pipe route during the installation and curing process, which will take place from 8 a.m. to 6 p.m. Monday through Friday, July 11 through July 25. Residents may notice the low drone of generators and occasional hissing from the release of pipeline valves during this phase of construction. A slight odor of resin might be noticeable near the pipeline during the process.

Week of June 4, 2018:

Access pits are being excavated and segments of PVC pipe are being installed. A planned irrigation water shut-off for June 7-8 was moved to June 12.

Week of May 28, 2018:

Potholing has begun along Seawatch and the fire access road.

Week of May 21, 2018:

Construction is scheduled to begin on Monday, May 28 with potholing along Seawatch and the fire access road. Recycled water for landscape will be temporarily shut down on Thursday, June 7 and Friday, June 8 and then replaced by domestic water for the duration of the project. Recycled water customers will continue to be charged recycled water rates for irrigation during construction. Property owners irrigating with recycled water are advised to double their usual irrigation time on the day before the June 7 and 8 shutdown, and to avoid planting the week before the outage.

Week of March 12, 2018:

A construction award for the project was approved on March 12. Construction is scheduled to begin in April.

Week of March 5, 2018:

A bid for the project is expected to be awarded in mid-March 2018.
