Irvine Ranch Water District contractors are installing pipeline corrosion protection systems at eight locations along Laguna Canyon Road and Quail Hill Parkway. The work is a necessary part of the maintenance of local drinking water pipelines.

Project summary: The project involves drilling and excavation work, along with the installation of a new rectifier and anode well at eight locations, (noted in red in the map).

When: Mid-October, 2018, through mid-January, 2019.

Construction hours:

  • 9 a.m. to 3 p.m. Monday through Friday (for roadway construction).
  • 7 a.m. to 7 p.m. Monday through Saturday (for drilling).

Project impacts: Some traffic lanes and sidewalks will be closed during various phases of construction. Bicyclists and motorists will be required to share the road in some construction areas. Alderwood Elementary students who walk to school are advised to take alternative routes to campus when their usual course is affected by construction.

No interruption of domestic water service is anticipated. Recycled water service for irrigation might be shut off for up to 48 hours. Affected customers will be notified at least 24 hours ahead of time so landscaping can be watered in advance.

Questions: For more information, contact the IRWD Public Affairs Department during normal business hours (8 a.m. to 5 p.m.), at 949-453-5500, or After-hours questions should be directed to IRWD's customer service line at 949-453-5300.
