Construction Notice: Pipeline 4 Maintenance

Construction Notice for SDCWA Pipeline 4 Maintenance by San Diego County Water Authority.

Emergency Pipeline Maintenance from SDCWA

Next month, the San Diego County Water Authority (SDCWA) will perform a 21-day emergency pipeline repair to their regional Pipeline 4, in an area South of Highway 76 at Dulin Road. To facilitate the construction, Metropolitan Water District's Aqueduct 2 will be shutdown. The major service connection delivers treated water from Lake Skinner Treatment Plant to southwest Riverside County and northern San Diego County, and the shutdown will impact several retail water agencies including Rainbow Water. 
Rainbow Water will make internal adjustments to deliver water from other Metropolitan connections during construction and the shutdown is not anticipated to impact delivery of water for our customers. The recent completion of new pump stations in the southern region of the district's service area will allow for greater water supply reliability during emergency events.

Project Schedule  Start: June 1    End: June 21 

How Rainbow Water is Preparing

  • Reservoirs and storage tanks are being pre-filled throughout the service area before the shutdown.
  • The Board approved an interconnection
  • agreement with Fallbrook Public Utility District to share water supply should the area see peak demands during this shutdown.

What You Can Do to Prepare

As summer approaches and the heat increases, this is an ideal time for customers to practice water efficiency and reduce water waste. You can help by:

  • Being diligent about all water use during the shutdown period, eliminating all wasteful use.  
  • Updating irrigation systems to water in the early morning or evening to reduce water evaporation and water only as needed.
  • Hold off on discretionary water use (filling pools) until after June 21.
