Project Overview

South Coast Water District (SCWD) is installing a new recycled water distribution main in Golden Lantern, between Jeremiah and Stonehill Drives, correcting severe low-pressure problems within the vicinity of Stonehill Drive and Street of the Golden Lantern and the harbor area south of Coast Highway. We have had a significant increase in demands on the recycled water system, coupled with a section of small diameter main located within this area of the distribution system.

The construction is estimated to be completed in July 2019. 

Project Need

Although District staff have been working with recycled water customers to minimize demand peaks by staggering their scheduled irrigation times, there is an immediate need to complete this project, to maintain an adequate level of service and sufficient operating pressures in the recycled water distribution system. The District has placed a moratorium on allowing any additional recycled water users south of Stonehill Drive until these pipeline upgrades are completed. 

Recycled water is an essential part of the District’s drought-proof water supply. With uncertainty in hydrologic cycles, diversification in water supplies is more important than ever.


Work will begin in February 2019. Construction started north of Stonehill and will proceed north to Jeremiah Drive for approximately five months.

To lessen construction impacts to Dana Hills High School (DHHS) and the neighboring residents, construction will be limited to:

Mondays between 9 a.m. and 2 p.m.
Tuesdays through Fridays between 8:30 a.m. and 2 p.m. 
During the week of DHHS’s spring break, construction hours will be extended until 3:30 p.m. 
Work that does not require traffic control will take place between 8 a.m. and 5 p.m.

There will be no construction on:
2/18/19 – President’s Day
4/19/19 – Good Friday
5/27/19 – Memorial Day
6/6/19 - DHHS graduation.

Periodically, traffic may be restricted to one lane in each direction and street parking along Golden Lantern will be prohibited.

No parking signs will be posted 48 hours before being restricted. A weekly map of expected lane closures will be posted on Friday evenings at

The information will also be available on Facebook, Instagram, and Twitter.

Please check “no parking” signs for areas of restricted parking and allow extra time when traveling during construction hours.

Updates will be available at, on Facebook, Instagram, and Twitter.

Project Cost

The cost of the project is estimated to be $2.5 million dollars.
