Phase II of a new water supply system for the entire Marina del Rey Water System was initiated earlier this year, with actual construction beginning on Admiralty Way May 19, county officials said.

The county of Los Angeles, the county Department of Beaches and Harbors, and the Waterworks District No. 29 in Malibu are partnered in the project.

The anticipated construction dates for this phase are from February/March through March/April 2012, according to county officials.

The anticipated start date of January 2011 had been stalled until April, followed by soil samplings and some more delays.

The project is expected to reach Fiji Way sometime around August, said project manager Julian Juarez of the county Department of Public Works, Waterworks Division.

Construction is scheduled between 9 a.m. and 4 p.m. to avoid peak traffic hours, and traffic cones and flashing message boards will be utilized to inform drivers in the construction areas, say county officials. Orange signs have been posted in and around Marina del Rey to notify motorists to use Lincoln Boulevard as an alternate route during the project.

The project plans to replace nearly 20,000 linear feet (approximately 3.8 miles) of pipeline over three phases in Marina del Rey. The first phase was completed in 2002 and was related to the city of Los Angeles connections, Juarez said in a 2009 presentation to the Marina del Rey Design Control Board.

The existing pipeline, constructed in 1962, has exceeded its service life of 40 years, according to the county. The pipe is expensive to maintain and the 10-inch and 14-inch diameter water mains are undersized to meet current demands, officials noted.

Installation of the 18-inch pipe will increase the reliability of the water system, and the new system will meet approved domestic and fire protection water demands, said Juarez. Two interconnections with the city of Los Angeles Department of Water and Power will be replaced that are currently used to meet current fire protection needs.

The existing system forms a loop around the Marina, and the main service connection is supplied through the city of Los Angeles, said county officials.

Phase II will install approximately 9,500 linear feet of 18-inch diameter water main along Admiralty Way, between Via Marina and Fiji Way.

Phase III will install approximately 9,800 linear feet of 18-inch diameter water main along Via Marina and Fiji Way. The existing water system will be abandoned in place.
