The San Francisco Public Utilities Commission has advertised the $70-million San Joaquin Pipeline System � Western Segment project, which is part of the SFPUC�s $4.6-billion Water System Improvement Program (WSIP) to repair, replace, and seismically upgrade the aging Hetch Hetchy Water System.

The San Francisco Public Utilities Commission has advertised the $70-million San Joaquin Pipeline System – Western Segment project, which is part of the SFPUC’s $4.6-billion Water System Improvement Program (WSIP) to repair, replace, and seismically upgrade the aging Hetch Hetchy Water System.

WSIP includes more than 80 projects spanning six counties from the Central Valley to downtown San Francisco.

A pre-bid conference and bus tour of the project site is scheduled for Thursday, Sept. 30 at the Salida Library in Salida.

Bids will be opened at 2 p.m. on Oct. 21, with a contract anticipated to be awarded in November/December 2010. Notice to Proceed is expected to be granted in January/February 2011 with final completion in December 2012.

The SFPUC encourages all interested prime contractors to download prequalification packets at www.sfwater.org/prequalify. Prequalification is required to submit a bid on this project.

“We encourage contractors throughout the Central Valley to consider this construction bid opportunity and join us at the pre-bid conference in Salida at the end of the month to learn more about how you can partner with others to be part of the construction team,” says Chris Nelson, San Joaquin regional project manager for the SFPUC. 

The objective of the San Joaquin Pipeline System – Western Segment (HH-935B) contract is to construct a 78-in. diameter pipeline totaling approximately 11 mi at the western portion of the SJPL System. This is the second contract of three for the SJPL System project.

Expected trades on the project are earthwork; pipeline; structural steel; tunneling across highways, railroad, road and canal; and reinforcing steel and concrete work.

Human Rights Commission subcontracting goal requirement is 7% (MBE: 1%, WBE: 3%, OBE: 3%).

Meanwhile, in other WSIP news, the SFPUC unveiled plans on Sept. 7 for its proposed Westside Recycled Water Project.

The new wastewater reuse plant will be constructed in the city’s Golden Gate Park to treat secondary effluent from the Oceanside Water Pollution Control Plant (WPCP).

The recycled water treatment facility would include membrane filtration, reverse osmosis, ultraviolet light disinfection and treated water storage and pumping, all within a single building.

The project would produce and deliver up to 2 MGD, with peak deliveries of up to 4 MGD during the summertime, of treated water suitable for all recycled water uses approved by the state of California.

The estimated construction cost of the proposed project is $109 million, with construction planned for completion in 2015.

The SFPUC says that highly-treated recycled water would be delivered to a variety of customers through a system of pipelines, pump stations, storage tanks and reservoirs. The system would send recycled water from the treatment facility north to Lincoln Park & Golf Course to be used for irrigation; additionally recycled water would be used for various non-potable uses in Golden Gate Park, including those at the California Academy of Sciences.
