Shimmick Wins US Water Treatment Contract

The San Francisco Public Utilities Commission (SFPUC) in the USA has awarded a contract to Shimmick Construction for the Sunol Valley Water Treatment Plant Expansion and Treated Water Reservoir Project.

Shimmick Construction has submitted the lowest qualified bid at $83.1m.

The project will involve construction of 17.5 million gallon circular treated water reservoir to function as a balancing reservoir to improve plant operation and water quality.

Construction is expected to start in mid-June and on completion the plant will sustainably treat 160 million gallons of water per day for up to 60 days following a seismic event.

The plant treats water from the two reservoirs in the East Bay’s Alameda Watershed.

The project is a part of the SFPUC’s $4.6bn water system improvement programme to upgrade the ageing Hetch Hetchy Water System.
