CDM to Complete Design-Build Delta Water Supply Project
October 21, 2009
STOCKTON, CALIFORNIA—CDM has been selected by the city of Stockton, California, for the second stage of the Delta water supply project. This design-build effort will provide a new supplemental water supply for the Stockton metropolitan area by pumping water from the Sacramento-San Joaquin Delta to a new state-of-the-art surface water treatment plant.
Having successfully executed the project's first stage of preliminary design, CDM has signed a $166 million contract amendment to complete 65-percent design drawings and construct the facilities. Project components include nearly 12 miles of raw water pipelines, more than 6 miles of treated water pipelines, and a 30-million-gallon-per-day water treatment plant.
According to Paul Meyerhofer, CDM senior vice president and project manager of the Delta water supply project, "The city of Stockton is committed to sustainable building practices, so several green features and methods will be incorporated into the project." The new water treatment plant's administration and operations building has been designed to achieve Leadership in Energy and Environmental Design Silver certification. Sustainable elements of the project include:
- Building features: Roofing materials that reduce heat absorption, efficient exterior lighting, parking stalls for alternative fuel vehicles, and low-emitting materials
- Water efficiency: Non-potable water and micro-irrigation systems for a 50-percent reduction in irrigation water use, and water-efficient toilets and urinals for a 20-percent reduction in water consumption
- Energy and atmosphere: Ozone-safe heating and air conditioning systems, operable windows for reduced energy loads, and solar panels to provide 50 percent of the building's electricity
- Materials: Construction debris recycling, storage of unused and excavated soil for future use, and recycled and Forest Stewardship Council-certified products for construction
CDM's portion of the Delta water supply project will generate more than 550 new jobs and infuse more than $70 million into the local economy through the use of local labor and materials. Construction of the facilities is scheduled to begin in October 2009, with completion planned for February 2012. At that time, CDM will perform 1 year of commissioning to ensure that the plant meets water quality and performance requirements.
