PLANNING AHEAD
A top objective of Zone 7 is to meet 100 percent of the Valley's current and future water-supply needs with high-quality water that surpasses state and federal standards.
In March 2005, Zone 7 began designing the Altamont Water Treatment Plant and Pipeline (AWTP&P). The project will treat State Water Project water delivered through the Delta to our service area. When complete, the AWTP&P will work in conjunction with Zone 7's existing Del Valle and Patterson Pass water treament plants and its well and distribution systems to meet the Valley's' drinking-water supply needs. The plant also will reduce water hardness by helping to meet more of the Valley's water demands with surface water, which does not contain as many minerals as groundwater.
Later, as the regon's population continues to grow and demand for water increases, the treatment plant can be expanded to its full capacity. Because the treatment plant and pipeline are designed to meet the water demands of future planned growth in Valley, the project is funded by connection fees on new development.
STRETCH OF PIPELINE IN LIVERMORE MOVES FORWARD
In April 2008, Zone 7 awarded a contract to Ranger Pipelines Inc. to build a 5-mile segment of pipeline within the City of Livermore, from Kitty Hawk Road to the vicinity of Vasco Road. Construction of this initial segment, which is part of the larger Altamont Water Treatment Plant & Pipeline Project, is complete as of October 2009.
Zone 7 is currently evaluating the timing of the larger project's future phases, including the treatment plant itself and the remaining 6-mile stretch of pipeline through unincorporated Alameda County west to Livermore. But independent of this larger project, the pipeline segment between Kittywawk and Vasco roads will have its own immediate benefits. By creating a loop within Zone 7's existing water-delivery system, it provides improved water-supply reliability for a portion of eastern Livermore in the event of emergency outages of water deliveries from the South Bay Aqueduct.
BACKGROUND
Zone 7 first identified the need for a new treatment plan in 1999 as part of its Water Supply Program. In 2001, the agency approved its environmental review for the treatment plant. In 2004, the California Department of Water Resources completed its environmental review of the
South Bay Aqueduct Improvement and Enlargement Project, which will supply water to the treatment plant. The cumulative impacts of the Altamont Water Treatment Plant, the South Bay Aqueduct Improvement and Enlargement, and the Altamont Pipeline projects were analyzed in the Altamont Pipeline final environmental impact report (FEIR), as required by the California Environmental Quality Act (CEQA). The Zone 7 Board of Directors approved the FEIR on February 16, 2005.
