Projects, Milestones, Timing
The relatively small size of the main plant area and the need to maintain continuous operations 24 hours per day, seven days per week, largely determines the phasing of the Sunnyvale Cleanwater Program implementation. Some existing facilities must be decommissioned and demolished to create space for construction of new facilities, and no more than two large contractors can work on the site simultaneously. Other factors that determine the overall proposed schedule include cost, the timing of future regulations (such as new discharge requirements for nutrient removal), and projected increases in flows and loads.
The Program broke ground on Package 1 of the Headworks and Primary Treatment Project in 2017. A dozen capital projects that make up the first three phases of SCWP will be continuously under construction until 2027. At the end of this period, the Plant will be fully-protected from tidal flooding, with new technology and the existing ponds operating in parallel. It will also be processing fats, oils, grease, and food waste, as well as sewage.
