Site work and new construction of a civil project in Sunnyvale, California. Conceptual plans call for the construction of a water / sewer project.

As originally envisioned in the Master Plan, this project entails implementing a facility that would store and feed fats/oils/grease (FOG) and food waste to the digesters. FOGs are a significant and problematic component of domestic wastewater. In order to avoid FOG buildup in pipelines and the treatment processes, grease loads will be trucked directly to the Water Pollution Control Plant (WPCP) for treatment. Decomposition of food waste in landfills generates greenhouse gases such as methane. When this project was initiated, it was assumed that digesting FOG and food waste would be economically beneficial only if excess digester capacity is used. It was planned that a FOG and food waste market analysis would be completed at the onset of this project. The estimated cost assumes the following major project elements: (1) FOG and food waste receiving program development; (2) 3,000 gallon per day FOG storage and feed facility with associated storage tank, grinder pumps, and feed pumps; and (3) 3,000 gallon per day emulsified food waste storage and feed facility with associated storage tank, grinder pumps, and feed pumps. Although the Master Plan contemplated digesting both FOG and food waste, it is now anticipated that the facility will be receiving mostly food waste since FOG is no longer as readily available. Since the approval of the Master Plan, the State has passed Senate Bill (SB) 1383 which establishes state targets to achieve a 75 percent reduction in the level of statewide disposal of organic waste by 2025. To achieve these aggressive reduction goals, municipalities are required to secure processing capacity and implement comprehensive organics diversion programs. As September 22, 2022, this project is currently in the FY 2022 - 2023 CIP. Funding for this project is allotted in the city's capital improvement plan for construction FY 2023 - 24. A firm timeline has not been established; however, construction is scheduled for Fiscal Year 2023 - 24. *Project information has been obtained through a public capital improvement plan (CIP). A CIP is a financial schedule for short- and long-range projects which is updated regularly. Information listed in the CIP often evolves based on funding availability and the project details, including timeline and value, are subject to change. The content management team will continue to pursue additional details as they become available.
