This is a service / maintenance or supply contract in Sunnyvale, California. Contact the soliciting agency for additional information.

The Water Pollution Control Plant (WPCP) Biosolids Processing project was initiated in 2009 to address the accumulation of biosolids (sediments) on the bottom of the WPCP Secondary Treatment Oxidation Ponds. This project provides funding for the removal, processing, and disposal of accumulated sediments from the Plant's Oxidation Ponds. The WPCP Biosolids Processing project also provides funding for the dewatering and beneficial reuse of anaerobically digested biosolids from the Plant's solids handling process until new solids dewatering facilities are constructed as part of the ongoing Sunnyvale Cleanwater Program. The Biosolids Handling scope of work provides for the removal of ponds solids by dredging and preconditioning before sending those biosolids to a centrifuge for dewatering. The WPCP Biosolids Processing project also provides funding for the dewatering and disposal of biosolids generated by the WPCP Anaerobic Digesters. After dewatering, those concentrated solids are hauled off-site for land application (beneficial reuse). Funding can also be used to clean digesters when the same contractor provides one or both of the previously mentioned services (pond and/or digester solids processing). This is a cost and logistical advantage for the City as much of the same equipment is used in the cleaning process. This project is included in the City of Sunnyvale's FY 2024-2043 Capital Improvement Program (CIP). Per the owner, as of May 6, 2024, this project is for services only and a contractor is under contract. *Project information has been obtained through a public capital improvement plan (CIP).
