The Utilities Department’s (UD), previously the Department of Water and Power, Water Reclamation Facility #1 (WRF1) generates Class A Exceptional Quality (EQ) and Class B (wet) biosolids from the wastewater treatment process.  Class B biosolids are dewatered to approximately 18% total solids and are temporarily stored at WRF1 prior to removal.  WRF1 currently generates approximately 43 wet tons of Class B biosolids per day and approximately 16,000 wet tons of biosolids per year. WRF1 has a National Pollutant Discharge Elimination System (NPDES) permit issued by the State Water Resources Control Board (SWRCB). One of the permit requirements is the lawful management of biosolids per Title 40 of the Federal Code of Regulations (CFR), Part 503.


The end-use management of biosolids includes the following, but is not limited to: collecting, transporting, composting, recycling, and disposal. All actions and activities must comply with all applicable federal, state, and local laws and regulations. The UD’s current contractor collects Class B biosolids from WRF1 and transports each load to a Synagro composting facility in Vicksburg, Arizona or Helendale, California.


Transport vehicles that are licensed to transport special waste are adequately equipped and fitted with seals to prohibit spillage or drainage.  The contractor must transport biosolids per Title 40 of the Code of Federal Regulations (CFR), Part 503. The contractor ensures that all drivers and vehicles hauling biosolids from WRF1 comply with current and future applicable California Air Resource Board (CARB) regulations and South Coast Air Quality Management District regulations.  The cost of compliance with these regulations shall be the sole responsibility of the contractor.



On June 30, 2021, the Purchasing Division issued RFP 21-084HC - Class B Biosolids End Use to collect, remove and dispose of or recycle Class B Biosolids.  The RFP was advertised according to Corona Municipal Code (CMC) 3.08.110 non-public projects formal bidding procedure requirements in the Sentinel Weekly and published on the City’s PlanetBids bidding portal. Twenty-seven firms registered with PlanetBids to provide transport services were notified of the procurement opportunity.  Ten firms, including four bid service companies, downloaded the RFP document. The City received one (1) proposal by the submission date of July 22, 2021.


Staff evaluated the proposal submitted by the contractor.  The evaluation was based on the following criteria:

The review panel carefully evaluated the single proposal received.  Synagro rated high in all areas of the listed criteria. UD can attest to Synagro’s quality of service as it is the City’s current contractor. Synagro has consistently provided reliable and quality service to the City. Synagro is the largest contractor of its kind for the area. While the Purchasing Department solicited multiple prospective bidders for this service, Synagro was the only one to respond. Staff recommends awarding the contract to Synagro as the best option for this service given its proven reliability, experience, expectations of service, and commitment to the environment. Synagro ensures all aspects of Title 40 of the Code of Regulations are adhered to, and it is held in high regard in this area as it ensures that all aspects of its services, from pickup to disposal, is compliant.


UD is currently in need of Class B Biosolids End Use Services to ensure that Water Reclamation operations can continue to run successfully. Therefore, staff recommends awarding the Agreement for Removal, Transportation, and Disposal of Class B Biosolids to Synagro-WWT, Inc.  Synagro’s Agreement will be for $1,800,000 per fiscal year for the initial two-year term ending June 30, 2023, with two (2) optional 1-year extensions All licenses and references for the contractor have been reviewed and verified by City staff.



Funding for the recommended action is included in the Fiscal Year 2022 Utilities Department Operating Budget. Funding in future fiscal years will be recommended through the budget process.
