To Satisfy the United States Environmental Protection Agency’s (EPA) National Pollution Discharge Elimination System (NPDES) permit, wastewater must be treated to achieve regulatory water quality standards. The RWQCP treatment processes require the use of various chemicals to achieve water quality objectives.
DISCUSSION:
On January 28, 2025, the Purchasing Division of the Finance Department issued Request for Proposals (RFP) No. 2441 through the online bidding system, Planet Bids, soliciting chemical vendors for Polymeric Flocculant. A mandatory pre-proposal meeting and pre-trial jar testing was held on February 11, 2025. Three vendors, Solenis LLC, Finley Industrial Services, and SNF Polydyne, Inc., were in attendance. Each company provided a sample of their Polymer Totes, which were dropped off on site at the RWQCP on February 18, 2025.
RFP No. 2441 closed on March 18, 2025, and a total of two proposals were submitted.
On April 3, 2025, under the direction of the Purchasing Division, an Evaluation Committee was convened, comprising three City staff members. Each team member independently reviewed and scored the proposals. Evaluations were conducted based on the criteria listed in Table 1.
