ITB_WRS260503_Installation_of_Centrifuge-Water_Reclamation_Facility_WRF_3_-_Exhibit_C_-_Poly_Blend___Metering_Pump_Dosage_Redacted.pdf

This Exhibit C document details the poly blend and metering pump dosage specifications for the City of Ocala Water Resources Department's Invitational Bid (ITB# WRS/260503) for the installation of a centrifuge system at Water Reclamation Facility #3. The exhibit establishes that WRF #3 currently operates at a dosage rate of 0.69 gallons per hour and consumes one 55-gallon drum of polymer blend every 10 operational runs. This supporting document provides critical operational baseline data necessary for bidders to understand existing chemical consumption patterns and to design compatible polymer mixing and metering pump systems for the new centrifuge installation. The mandatory pre-bid meeting is scheduled for Thursday, March 19, 2026, at 9:00 AM at the facility location, with bid submissions due April 7, 2026. Vendors must demonstrate a minimum of ten years of documented experience in domestic wastewater centrifuge design and installation, provide evidence of three completed projects, and possess OSHA 10/30 or equivalent safety training.

The specifications indicate that the new centrifuge system must integrate seamlessly with WRF #3's existing polymer dosing infrastructure while maintaining compatibility with current chemical supply and metering protocols. The project requires a turnkey installation with the vendor performing a minimum of 80 percent of work using their own forces, and award will be made to the lowest qualified bidder based on lump sum pricing. Vendors must provide a 5 percent bid bond along with Performance and Payment Bonds for the total bid amount and a three-year Maintenance and Guarantee Bond. Required insurance includes Commercial General Liability of $1,000,000 per occurrence/$2,000,000 aggregate, Commercial Automotive Liability of $1,000,000 combined limits, and Workers' Compensation per Florida statutory requirements. The maximum acceptable lead time is 26 weeks, and no estimated budget range or incumbent contractor information is disclosed in the solicitation documents.
