5-ITB-26-00312 Attachment B - Falkenburg Process Diagram.pdf

This is a process flow diagram for the Falkenburg Advanced Wastewater Treatment Plant, prepared in October 2010 as an attachment to the Hillsborough County Board of County Commissioners' competitive sealed bid solicitation (ITB-26-00312) for centrifuge mobile sludge dewatering unit equipment rental. The diagram illustrates the complete wastewater treatment process at the Falkenburg facility, beginning with influent entering the headworks where grit and screenings are removed, progressing through an oxidation ditch and anoxic basin for biological treatment, and continuing through clarification, ultraviolet disinfection, and reclaimed water storage before distribution to customers. The solicitation seeks experienced and qualified suppliers to provide mobile centrifuge dewatering equipment rental services on an as-needed basis across multiple Hillsborough County advanced wastewater treatment facilities, including Valrico, Falkenburg, North West Regional Water Reclamation Facility, and South Central Regional facility. Bids are due July 27, 2026, and the contract term is five years with an estimated total contract value of $6,623,000.

The diagram's depiction of the Falkenburg facility's solids handling process—including the sludge storage tank, polymer addition, belt filter press, and associated pumping systems—demonstrates the infrastructure into which mobile centrifuge dewatering equipment must integrate. Bidders are required to provide evidence of liability insurance with Hillsborough County named as an additional insured, drug-free workplace compliance documentation, and W-9 tax forms. The County requires vendors to maintain insurance coverage and provide thirty days' written notice to the BOCC Risk Management Division of any policy cancellation or modification. The process diagram serves as a technical reference for bidders to understand the treatment facility layout and determine equipment placement and operational compatibility requirements.
