9-ITB-26-00312 Attachment A - Valrico Process Diagram 1010.pdf

This is a process flow diagram for the Valrico Advanced Wastewater Treatment Plant, prepared in October 2010 for use in a solicitation by the Hillsborough County Board of County Commissioners. The diagram illustrates the complete wastewater treatment process at the Valrico facility, beginning with influent through headworks and grit and screenings removal, proceeding through an anoxic basin and oxidation ditch, then to clarification and UV disinfection before final discharge or reclamation. The diagram identifies all major equipment and process tanks including sludge holding tanks, filters, backwash systems, ultraviolet disinfection units, aluminum sulfate injection, return activated sludge (RAS) and waste activated sludge (WAS) handling, solids processing with polymer addition, and distribution to reclaimed water storage tanks and surface water discharge points. The diagram serves as a reference for bidders responding to the competitive sealed bid solicitation for centrifuge mobile sludge dewatering unit equipment rental, with bids due July 27, 2026, and establishes the technical context for equipment integration across Hillsborough County's advanced wastewater treatment facilities over a five-year contract period valued at $6,623,000.

The process diagram demonstrates the complexity of the Valrico facility's treatment operations and indicates the critical role that sludge dewatering equipment would play in solids handling and waste management. The diagram, provided as Attachment A to ITB-26-00312, enables potential bidders to understand the existing infrastructure and operational requirements at one of four county facilities where mobile centrifuge dewatering units would be deployed on an as-needed basis. This visual reference is essential for vendors to assess equipment compatibility, integration points, and logistical considerations for servicing the Valrico facility alongside Falkenburg, North West Regional Water Reclamation Facility (NWRWRF), and South Central Regional (SCR) facility locations.
