The Work includes installation of permanent sanitary sewer flow meter stations at eighteen (18) sites in the Metro Wastewater Reclamation District’s TransmissionSystem. Facilities to be installed at each site generally include a concrete equipment pad, an above grade flow meter cabinet, buried conduits/cable to supply power to the cabinet, buried conduits/cable to connect equipment in the cabinet to the flow meter sensors located inside the manholes, and flow meter sensors mounted inside the manholes. The flow meter cabinets will house a flow meter data logger; a Metro Wastewater Reclamation District data logger and radio telemetry equipment; electrical power distribution equipment; and backup power batteries.
Fifteen (15) of the eighteen (18) sites require new flow meter station installation. Of these sites, nine (9) will meter flow in a single manhole, while six (6) will meter flow from two manholes. Of these sites two (2) are equipped with solar power equipment, and thirteen (13) are equipped with utility power service from Xcel Energy.
Three (3) of the eighteen (18) sites are at existing meter station locations where the meter cabinets, flow meter equipment, radio telemetry equipment, and power supply equipment already exist. These sites require replacement of the existing flow meter sensors and equipment with new flow meter sensors and equipment furnished under this Contract.
