This ordinance authorizes the Director of Public Utilities to enter into a contract with CDM Smith Inc. for professional engineering services for the Stormwater Remote Site Communication Network Upgrades project, C.I.P. Number 611661-100000, in an amount up to $97,757.00; and the Sanitary Remote Site Communication Network Upgrades project, C.I.P.

The City of Columbus, Department of Public Utilities (DPU), Division of Sewerage and Drainage (DOSD) has 95 sites that require monitoring and in some cases, control. DOSD utilizes a network system of radios and repeaters for communication and control of stormwater and sanitary sites. These systems also inform maintenance staff of any problems at these sites. Interrupted control or communication could potentially cause operational challenges which could contribute to Water-In-Basement (WIB) events or overflows to area streams and rivers. These sites include five stormwater remote sites and 23 sanitary remote sites. Some remote sites are large enough to have PLC-based monitoring and control which includes biofilters, stream gauges, gate structures, and floodwall structures. Smaller remote sites such as flow meters and level sensors utilize battery powered sensors, solar power, or above grade antennas.

Many of these sites also have a need for electrical improvements, PLC upgrades, component lifecycle replacement, and radio quality improvements.

The purpose of these projects is to evaluate and plan the needed upgrades for the DOSD radio network systems; to evaluate, identify, and address the necessary communication needs specific to DOSD's remote sites; and ensure that each of the remote sites continue to be an integral pa...
