Consider approval of Resolution No. 08-110 authorizing award of contract for motor control center equipment for the Knox Wastewater Treatment Facility.

This contract is to provide programable logic controllers (PLCs) and Motor Control Center (MCC) equipment as part of ongoing project #08303.

Project #08303 is a comprehensive program to upgrade the automated controls of pumps and other operating equipment at the wastewater treatment plant.  The program includes installation of programable logic controllers (PLCs) which are computer chips which process data from pumps and other equipment related to the operating status of the equipment.  The PLCs then communicate electronically with the Motor Control Center (MCC) switches and the pumps/equipment are turned on/off or adjusted according to the programmed instructions included in the PLCs.  The PLCs also communicate with the plant-wide System Contol and Data Acquistion (SCADA) system to provide plant operators with information on the operating status of equipment.  The SCADA system is a computerized system which monitors and assists in controlling the optimum operation of the plant process units.  This project to upgrade the computerized controls of the plant operations will assist operators in optimizing the operation of the plant and to assure that regulatory treatment requirements are met.

Three bids for supply of this equipment were received.  The low bidder was Graybar at $66,419.21.
