Title
Resolution to Approve a Professional Services Agreement with Utilities Instrumentation Services SCADA for Sewage-Lift Station Radio Upgrades ($89,285.00)
Memorandum
Your approval is requested of a Professional Services Agreement with Utilities Instrumentation Services SCADA (UIS SCADA) in the amount of $89,285.00 to provide equipment, programming and installation services that support the upgrade of the Motorola radio system for remote communication and control of sewage-lift stations from the City's Wastewater Treatment Plant (WWTP).
Lift stations raise sewage to enable it to flow by gravity to the WWTP. The City operates and maintains eight sewage-lift stations at seven locations, seven in the City and one in Scio Township. The WWTP uses a radio system that provides the ability to control pumps at the lift stations and communicate alarms and data back to the WWTP. Continuous and reliable operation of the lift stations is critical to prevent sanitary sewer overflows to the environment or sewage backups into homes or businesses.
The existing radios were installed over 30 years ago and have steadily become less reliable. In addition, they are obsolete, as Motorola no longer provides replacement parts or support services for them. WWTP staff have relied on used and rebuilt parts obtained from third-party internet vendors for replacing failed components. These parts are becoming much more difficult to find and if a failed component could not be replaced, WWTP staff would be unable to receive alarms or control the lift stations remotely.
Using new Motorola units (ACE3600 RTU) is desirable as they will not require physical modification of the lift stations and are supported by Motorola. Two Motorola ACE3600 RTU's are currently part of the lift station radio system, one at the WWTP and the other at Scio Township's station, which they rehabilitated recently. By standardizing on this radio, the City will save costs on the equipment, installation and programmin...
