Johnson � 1 <br />Controls <br />UuErade of the Process Controls for the Water Treatment Facility <br />Communication between the water treatment plant and <br />remote pumping stations is conducted through analog <br />phone lines. These lines have limited bandwidth and <br />therefore only a handful of parameters are passed from <br />the pumping stations to the water treatment plant. The <br />water treatment plant also has a limited range of control <br />signals it can pass to the well houses. The city leases <br />the phone lines at a considerable annual cost and <br />operating personnel are frustrated with grounding issues <br />and poor communication between the sites. <br />Furthermore, the analog system has become obsolete as <br />industrial process control moves toward fully digital <br />systems. Therefore, support for the existing system will continue to become more expensive. <br />Johnson Controls proposes to install a state of the art electronic supervisory <br />control and data acquisition ( SCADA) telemetry system to fully automate <br />communication between the water treatment plant and remote pumping <br />stations. Each site will have a programmable logic controller (PLC) to <br />monitor and control the equipment at that site and PLC's will have the ability <br />to communicate wirelessly with each other. The system's large bandwidth <br />can provide operators in the water treatment plant the ability to monitor and <br />control remote sites in near real time. Algorithms in the PLCs can optimize <br />system configuration to support water needs while minimizing energy use. <br />I` <br />BIM # <br />Process Controls Upgrade — Water Treatment Facility <br />WP2 <br />Process Controls Upgrade <br />• Install wireless SCADA telemetry system on the water treatment facility and remote <br />pumping sites <br />Risks of not implementing the recommendations <br />• Existing system equipment is obsolete — expense of maintaining and replacing parts <br />will continue to increase <br />• Loss of communication could cause a failure of water supply <br />• Frequent grounds on existing system result in IncR „f <br />tT... enefits <br />Remote monitoring and control of pumping stations <br />Ability to optimize system performance Increased range of parameters that can be communicated between sites <br />Page 21 City of St. Anthony Village <br />Performance Contract Analysis <br />NOT TO BE REPRODUCED OR PROPIUARY AND DISTR UTEO WITHOUT JOHNI <br />B SON CONTROLS' PERMISSION <br />
