The system utilizes remote <br />programmable controllers at each water production site and a central <br />computer system located at the City Yard to remotely operate wells, pumps, <br />and reservoirs. Uninterrupted reliability and functionality of this <br />system is required to maintain operation of the water system. The <br />existing system was installed by Transdyn Controls, Inc. in 1992 and was <br />upgraded in 2000. <br />Due to the age and obsolescence of the existing hardware and software, the <br />programmable logic controllers located at each of the City's 38 water <br />production facilities must be replaced. New central computers located at <br />the City Yard are also required to provide fail-safe protection and <br />uninterrupted operation of the water system. <br />The proposed upgrade project also includes the installation of a radio <br />based communications system. This system will replace the current leased <br />telephone line system, providing increased reliability and will result in <br />an annual cost savings of approximately $40,000 in phone charges. <br />The current system provided by Transdyn has functioned since 1992 without <br />failure. Staff recommends that Transdyn Controls, Inc. be retained to <br />provide the required upgrades for a continued uninterruptible and <br />functional system. <br />25F-1 <br />
