Elevations The high water elevation of the proposed elevated water reservoir should be rasied 6.5 feet . . above the high water level of the existing tower, to an elevation of 1054.5. This elevation will provide satisfactory pressures in the City and will match the high water level of the Lino Lakes elevated tower system that is interconnected to Centerville' s system. The approximate top of the foundation at the base of the reservoir will be approximately 906.0. Therefore, the height to the high water level of the water tower is 148.5 feet. Trunk Water Mains A short trunk water main from existing piping to the new tower site is required in order to connect the proposed tower to the trunk distribution system. The 10" and 12" trunk water mains along 20th A venue will provide a convenient connection to the existing system and is sized accordingly. A few water services to customers may need to be temporarily discontinued during the connection to the tower. Telemetry The existing telemetry system uses a dedicated phone line from the existing tower and well to a City Hall master system and dialer. Upgrading of the telemetry system should be evaluated at the time of the tower design. A new radio master telemetry system could be centrally located at the Public Works building next to the new tower. The new tower and the wells could be equipped with antennas to send radio signals to the master system. The telemetry system could also be updated to receive signals from all of the lift stations for monitoring and record keeping purposes. The entire radio telemetry system would allow easy monitoring of all systems in the City without relying on a telephone company for service and the radio system would eliminate the monthly charges imposed for the use of the dedicated lines and phone service. Costs for upgrading and updating the telemetry system have not been included in the cost estimate for the new tower. Water Tower Feasibility Report 17
