TEXAS 77520 - PHONE (713) 422-8213 . - December 10, 1975 Honorable Mayor Pro Tem and City Commissioners City of La Porte P.O. Box 1115 La Porte, Texas 77571 INSTRUMENTATION OF WATER SYSTEM At the request of Mr. Morton we have conducted a study of the entire water system and have developed costs for four grades of instrumentation. The different types have various advantages, costs and degrees of control. All four use leased telephone wires for transmission of signals. There are two grades of telephone wires and the number of pairs and lease cost varies considerably with different systems. . the most expensive system is one in which all functions at all water system facility locations including Fairmont Park can be both indicated and con- trolled from a central point. Specifically, this means the well pumps and boosters can be turned on or off at all locations either automatically or manually from the central panel which would probably be located at the City Public Works Building. Each site would also have local control available. The status of the tank levels and pump operation would be transmitted and indicated by lights on a panel. The initial cost of this system would be about $50,000.00 plus a lease cost for the telephone wires at about $30.00 per month. This rather sophisticated system requires only one high quality line patr for each installation. A less expensive system will indicate the status of all equipment and tank levels by means of lights on a central panel, but would have control only at the site of the facility, i.e., no remote control would be available. The cost of such an installation would initially be about $30,000.00 plus the same approximate $30.00 per month leased telephone line cost. This system could be expanded at some later date to the full remote control system since all the components are compatible. Additional equipment would be required, but no additional leased telephone wires would be needed. A much less expensive version of the second described system having the same status indication at a central point and with local control only, . . .t. "
