The County distribution system does not have many dedicated large trunk mains, resultingin the use of several smaller mains. Currently, a small number of transmission mains supplythe developing portions of the County east of Interstate-75. A new large transmission mainin this area of the County will assist in meeting demands in the future.Additionally, in newly developing portions of the County that are not yet built to full capacity,the new infrastructure being installed is intended to meet future build-out conditions. In theinterim, this infrastructure is over-sized for the small number of residents currently living inthese areas. This situation is currently being remediated via regular hydrant flushing instrategic locations, as well as by the installation of automatic flushing systems in the mosthighly affected locations.2.4.2 Pump StationsThe County water system contains 6 pump stations, 2 of which can operate as either a highservice or a booster pumping station. The remaining 4 pumps stations operate as highservice pumps stations only. The location of the original pump stations (Numbers 1, 2, and3) correspond to the needs of the system prior to introducing new water sources such asthe Carlton WTF and Peace River supply. As the water area expanded and demands grew,the operational needs of the system changed and some pump stations became obsolete.2.4.2.1 Pump Station Location and OperationThe locations of the 6 pump stations are shown in Figure 2.13, and their operationalstrategies are described below. Pump curves and specific information regarding pumps,motors, and flow set points for pump stations can be found in Appendix G.It should be noted that during initial inquiries to obtain pump curves, County staff stated thatpump curves were not available. Subsequent inquiries to the County resulted in pumpcurves for most individual pump stations. Certified pump curves that were received areincluded in Appendix G. However, some certified pump curves were not obtained from theCounty (Pump Station No. 3 and Carlton WTF high service pumps). Therefore, these pumpcurves were obtained based on collected field data, such as model, horsepower, andimpeller size, which was matched with cut-sheets from the associated manufacturer.Consequently, the pump curves included for these pumps are not certified and requireverification prior to being used in hydraulic modeling or for other purposes.FINAL - August 31, 2005 44H:\Client\SAR Co_SAR\6873C00 WATER SUPPLY MASTER PLAN UPDATE\Deliverables\TM 2 - Water System Assets\Final\TM2 Final.doc
