FOCUS Water supplies


hydrant for the next one, as it’s the most efficient for fill operation. Certainly the number, type and capacity of


vehicles are in the control of the fire department and its sponsoring agency, but the various roads, bridges and travel may not be totally compatible with weight limits, road conditions and so on, so planning for response is important.


There need to be some innovative, practical, economical and safe ways of providing the necessary services in general, and water movement in particular. A novel system of overhead water storage


tanks has been established throughout the county. These tanks were obtained as surplus, as underground petroleum tanks were replaced by fibreglass ones or were simply declared surplus to environmental requirements and business practices. These tanks are elevated, with increased foundation capacity as water weighs more than fuel, and they have capacities up to 20,000 gallons (75,708 litres), serving simply as static storage tanks. While they are supplied by a rural water


system, the supply is used only to refill the tank after use, and it may take hours to refill. The discharge spout has both an antiswirl fitting in the discharge elbow to keep the stream straight, and a flexible tube to prevent spray. Each tank is equipped with a heater, not used much in Mississippi, to prevent freezing. There is also a mechanical or electrical display to ensure passers-by that the tank is, indeed, full and ready for use.


A 3,500 gallon (13,248 litre) tanker can be


refilled in 49 seconds, by a simple turn of a valve, requiring no hose connection or great effort by personnel. Further, pumpers and tanks have an oversized fill tower on top of the vehicles. This 24in x 24in (0.6m x 0.6m) tower has a spring loaded trap door that opens when hit with a water stream, but closes otherwise to prevent
