EQUIPMENT DESCRIPTION 1.14 EQUIPMENT CHARACTERISTICS, CAPABILITIES, AND FEATURES. 1.14.1 Characteristics. The TWDS consists of five or six pumping stations, a 10-mile hoseline segment, two storage assemblies, and two distribution points. The number of pumping stations is dependent on the terrain and distance over which the water must be transported. Smooth terrain requires five pumping stations with the sixth pumping station used as a spare. Rough terrain requires six pumping stations. Each pumping station consists of a 600 gallons per minute (gpm) pumping assembly, hose assemblies, 6 inch butterfly valves, check valve, and coupling clamps. One of three different 600 GPM pumping assemblies may be supplied with the TWDS, reference paragraph 1.16. Refer to applicable technical manual for a description of 600 GPM pumping assembly characteristics. The 10-mile hoseline segment is constructed of 6 inch by 500 foot hose assemblies. At intervals of every 1,000 feet a swivel joint is installed to prevent hoseline damage or chinking during hoseline packing. A pressure-reducing valve assembly can be installed to reduce water pressure between two pumping stations. The storage assemblies store water, tapped from the main TWDS hose line, which can be dispensed at the distribution points or pumped further down line as required. The storage assembly is a 20,000 gallon pillow tank. For a description of the 20,000 gallon pillow tank, reference TM 5-5430-226-12. Each distribution point consists of a 125 GPM pumping assembly, a hypochlorination unit, a network of hoses and 2 inch gate valves, and three types of water dispensing equipment. Refer to applicable technical manual for a description of the characteristics of the 125 GPM pumping assembly. One of three different hypochlorination units may be supplied with the TWDS, reference paragraph 1.16. Refer to applicable technical manuals for a description of the characteristics of the model 1955-3 and model A-506131 hypochlorination units. The model 1955-1 hypochlorination unit can chlorinate water at a rate of up to 100 gpm. A 2 inch hose network and 2 inch gate valves direct water flow from the hypochlorination unit to the manual dispersing stations. Chlorinated water can be dispensed from a hand held nozzle, an elbow valve, or a 36 gallon water storage bag. 1.14.2 Capabilities and Features. Can transport water at 600 GPM across level terrain. Can transport 720,000 gallons of water within a 24 hour period. Can be deployed and operational within 48 hours. 1.15 LOCATION AND DESCRIPTION OF MAJOR COMPONENTS. Figures 1-2 through 1-9 illustrate the major components of the TWDS. Tables 1-2 through 1-9 list the major components and provide a description of each major component. 1-3
