TM 10-4610-237-12 1.10 LOCATION AND DESCRIPTION OF MAJOR COMPONENTS. (REFER TO FIGURE 1-1) 1.10.1 125 GPM Pump Connection Kit. The connection kit consists of hoses and valves needed to connect the 125 gpm pump and in line check valve to the water tank. The 125 gpm pump serves two purposes. It is used to pump water from the water source as needed to fill the water tank. The pump also is used to pump water out of the single tank to supply the remaining components in the water system. The in line check valve prevents back flow of water through the 125 gpm pump during pumping operations. 1.10.2 125 GPM Pump. The 125 gpm, engine driven, centrifugal pump is skid mounted with handles at both ends to aid lifting and positioning. Refer to the applicable TM for location and description of major components on the pump. 1.10.3 Single Tank Connection Kit. The single tank connection kit consists of hoses, valves and tees needed to connect the 20K collapsible water tank to the water system. Hand operated gate valves serve two purposes. They are used to control the flow of source water pumped by the 125 gpm pump into the tank. The gate valves are also used to control water flow out of the tank for pumping by the 125 gpm pump to the water system. 1.10.4 Tank. The tank can store up to 20,000 gallons of potable water. The tank expands and becomes pillow shaped when filled. Handles on the sides of the tank aid movement and positioning of the tank during setup and take down. The tank is supplied with a ground cloth, couplings, vent tubes, elbows and a drain valve. Refer to the applicable TM for location and description of major components on the water tank. 1.10.5 2-Inch Hose Connection Kit. The connection kit consists of hoses, a tee, a gate valve, and couplings needed to connect and dispense water to trailer mounted water tanks (water buffaloes) and other large containers. A hand operated gate valve is used to control water flow to the transport container. One 2-inch hose connection kit is used in the water system. 1.10.6 Hose Nozzle Connection Kits. The connection kits consist of hoses, tees, couplings, reducers, valves and distribution nozzles to dispense water to large portable containers. Hand operated gate valves and distribution nozzles are used to control water flow to the containers. Each nozzle is equipped with a swivel coupling to ease operation. Nozzle stands are provided to prevent dirt, sand and contamination from entering the distribution nozzles. Four hose nozzle connection kits are used in the water system. 1.10.7 Hypochlorination Unit. The hypochlorination unit treats the water supplied from the 125 gpm pump with hypochlorite solution. The solution is injected into the water based on the water flow rate. The water must be tested and the unit adjusted to provide the correct ratio of hypochlorite solution as required by medical personnel. Refer to the applicable TM for additional information on the hypochlorination unit. 1-4
