1-10. LOCATION AND DESCRIPTION OF MAJOR COMPONENTS - cont.
(3)
Pressure Relief. Valve Relieves excessive water pressure from pumping station.
Pressure relief valve opens when water pressure exceeds 200 psi.
(4)
Discharge Hose. 6-inch collapsible hose distributes water through pumping station.
(5)
Butterfly Valves. Hand operated valves control water flow through pump station. Valves
can be used to isolate pump from hose line during pump maintenance or replacement.
j
Suction Hose. 6-inch noncollapsible hose supplies water to the pumping stations. Suction
hoses are installed on the suction side of each pump to prevent collapse of the hose under high
suction pressures.
j
Storage Assemblies. Two storage assemblies are supplied with the TWDS. Each assembly
consists of hoses, gate valves, tees and a 20K collapsible fabric tank. The storage assemblies
are used to store water for use by the distribution points. Major components of the storage
assemblies include.
(1)
4-inch Gate Valves. Hand operated gate valves control water flow from the main hose
line to the 20K collapsible fabric tanks.
(2)
20K Collapsible Fabric tanks. The tank can store up to 20,000 gallons of potable water.
The tanks expand and become pillow shape when filled. Handles on the sides of the
tank aid movement and positioning of tank during setup and take down. Each tank is
supplied with a ground cloth, couplings, vent tubes, elbows, drain valve and repair kit.
Refer to the applicable TM for location and description of major components on the water
tanks.
k
Distribution Point. Two distribution points are used to treat and dispense water from the
storage assemblies. Nozzle stands are provided to prevent dirt, sand and contamination from
entering the nozzles and elbow valves. Each distribution point consists of the following
components.
(1)
125 gpm pump The 125 gpm, engine driven, centrifugal water 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.
(2)
Hypochlorination Unit. Self contained, skid mounted unit operated by system water flow.
Automatically chlorinates water being dispensed. Refer to applicable TM for additional
information on the Hypochlorination unit.
(3)
Elbow valve Handwheel operated valve installed at the end of the distribution point
discharge hose. Quick disconnect couplings on valve permit coupling to tanker trucks or
other water transport vehicles.
(4)
Distribution nozzle Hand operated nozzle dispenses water to small containers.
