Section III. PRINCIPLES OF OPERATION
1-12. SYSTEM TECHNICAL PRINCIPLES OF OPERATION.
a.
General. The Tactical Water Distribution System (T'WI)S) described in this manual is configured
for maximum storage and distribution capacity. Your mission requirements will determine how
many of the system components must be connected and in what configuration. Additional
components are supplied with the system to adapt the TWDS to varying site and operational
needs.
b.
Triple Container (TRICON). Four tricons are supplied with the TWDS for storage of water system
components. Each container is equipped with standard ISO corner fittings to allow lifting by
overhead sling, and also permit coupling of three containers to form a 20- foot modular
assembly. Stacking of loaded containers is limited to a height of five containers. For additional
information on the triple container, refer to the applicable TM.
c.
Pumping Stations.
Five pumping stations are connected in series by 6-inch discharge hoses to form the water
transfer portion of the TWDS. Pumping station No 1 acts as the lead pump and is located at the
water source. Water is pumped from the source to pumping station No 2 located about two
mines downline. Pumping station No 2 boosts system pressure and feeds the water to pumping
station No 3. This process is repeated through the fifth pumping station. Pumping stations No 2
through 5 act as boost pumps to overcome pressure drops caused by hose line friction and rises
in field elevation.
Water flow through the pumping stations is controlled by opening or closing the butterfly valves
in the suction and discharge hoses. If a pumping station falls, water can be routed around the
failed pump through the bypass hose to keep the down line pumps primed.
Each pumping station includes a trailer mounted 600 gpm pump, check valve, butterfly valves
and 6-inch hose assemblies. Pump operation is controlled through a panel mounted on the unit.
For additional information on principles of operation for the 600 gpm pump, refer to the
applicable TM.
