Figure 1-2. Pumping Station
(1) SUCTION HOSE ASSEMBLY (1). The 6 in. X 10 ft, rigid-walled, wire reinforced hose assembly connects pump to
water source. Equipped with quick disconnect fittings for rapid installation.
(2) CHECK VALVE (2). Allows water to flow in only one direction. The check valve mounts on the discharge side of the
pumping assembly to prevent backflow to the pump from the TWDS system.
(3) TRAILER PUMP UNIT (3). Mobile pumping assembly rated at 600 GPM. Draws water from source or upline boost
pump and feeds reservoir or next downline boost pump. Fitted with suction and discharge elbows suitable for
connection to 6-inch boltless couplings. Utilizes noise enclosure for noise reduction. Refer to applicable technical
manual for operating procedures.
(4) DISCHARGE HOSE ASSEMBLY (4). The 6 in. X 20 ft collapsible hose assembly directs waterflow to hoseline.
(5) BUTTERFLY VALVES (5). The Butterfly valves isolate the pumping station when it is not in operation.
(6) BYPASS HOSE ASSEMBLY (6). The 6 in. X 75 ft collapsible hose assembly allows water to bypass the pump by
manually opening and dosing butterfly valves when station shuts down.
