Capabilities and Features.
Flow systems within the ROWPU process raw water to make it drinkable. Special pumps, controlled by a
built-in control panel, move the water through the ROWPU to produce as much as 10 gallons (37.8 liters) of drinking water
per minute. This water is stored in a collapsible tank that can hold up to a total of 1,500 gallons (5,670 liters) or 3,000
gallons (11,340 liters). The ROWPU can be transported by rail, road, or air.
(Army) The flatbed cargo trailer and frame is designed to provide a mobile platform for the ROWPU. The
trailer, when being transported by road, is towed by a towing vehicle through a lunette/pintle hookup. The trailer has four
leveling jacks (square Model No. 0996109001 ) with swivels, one on each comer, and is equipped with a spare wheel and
tire carrier. The trailer incorporates service brakes which are air-actuated and operated from the towing vehicle through an
integral set of hoses. The trailer brake system also includes emergency and automatic parking brake functions that are
activated when the air hoses are disconnected from the towing vehicle. An air tank is installed for the purpose of reserving
air for this system when the trailer is disconnected from the towing vehicle. A 24-volt electrical system, consisting of one
composite blackout-stoplight assembly, and two stoplight-tail light assemblies, is installed on the trailer. Power is supplied
through a cable connected to the electrical system of the towing vehicle. The trailer suspension consists of two axles in
tandem, supported on leaf springs attached to a trunnion axle. The frame houses the ROWPU and is capable of being
separated from the trailer and transported or air lifted as an independent unit.
The Army and Marine Corps units are essentially the same except that the Marine Corps ROWPU is
mounted on a skid and does not incorporate a generator.
LOCATION AND DESCRIPTION OF MAJOR COMPONENTS. The Army ROWPU is 18 feet (5.5 meters) long, 8
feet (2.4 meters) high, and 8 feet (2.4 meters) wide. It weighs about 8 ½ tons (7.71 metric tons), including the generator
set. Figure 1-3 shows the ROWPU from the top with its canvas cover removed. Take a close look at how all the
necessary operating equipment is stored on the trailer for transport and shipment.
The Marine Corps ROWPU is 9.5 feet (2.9 meters) long, 5.6 feet (1.7 meters) high and 6.9 feet (2.1 meters) wide. It
weighs about 3.65 tons (3 metric tons). Figure 1-4 shows this ROWPU from the top with the canvas cover removed.
To provide room for all operating components, material is stored in layers (fig. 13 and 1-4). The top layer
consists of rolled-up (suction) hoses on top of two folded water tanks. Stored between the tanks is a sledge hammer and a
collapsed telescopic aluminum paddle. Next to the tanks is a stack of five plastic pails with chemical names on their sides.
On the same side of the ROWPU you will find two storage boxes fastened with a strap under the tanks. The boxes contain
various chemicals, tools, and installation items. Nine sections of suction hose are stored on the side of the frame.
In the second layer you will find two raw water pumps and a backwash pump (fig. 1-5 and 1-6). The pumps
are covered with canvas and strapped down. A distribution pump is located at the rear of the unit, next to the generator
(Army ROWPU only), not shown here. Army ROWPU includes a portable step strapped down with distribution pump. On
the right side are 1 ½ inch and 2-inch diameter discharge (canvas) hoses, rolled-up. A raw water float is in the center of
the ROWPU next to two nuclear, biological, chemical (NBC) cylinders. Figs. 1-7 and 1-8 show ROWPU with operating
