b. Capabilities and Features.
(1) 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 3,000 gallons
(11,340 liters). The ROWPU can be transported by rail, road, or air.
(2) (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 (round, Model No. 600-1) 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.
(3) 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 1/2 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.
a. To provide room for all operating components, material is stored inlayers (fig. 1-3 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.
b. 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 1-1/2 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 equipment removed.
