c. Pipelines and Pumps. Field pipelines may be used to carry water over
terrain that is inaccessible to trucks. However, pipelines are not generally used in the
field because of cost, construction time, availabiIity of equipment, and adaptabiIity to
field terrain. The standard pumping sets furnished with purification units do not develop
sufficient head for general pipeline use.
d. Tank Trucks and Trailers. Most company and battery-size units are
equipped with 2-wheel, 400-gallon water trailers that are towed behind 2 1/2 1/2-ton
cargo trucks. A trailer of this size is usually adequate for the needs of a company-size
unit. Larger units may be equipped with the 2 1/2-ton, 1,000-gallon water tank truck for
distributing water to its subordinate units.
e. Storage Containers. The following containers are authorized for the storage
of water in the field:
(1) Storaqe tanks. Engineer water points are equipped with collapsible
fabric water storage tanks with capacities of 500 gallons, 1,500 gallons, or 3,000
gallons, depending upon the size of the water purification unit. Figure 1-22 shows a
1,500-gallon collapsible fabric water tank mounted on a wooden ground platform.
