3-6.3 If a berm drain is installed, as recommended, it should be laid in a hand-cut trough after the first layer of berm is
placed and before the second layer is placed. Care must be taken, of course, to avoid damage by the equipment
constructing the berm. This can best be handled by not installing the valve until after the berm is completed and giving
the pipe ends plenty of cover. When the drain valve is installed, it should be left closed, and preferably locked closed, or
the integrity of the berm has been compromised.
3-6.4 If the installing authority decides to install construction grade polyethylene sealing sheets, they should be installed
after the pad and berm are completed. After the joints of the sheeting are sealed, a light layer of soil (without rocks) may
be spread to protect the sheeting and hold it in place. See para.'s 2-3.2a and 2-3.2c.
CAUTION
Tank pads must be free of rocks, sticks, and sharp objects to prevent tank damage.
CAUTION
Berm drain valve must be installed in the closed position and opened only to drain the berm
when necessary,
CAUTION
If fabric collapsible tanks are installed on a general slope in excess of 30, they may tend to
creep in the direction of the slope. Install as shown on Fig. 2-10.

Pads for Other Equipment
3-7.1 To the extent possible, all operating equipment should be set on virgin or cut soils rather than fill. If a filled area
cannot be avoided, it must be well compacted. This is particularly important for the pumps.
3-7.2 If available, it is recommended that the areas on which equipment is placed be covered with a 4-6 inch layer of
coarse gravel or crushed rock. The gravel or crushed rock should extend out and around the equipment for several feet.
This will provide a high and dry area from which to operate and maintain the equipment.
3-7.3 The same practice of placing coarse gravel or crushed rock area at and around often operated valve stations is
recommended as well.
SECTION III EQUIPMENT RECEIPT
3-8 General
All equipment and materials are shipped to the receiving port or staging area in accordance with the U.S. Army's
transportation plan. All items are boxed or crated in accordance with a plan that provides for the full identification of what
is in the box or crate. Each container contains overpacked documents which further confirm the identity and gives
instructions as to treatment arid,/in the case of hose, pipe, fittings and valve assemblies, where in the TPT the items go.
Because of the care given in packaging and identification, it is generally recommended that the containers be transported
directly from the receiving port or staging area to the actual erection site prior to opening. The materials are then
removed from the containers, further identified, inspected, and moved to the specific location at the site where they are
installed. If installation is delayed for some reason, the materials should remain in
3-4
