OPERATOR AND UNIT MAINTENANCE MANUAL
(INCLUDING REPAIR PARTS AND SPECIAL TOOLS LIST)
COLLAPSIBLE FABRIC TANKS, FUEL STORAGE, 3,000,
10,000, 20,000, AND 50,000 GALLON
OPERATION UNDER USUAL CONDITIONS
ASSEMBLY AND PREPARATION FOR USE
Construction of Berm
WARNING
Make certain that the berm ball valve is closed and locked after installing and
draining the berm. In the event of tank rupture, an open berm ball valve would
permit fuel to drain from the berm. Undetected fuel leakage can result in an
explosion and cause death, severe personal injury, and damage to equipment.
CAUTION
Damage to tank may occur if chosen site is not free of sharp objects (rocks,
sticks, glass, etc.), and center of leveled area should not exceed 9.0-inches
(22.86-centimeters) below ground level. Retain a slight incline for draining
surface water. Safety berms must have capacities of not less than one and one
half times that of the tank capacities. Failure to construct a secure safety berm
may result in catastrophic damage.
NOTE
A minimum of 10.0-foot (3.048-meter) working clearance is necessary between the side
of the tank and the berm on all four sides. When a single berm is used to contain more
than one tank, maintain a 10.0-foot (3.048-meter) space between tanks. The
installation site should have less than a 3.0% grade (3-inch (7.62-cm) rise in a 100-foot
(30.48-m) run) in order to prevent creeping of the tank. The site must not be subject to
flooding or high water.
NOTE
If possible, provide a 4.0-inch (10.16-centimeter) thick sand bottom for all collapsible
fuel storage tanks. To provide a berm drain for all collapsible fuel storage tanks, place
a 2.0-inch (5.08-centimeter) pipe with a ball valve through the bottom of the discharge
end of the berm in order to provide a means of draining accumulated water. Position
the drain assembly at the lowest point of the slope to aid in draining water or sludge.
The ball valve should be normally closed, and opened only to drain water from the
bermed area.
3,000-Gallon (11,360-Liter) Tank
NOTE
The following instructions are for a 14.0-foot by 14.0-foot (4.267-meter by 4.267-meter)
tank in flat (empty) dimensions.
1. Clear and level an area so there is at least a 13-foot (3.962-meter) perimeter around the empty flat
tank.
2. Slope all four sides of leveled area in toward the center. The center should be no more than 3.0
inches (7.62 centimeters) below ground level, equal to an approximate slope of 1.0 degree.
