terrain, and site preparation.
When considering cover and concealment,
select a site that is in the woods or in a tree line where natural shadows
disguise the shapes of the equipment. Always use camouflage nets whenever
possible. When laying out the operations, make use of the natural terrain
contours and vegetation to break up straight lines.
e. Choose a site for the distribution and receiving points that is next
to a road in the water supply point.
Loading or unloading trucks and
distribution to consumers can be done without leaving the road nets in the
supply point. Ensure there is only one-way traffic.
f. Consider the distance between pieces of equipment when selecting the
location for the PWS/DS.
The distance can vary with the terrain, natural
cover, concealment, hose availability, and the road nets.
Select level
terrain for the PWS/DS. Look for a site without slopes. A large slope will
cause filled tanks to roll. Put the pumps and the distribution equipment on
level ground.
Try to place the distribution pumps at a slightly lower
elevation than the collapsible tanks to ensure suction at the pump.
g. Position the collapsible tanks, the pumps, the hypochlorinator, and
the distribution equipment in the PWS/DS. The entire area of the tank farm
must be cleared of all sharp objects (such as stones or sticks) that might
puncture the tanks. The tank sites should slope gently toward the discharge
manifold end to help drain the tanks.
For more complete emptying of the
tanks, a sump approximately 36 by 36 by 2 inches should be dug under the
drain fitting to provide a low area for the water to collect.
If it is
determined that a dike is required, it should have an internal volume
equivalent to or greater than the volume of the tank. If an engineer unit
is available to assist in site preparation, give it this information.
2. Flow Plan.
After selecting the specific site for the actual parts of
the water supply point, develop a flow plan. The flow plan will assist in
determining whether personnel are handling the water and containers too
much. The flow plan identifies steps that can be eliminated, combined, or
changed to make the operations more efficient.
It can also indicate
unnecessary delays in handling and transporting of the water.
When
developing the plan, consider the location of the storage and distribution
equipment and consider the flow of traffic through the supply point. Only
one-way traffic should be permitted in the supply point. Study the area and
make up a flow plan before the supply point moves to the new location.
