4. Movement. The supply point equipment will arrive by means of a convoy.
Give the drivers the exact location of the site.
Someone must be at the
location prior to the convoy getting there. The area should be well suited
for off-loading of the equipment. If the site has already been prepared by
the engineers, begin off-loading and laying out operations. If the site has
not been prepared by the engineers, it is the water unit's responsibility to
do so. The first and major concern is to receive and issue potable water as
soon as possible. For this reason, off-load and lay out the storage tanks
first, then off-load and lay out the distribution operations.
5. Site Setup.
Lay out the PWS/DS to take advantage of the terrain,
natural cover, concealment, available hose, and road nets. The best way to
lay out the PWS/DS is to put the collapsible tanks in their prepared sites
first. Then put the pumps and hypochlorination unit in place, and lay out
all the fitting assemblies and hoses. Make the connections, and attach the
water distribution nozzles.
a. Preparing the collapsible tanks is relatively simple.
tanks in the prepared sites so that when unfolded, they are in position. Be
careful not to step on the tanks when unfolding them. Then inspect the tank
fabric for cuts, sags, or other possible damage. Also, ensure that the tank
filler and vent assemblies are in good working order.
b. After putting the 125-GPM and 350-GPM pumping assemblies in place,
lower the retractable support and check the wheels of the 350-GPM pump.
c. After placing the hypochlorination unit in place, put shims under
the skids to help keep the unit level. Then, raise the cover of the unit to
ensure it is serviceable.
d. There are four types of stations provided in the system: 4-inch
loading stations, 2-inch loading stations, dispensing stations, and bag
If you connect the 350-GPM pump as the discharge pump,
water can be pumped through the 4-inch hose section to and from SMFTs.
There are four to eight 2-inch loading stations.
The 2-inch loading
stations use 20-foot, 2-inch hoses. Quick-acting valves are used to control
water flow through these hoses. There are four dispensing stations. These
stations deliver water through hand-held nozzles.
The third station, the
bag filler station, delivers water through a 1 1/2-inch hose to a nozzle kit
for filling 5-gallon plastic bags. There are three bag filler stations in
e. Set up checkpoints at the entrance and the exit of the supply point.
Give personnel coming into the area a safety
