2-14. This section has instructions for operation of the WDS20K, WDS40K, WDS300K, WDS800K, and
WDS1,000K water distribution systems in arctic conditions, extreme heat, and dusty or sandy areas.
2-14.1 350 GPM Pump Assembly. Refer to TM 5-4320-226-14 for operation under arctic conditions, extreme
heat and dusty or sandy areas.
2-14.2 125 GPM Pump and Engine. Refer to TM 5-4320-208-12&P and TM 5-2805-257-14 for operation of the
125 GPM and engine under arctic conditions, extreme heat, and dusty or sandy areas.
2-14.3 Water Hoses 20,000 and 50,000 Gallon Water Storage Tanks.
a. Arctic Operation. Store water hoses and tanks in a heated area to avoid freezing. Remove snow, sleet or
ice from tanks before installing couplers. Be careful to prevent cracking tanks if frozen. Wear arctic mittens when
handling hardware associated with the hoses and tanks.
b. Operation in Extreme Heat. Protect water hoses and tanks from extreme heat by covering with tarpaulin,
burlap, or shade with trees. Ventilate area around the tanks to allow cooling air circulation.
c. Operation in Dusty or Sandy Areas. Keep dust caps in place on water hoses and tanks until ready to con-
nect fittings. Inspect couplings for presence of dirt before connecting hose fittings to tanks.
2-14.4 HYPOCHLORINATION UNIT.
a. Arctic Operation.
To prevent hands from freezing to the metal, wear arctic mittens when handling hard-
ware associated with the hoses and tanks.
Fumes from the Hypochlorination Unit can cause sickness or even death. Be sure that
the unit is in a well ventilated area.
To prevent damaging the Hypochlorination Unit due to freezing, heat with forced air.
b. Operation in Extreme Heat.
Fumes from the Hypochlorination Unit can cause sickness or even death. These fumes
are increased when hypochlorite solution is subject to extreme heat. Be sure that the
unit is in a well ventilated area.
c. Operation in Dusty or Sandy Areas. Keep Hypochlorination Unit reservoir covered to prevent water system
from becoming contaminated by blowing dust or sand, Do not remove caps and plugs from fittings until hose
connections are ready to be made.
