the clamp through the hole or tear and rotate it until it is centered and
its length runs with the tear. Pull the bottom plate up against the fabric
of the tank and slide the top plate down the cord onto the threaded stud on
the bottom plate.
With both plates now aligned, tighten the wingnut to
clamp the tank wall between the two plates. Tighten just enough to stop the
leak. If pliers are used, do not overtighten, as the stud threads may be
stripped or damage can occur to the fabric of the tank.
c. Observe the following general instructions when patching. Patching
of the tank fabric must not be done if the ambient temperature is less than
60 degrees Fahrenheit. Patching must be done in an area which will remain
dry, and at a minimum ambient temperature of 60 degrees Fahrenheit for 48
hours. Make sure the tank fabric is completely dry before beginning repair.
Tank fabric which holds water must have two patches: one on the inside and
one on the outside. The inside patch (water side) must be applied first.
Tank fabric which does not hold water needs only one, outside, patch. Do
not mix adhesive before ready to begin repair. Maximum shelf life of mixed
adhesive is eight hours. If patch must be applied in an area where it will
come into contact with a previously installed patch, use emery cloth to
smooth down the edges of the existing patch.
There must be a smooth
transition to the tank fabric. For more specific repair procedures, refer
to TM 5-5430-225-12.
PART B - SUPERVISE GS STORAGE OPERATIONS
In arid areas where organic DS water systems are not capable of providing
water supply due to the lack of local water sources, GS units provide this
capability.
Purified water is introduced into the water storage and
distribution system from purification points located onshore and offshore.
This water is stored in PWS/DSs.
From there it is distributed to other
PWS/DSs within the COMMZ and forward into the corps area by the TWDS. These
PWS/DSs can vary in size from 800,000 to 1.6 million gallons, consisting of
50,000-gallon collapsible fabric tanks. DS units, augmented with 40,000-and
300,000-gallon PWS/DSs, receive water from SMFTs that move water supplies
from the GS water units in the corps/COMMZ into the division/brigade areas.
The 300,000-gallon system is equipped with sixteen 20,000-gallon collapsible
fabric tanks configured either as one 300,000-gallon tank farm or as two
160,000-gallon tank farms.
The 40,000-gallon system is equipped with two
20,000-gallon tanks.
Make sure all soldiers under your supervision know and understand their
environmental stewardship responsibilities.
