(3) General support units are deployed to augment DSUs in an arid environment. These
GSUs will store and issue potable water only. Because it will be the only available water, potable water
will be issued to satisfy requirements traditionally met by nonpotable water.
(a) The HHD, Theater Army Quartermaster Petroleum Group (TOE 10-602L)
provides command and control of all GS water assets. One QM Group commands from two to five
water supply battalions.
(b) The HHD, Water Supply Battalion (TOE 10-466L) provides command and
control for up to 5 assigned or attached GS water companies or 5 detachments or 10 teams. This unit is
normally located in the theater army area.
(c) The Water Supply Company (TOE 10-468L) is assigned to the force to operate
bulk PWS/DS for GS water operations. The water supply company has as initial equipment two
800,000 gallon PWS/DS and two TWDS. The company can be augmented with up to six more TWDS,
giving a total of 80 miles of hoseline.
(d) The mission of the TWDS team (TOE 10-570LB) is to lay, operate, and retrieve
the distribution system. Each water supply company will have two TWDS teams and can be augmented
with six more.
(e) Water purification teams and detachments augment DS water systems and
produce all GS potable water within the theater. The Water Purification Team (TOE 10-570LC)
operates the tactical 3000-GPH ROWPU (four per team). The team is normally deployed in the Corps
area to augment Corps-level DS purification units, but may be assigned to exploit water sources in
division areas. The Water Purification Detachment (TOE 10-469L) normally operates the 3,000-GPH
ROWPU (10 per detachment). The detachment can operate on any large water source and is generally
near base terminals.
(f) The TMT Company (TOEs 55-023J411 and 55-018J411) provides distribution
capability. The SMFT, a collapsible tank, is the primary means of distribution pending the emplacement
of hose lines and storage systems. The TMT company (TOE 55-023J411) uses the M871, 22-ton
semitrailer to haul potable water in the 3,000-gallon SMFT to division and brigade suppo areas from the
PWS/DS in the Corps support area. The 5,000-gallon SMFT is normally issued only in arid
environments. The TMT company (TOE 55-018J411) uses the M872, 34-ton semitrailer to line-haul
potable water in the 4,570-gallon SMFT to units in the corps and EAC.
6. Water Force Structure Planning. The proper force structuring of water support and the timed-
phased deployment of units in that structure is an iterative process. It is done by organizational
integrators who consider the operational scenario, strategic lift availability, and pre-positioned supplies
a. The process normally begins with the identification of the force size and planned troop
deployment rate. Time-phased water requirements are then estimated using consumption
