routine tests of source and product water to adjust treatment processes and ensure potability. They also
set up and operate PWS/DS and lay, operate, and retrieve TWDS.
c. US Army Ordnance School. The Quartermaster and Chemical, Equipment Repairer (MOS
63J) performs unit and intermediate DS and GS support level maintenance of water purification, storage,
and distribution equipment.
d. US Army Academy of Health Sciences and the US Army's Command Surgeon General. The
Academy of Health Sciences and the Command Surgeon General monitor preventive medicine water
inspection programs, define degree of water treatment required, establish command disinfectant residual
policy, and approve treated water for Consumption. The Preventive Medicine Specialist (91S) assists
water purification units in water source reconnaissance, approves water sources, inspects water points,
inspects potable water containers, and analyzes treated water to ensure water quality standards are met.
When appropriate medical authorities are not available in the TO for potability certification of water
supplies, the senior 77W will certify potability. This is to allow water to be issued to supported units as
an interim action pending the arrival of qualified medical personnel. This authority is conditional on the
drinking water having been treated by reverse osmosis water purification equipment and the chlorine
residual maintained at 2 PPM at the production site.
e. Commanders. The commanders provide soldiers with safe drinking water and ensure they
understand the dangers of drinking unapproved water. They also provide higher headquarters with
water requirement estimates based upon climate-related consumption factors. Commanders ensure
soldiers drink adequate amounts of potable water for the climate region and type of operation. They
safeguard unit water supplies with good sanitation habits.
5. Operational Concept. The force structure for water support in a TO divides water support into DS
and GS levels. DS capabilities are sufficient to meet requirements in temperate, tropical, and arctic
regions. However, in the arid regions where sufficient water sources are not available, GS water
systems are set up. DS is provided to both nondivisional and divisional units. Effective future water
requirements will require redesign of EAD water assets. Modularly designed water support units which
incorporate both DS/GS capabilities that could deploy as needed while still maintaining a DS role in a
nonarid environment would eliminate redundant productions capability and increase mobility.
Nondivisional water support is provided on an area basis by corps and EAC Quartermaster supply
companies. The organic water supply section of the company provides water purification and storage at
water supply points using approved sources. Most units served by the supply companies will obtain
resupply through supply point distribution, traveling to the water storage site or water point to fill
organic water storage equipment. Some major users such as hospitals require unit distribution. This
will be done using tankers currently in the Army inventory and future bulk transport capable equipment.
Divisional water support is provided by divisional direct support elements, augmented by GS
augmentation teams in arid environments. Water purification points are set up at water sources in each
BSA and at up to two points in the DSA. In the future, combat brigades in all divisions need to be able
to provide unit distribution of water to the combat units and the combat support units which maneuver
with them. Water will be delivered from water points to company trains, LOGPACs,
