water and reviewing and analyzing demands. They evaluate and balance work loads and resources of water
supply units in the combat zone.
Temperate, tropical, and arctic regions usually do not require large amounts of potable water to be
stored. Their nonpotable water requirements can be met by raw water sources, and their potable water
requirements can be met by the water purification section's organic storage tanks. In arid regions, large
quantities of potable water must be stored because such water is used for both potable and nonpotable
requirements. Brigades and divisions deployed in arid regions will have additional storage teams assigned.
Raw water storage may be needed to provide source water for purification equipment. To compute the total
storage requirement, determine the location and daily requirement on the battlefield (brigade, division, corps,
or EAC). Double the daily requirement at corps and EAC to provide an additional day of supply at these
levels. Then, compute the number of water supply companies needed to store the total requirement by
dividing it by 1.6 million (the storage capacity, in gallons, of one water supply company). Allocate the
companies in the corps and COMMZ to store that portion of the total requirement found in each area.
Cross-leveling Main and Forward Water Distribution/Storage Capability to
Requirements Where Possible. Ensuring Each Echelon Has Necessary Storage and
Distribution Capability to Meet Mission Requirements, but no More. Water storage policy
depends on the environmental region. Where water sources can support water purification operations,
supported units need only maintain water in organic water containers and optional equipment from the CTAs.
For a normal unit, this means maintaining enough water to get through today's operations. Under these
conditions, units must resupply water daily. Tactical units and their applicable divisional supply and
nondivisional water supply units will not normally be augmented with additional water purification, storage, or
distribution equipment. Readily available water sources (wells, lakes, and rivers) will be considered as
sources of raw water that can be purified on demand.
In arid regions, water sources are nonexistent or extremely limited. Commanders will make use of all
organic water storage and distribution equipment and must draw and use all CTA water equipment. In arid
regions, combat brigades, divisions, and hospitals will be assigned additional water storage and distribution
equipment. This will ensure that one DOS is maintained in each echelon level. GS storage and distribution
systems are provided to maintain the required supply levels.
Take the figures for total daily demand of forwards and main and determine if the elements must be
augmented with additional storage.
Submitting to COSCOM MMC Distribution/Storage Requirement Shortfalls. Getting
water to the soldier in the individual fighting position is the critical link in water distribution operations. If this
link fails, it does not matter what the condition of the purification, storage, and distribution assets are at
brigade, division, corps, or echelons above corps. Each unit commander must use planning factors to
determine what the daily requirements are. This daily requirement must then be compared with the
capability of the unit's organic equipment available for water distribution operations. If a significant shortage
exists or a commander desires additional flexibility, he must program resources and procure the necessary
items from the CTA. Once storage and distribution requirements have been identified, submit request for
shortages.
To fulfill its mission, the COSCOM MMC performs the following:
Directs storage and distribution of water supplies.
Provides inventory management of GS water supplies stocked with the corps.
Receives and processes requirements for water from supported activities.
Passes requirements to TAMMC or directs issue from available stocks.
Collects, sorts, and analyzes water supply and maintenance data.
Sends data to the MCC or forecasts needs for water movement in the corps for the MCC's use in
creating the corps movement plan.
Personnel in the CMMC handle water for the corps. They manage:
Day-to day water support needs.
Production, storage, and distribution of water.
Reports and information needed for routine activity.
