maneuver units have enough stocks to meet needs. It diverts stocks as necessary. The branch directs water
shipments according to plans for specific operations. It consolidates division water needs and sends them to
COSCOM MMCs. It coordinates with the division engineer staff on needs for help in preparation, site
access, or other construction support requirements for water sites. It coordinates with the corps engineer
staff on division needs for water source detection support and water well drilling. It provides data and other
help to the division G4 for planning requirements and water support operations. It provides staff expertise on
water quality control and treatment standards and coordinates with the division surgeon's office on water
Receiving from Forward and Main Water Points Total Daily Water Requirements.
Division units submit water supply requirements, usually consolidated at battalion level, to the supporting
water point. The water section uses standard computations data to determine the total daily water needs for
supported units. The supporting water point sends the total daily needs to the DMMC.
A number of computations must be made to determine supply and storage requirements for water.
Personnel strength data are used by the DMMC managers to compute water requirements. The MTOE and
TDA provide authorized strengths for planning before hostilities begin. Data from the SIDPERS and
subsisted strength reports may be used to modify requirements after units are established in the theater.
To compute the total daily water requirement of the force, multiply the strength (authorized, actual, or
subsisted) by the proper consumption factor (refer to Table 1-3). The total, expressed as gallons per day,
includes 10 percent for waste due to spills and evaporation.

Determining If Divisional Distribution/Storage Capability Is Less Than, Equal to, or
Greater Than Divisional Requirements. The DMMC water section receives total daily
requirements from the forward and main water points. It checks purification and storage capabilities of each
water point and diverts stock if necessary. It combines and submits the total daily water requirements to the
COSCOM MMC. Daily operations of COSCOM MMC personnel include directing storage and distribution of
