It covers water support planning, transportation, storage, distribution, purification, consumption, and water reuse. It requires water-supply discipline, protected water inventories, tactical water concepts in field-training exercises, and planning for environmental conditions.
Tactical water resources management includes policy and planning, transportation, storage and distribution, and computation and submission of requirements. (paragraph 1-1)
Commanders will establish and enforce procedures for water-supply discipline, including water-conservation initiatives. (paragraph 2-14)
Commanders will enforce adequate water consumption for the various environmental conditions and activity levels encountered, in accordance with TB MED 507, to prevent heat casualties. (paragraph 2-14)
Since the capability of Army units and other services to fulfill their own water requirements may be difficult to predict, logistics planners must provide a force structure adequate to purify, store, and distribute the daily requirement for the force. (paragraph 2-16)
Planners should estimate time-phased water requirements using consumption planning factors found in the Army Water Planning Guide to account for each type of environment. (paragraph 2-16)
