This unit describes the skills required to locate, treat (for human consumption) and manage water in a survival situation. This unit also includes extracting water directly through evaporation, transpiration and desalination; filtering techniques; and treating foul water to render it potable. Of equal importance to optimising the input of water, is minimising the expenditure of water. Individuals will need to protect and ration their water assets and to implement measures to minimise water loss to increase their chances of survival.This unit was developed for Defence personnel but may be relevant to others.The skills and knowledge described in this unit must be applied within the legislative, regulatory and policy environment in which they are carried out. Organisational policies and procedures must be consulted and adhered to.Those undertaking this unit would act autonomously, while performing concrete tasks, in a broad range of contexts which may be highly unpredictable.No licensing, legislative or certification requirements apply to unit at the time of publication.
