The conventional approach to water management has
proved inadequate for the long-term sustainability of
the world s water resources. In response to
inadequacies in conventional water management and a
need for sustaining ecosystems, Sustainable Water
Management has become the desired paradigm and is
comprised of the following key considerations: Water
quality and quantity should not be degraded or
reduced over the long term; Present and future basic
human water needs are met; and Ecosystem integrity
and biodiversity are maintained. The Water Resource
Sustainability Model is a pragmatic tool developed to
assess the sustainability of a watershed s water
resources. It was created based on the key principles
of sustainable water management with the exception of
water quality which remained beyond the scope of this
study. The model provides a sensible way of testing
whether particular water consumption patterns can be
sustainable in the long term. The Water Resource
Sustainability Model provides helpful insights to
sustain water resources as the computer model
process is to the mind what the telescope and the
microscope are to the eye (Heinz Pagels, 1988) .
