Abstract
One requirement of sustainable irrigation is a guaranteed source of water at
adequate levels. It is also obvious that the cost of the irrigation water delivered to
the user must allow the user to profit from its use. The costs of irrigation falls
typically in three categories: 1. Cost of the water used; 2. Energy cost to purify
and transport the water; and 3. Initial costs of the infrastructure and its
maintenance. This paper addresses all of these requirements for sustainable
irrigation. It is proposed that the ocean is the ultimate source of
sustainable water. Further the required purification of the water is to be
accomplished by a novel reverse osmosis system which minimizes the energy
costs. Finally, a solar collection system is incorporated in the proposed system to
minimize the impact of global warming due to use of fossil fuels. The proposed
system has particular application to desert areas near oceans such as North Africa
and Australia. This paper includes the development of a model for performance
and cost of the system and shows the circumstances for which the proposed
system is viable.
