ABSTRACT
Water is the most plentiful and vital liquid on earth. No life, as we know it, could exist without water as it provides the essential medium in which all things grow and multiply.
In recent years the steady growth in the numbers of agricultural businesses, including viticulture, aquaculture, irrigating crops and grazing animals, has increased the demand for water supplies. No longer can the small, muddy small dam or the small bore with windmill provide adequate supplies of clean water for these uses.
