1.1 Background
of Study
In
terms of Sustainability and environment, the natural elements play important
roles for ecological preservation. Water is the most abundant environmental
resource on earth but its accessibility is based on quality and quantity, as
well as space and time. It may be available in various forms and quantity but
its use for various purposes is the subject of quality. About 70% of the human
body and about 60-70% of plant cells is made up of water (Smith and Edger, 2006).
It is one of the determinants of human settlement, existence and activities on
the earth. Its quantity is fixed but dynamic in formation and storage. Of all
the environmental concerns that developing countries face, the lack of
adequate, good quality water remains the most serious (Markandya, 2004). Once
contaminated, groundwater may forever remain polluted without remedy or
treatment. Water is one of the determinants of human earth system. Diseases may
spring up through water pollution, especially groundwater contamination, and
rapidly spread beyond human expectation because of its flow mechanism (Afolayan
et al., 2012). One of the major factors that make the earth habitable for
humans is the presence of water. Forming the major component of plant and animal
cells, it is the basis of life and therefore the development of water resources
is an important component in the integrated development of any area.
Water is critical to our daily lives and is an extraordinary compound in nature. It covers 71% of Earth (USGS, 2014). Water is the most important resource of a country, and of the entire society, since no life is possible without water. It has this unique position among other natural resources, because a country can survive in the absence of any other resource,except water (Garg, 2009). According to the National Water Policy (2002), in the planning and operation of systems, water allocation priorities should be broadly as follows: drinking, irrigation, hydropower, ecology, agro-industries and non-agricultural industries, navigation and other uses.
