Water is essential for life. Humans, animals and plants all need water to live and to grow. But in
many parts of the world humans have no access to the clean drinking. Water is polluted with germs, worms, or toxic chemicals and this can lead to many illnesses [1]. In developing countries, about 80% of urban wastewater is used for irrigation paying to 70-80% food security and livelihood of urban and peri-urban communities [2]. It has been estimated that 64% of total wastewater of Pakistan is disposed of either into river or into Arabian Sea. Similarity, 400,000 m3/day are moreover added to canal [3].
