Water is our most precious resource and is vital for all existence of life. It is everywhere,including our lakes, ponds, streams, wells and reservoirs, and unfortunately due to pollution, has taken a negative effect on the quality of water. Major water pollution comes from industrial waste water,chemicals, detergents, pesticides and weed killer, municipal sewage, acid rain, residue from metals,bacteria and viruses, and even excessive, artificially enriched plant growth.

A recent estimate states that over half of available freshwater resources are at present being used to meet human needs, and could increase to 70% in 30 years. The tests for engineers of the future will be to create more refined treatment systems that can more thoroughly treat water pollution at its original sources, while continuing to cleanse polluted water site and facilities in order to deliver freshwater resources to rising populations.
