Yes Water is very precious. There will be a day when everyone will be fighting just for a drop of pure water. Water is getting polluted from industries, domestic purpose, drainages etc.
I feel the major portion of pollution happens from the usage of Soaps and Detergents. I feel an environment friendly soaps/shampoo/detergent should be the order of the day. If some alternative to soaps/detergent is made which wont have any affect on water, then our world will be better place to live.
