We have several ways of conserving water, the only thing is that first is all about to set your mentality to really conserve water at every stage of work you do. From morning brushes till night sleeping, you would waste a lot of water. Just try to go with your works for a day without water, then you will surely come to know the importance of it and will start conserving it, I say it is just impossible even to imagine to live without water for a day. This is especially to remind those people who lavishly spill water just for their luxury.
