Water scarcity has become a serious concern for human habitat. Many of the metropolises are facing acute water shortage. Saving this natural resource has thus become the need of hour. Here, most of the big apartments use STP(sewage treatment plant) to reuse the waste water. Personally, we could significantly add to this cause. Our water filter drain out equal amount of water of what it purifies. I store this water to use in household activities like mopping, cleaning, washing etc. Besides, the water that is used to wash vegetables, I use them for gardening. Do you have water scarcity in your cities? How do you save water?
