Why Rain Water Harvesting? The demand for water is growing at a rapid pace in most of the cities of our earth as the world is rapidly urbanizing. Every urban citizen requires almost double or even more than the amount of water that an average rural citizen requires.

Moreover, the urban population in most of the cities in our world has grown almost many multiple times in the last few decades. Not so long ago, most of our cities were self-sufficient in meeting their water needs from the extensive urban water bodies which had sufficient water to take care of its citizens’ water needs. Today these water bodies have completely disappeared. Municipalities have been stretched to their limits to find water for the growing urban populations. The groundwater is being extracted by the government as well as the private parties at an alarming dangerous and disastrous rate, without a single thought of replenishment ever.
