We know that the amount of freshwater is declining day by day. The demand of water has increased due to steep rise in the population. Due to this, extreme scarcity of water occurs and many people in our country do not even get sufficient drinking water. In villages, sometimes villagers have to collect water from long distances to fulfill their needs.
They spend several hours in a day, just to collect a small quantity of water. Many people draw out underground water by digging bore wells. Due to continuous use, underground water is also not easily available. One has to dig deep bore wells to reach the water table. This is because the groundwater is not sufficiently replenished with rainwater because of the excessive construction of roads, buildings and pavements.
