Conservation of water

• We know the importance of water for existence of life on Earth.
• We also know that only a small percentage of water in the planet is usable. That makes it very precious.
• We should not waste water and this can begin at home, both indoors and outdoors.
• Water saving can be done from an individual level to a national level.
• One method of conserving water is by constructing a dam.

Dam:

• A dam is a structure built to hold backwater in order to prevent flooding, and to provide water for irrigation and storage.        

Dam

• Built on rivers, a dam has high walls and has many openings or gates to both let in and hold back water.
• During the rains when the rivers fill up, water enters the dam.
• Again, when water is needed later, the gates are opened to let out water.
