<ul><li><p>Water is life </p><p>Virtually everything we do or use each day involves water. Yet, we do not give it the importance that is due to it. India will soon be a water-stressed country and we all need to work towards our water security. Simple actions can be adopted to reduce the wastage of water and use it wisely. 1</p></li><li><p>Water audit for a school2</p></li><li><p>INTRODUCTIONWhat is a Water Audit?
