Three examples of water wastage and solutions: 1) Leaving the tap running while washing dishes wastes water - we can fill a basin with water for washing instead. 2) Using a hose to wash cars wastes large amounts of water - we can use a bucket and cloth to save water. 3) Flushing the toilet unnecessarily uses several litres of water - we can use the half-flush option or place a filled bottle in the tank to reduce water usage.
