Earth has 1/3 percent water. But only around 1 percent water is pure and can be used for drinking. Hence we need to save water.There are many ways to save water. Some of them are- 

1. Use bucket instead of showers 
2. Close taps properly after use 
3. Fix leaking taps 
4. Do not put garbage in rivers,lakes,oceans etc.

These can save water from being wasted or polluted.
