There are many ways of saving rain water,one way is by collecting rainwater.Rain water is what plants love,because it's free of chlorine,potassium,and other chemicals.
Besides using rainwater for flushing toilet you can also use it for watering your indoor and outdoor plants, grass, washing your car, boat, jet ski, bicycle, cleaning the aluminum sidings of your house, or topping off your pool.
Other advantages is that it directs moisture away from your home's foundation.
The beauty of rainwater is that its free of chemicals, chlorine, lime or calcium. A rain barrel will save most homeowners about 1,300 gallons of water during the peak summer months.

Think about it for a second, only 1% of water is potable, the rest of the 97% is composed of the ocean and 2% is found at both extremities of the ice poles.
