Rainwater harvesting simply means the collection of rainwater for re-use, instead of allowing it to run off into the ground. The rain water collected has a myriad of uses; gardening, irrigation, water features, livestock, washing, bathing and heating.
With minimal treatment, rainwater can also be used as drinking water, and is just as safe as the water that comes out of your tap. Just as solar power provides free energy, rainwater harvesting provides free water. Not only will it reduce your utility bill, it increases the sustainability of our reservoir and groundwater supplies. Rainwater harvesting means that you can bypass water restrictions to some extent, using your own supply instead of a limited supply of main water.
