Rainwater harvesting

Rainwater harvesting
Australia is the driest continent on earth and in most rural communities rainwater is the only supply of water for human consumption. Australians have used rainwater for many years as their source of water for all requirements - drinking, cooking, bathing, laundry, toilet flushing through to watering the garden. This is also true for many other communities around the world.
