Title: Rainwater harvesting at a family home
Drinking water can be conserved by utilizing rainwater for toilets, watering lawns and gardens, and cleaning work. A rainwater harvesting system enables a family of five in Lambach, Upper Austria, to fulfill this dream. Since February 2009 the system has been operational in the low-energy home. An underground storage tank enables collection of rainwater for utilization on demand; even in periods of low precipitation, complete watering of the garden is possible. Because rainwater is softer than city water, it is ideal for washing clothes and even as coolant. Another benefit is the money saved on drinking water and sewage.
