Rainwater harvesting

Water - the source of life energy

The properties of the water cannot be compared with anything. It is the basis of life for plants, animals and people. The use of rainwater allows us to use precious drinking water responsibly and sparingly. An effective system consists of an earth cistern with feed from the rain gutter and a domestic waterworks with automatic drinking water replenishment for times of low rainfall. The free rainwater can be used for watering the garden, for flushing toilets and for the washing machine. The savings potential is impressive:
The average annual precipitation is approx. 800 to 1000l / m². A prefabricated house with a floor area of ​​100 m² could collect approx. 80,000 liters of rainwater per year. If one takes as a basis that a 4-person household consumes approx. 330 liters of water per day, this results in approx. 120,000 liters of drinking water per year. More than 12% (approx. 14,000 liters) of this precious drinking water is used for flushing toilets, washing machines and watering the garden.
In view of the rising prices for drinking water and wastewater in connection with an increased sensitivity for the precious raw material drinking water, the investment in a rainwater harvesting system is a worthwhile investment in the future.
