Ways to use rainwater
Saving on drinking water
Drinking water is scarce and expensive. In Germany the average person uses about 130 litres of drinking water per day. Half could easily be replaced by rainwater – in a four-member household that is about 90,000 litres a year. Those who use rainwater save drinking water, protect the environment, reduce the load on the public sewer system and thus also on their own pockets. This is because many city and local authorities promote the use of rainwater through grants or have a split wastewater charge.
