Rainwater Harvesting System

EcoTec offers Rainwater Harvesting System. The company Otto GRAF GmbH from Teningen, founded more than 50 years ago, offers rainwater harvesting systems for individual as well as industrial use, in many different sizes and designs. They are the market leader for plastic rainwater collection tanks in Germany and Europe. As a result of increased water consumption in the last several years, water is becoming increasingly scarce. Even more significant, however, than the problem of quantity is the water quality. Due to more and more extensive contamination with harmful substances, phosphates, pesticides and other chemical substances, water treatment is becoming not merely more difficult, but also more expensive. Statistics document that only one person uses, on average, 140 litres of valuable drinking water each day. However, for approximately 50% of uses, drinking-water quality is not imperative, e.g. for flushing the toilet, operating the washing machine, irrigating gardens and parks, operating a car wash, etc. Especially for these purposes, the use of rainwater enables savings of approx. 70 litres per person and per day.
Advantage:

• It is free of charge
• It must not be pre-treated
• It offers protection from calcification of the washing machine
• It is an optimum medium for plants to absorb minerals, etc.
