WISY AG has its company headquarters in Hitzkirchen, a small town surrounded by meadows and forest within the boundaries of the Vogelsberg nature recreation area in Hesse, Germany.
The company began producing rainwater filters in 1989. Thanks to its unique filtering concept and its success in systematically developing its product range, WISY AG quickly grew to become the leading manufacturer of high quality rainwater harvesting systems. WISY is now securely established as a global supplier of rain harvesting products with partners in over 40 countries. In addition to manufacturing high-quality products, the company has always understood the importance of product-specific training. In an in-house training centre, more than 10,000 installers and distributors have since received instruction in the fundamental principles of rainwater harvesting.
WISY is a founder member of the German Association for Rainwater Harvesting and also participated in the DIN committees which drew up the currently applicable standards. The durability and reliability of its products are a distinctive feature of the WISY brand.
WISY´s products have consequently found use in many thousands of projects around the world, especially where professional rainwater harvesting solutions are required. It is in public buildings in particular - scholls, hospitals, and fire stations, for example - that WISY products can guarantee a reliable rainwater supply.
