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.
