    WISA is 150 years old and we are proud of it! In 1865 we started in Arnhem with a metalware factory, founded by WJ Stokvis. Today we are active worldwide in the field of sanitary flushing technology. To mark our 150 years in the industry, we have used the available material to chart the DNA of WISA. We hope that you enjoy reading about our history.
