Welcome to the World of Drinking Water!



Since thirty years WEIL Wasseraufbereitung GmbH has dedicated itself to return to the water what threatens to get lost: its purity. The part of residential water is done now by our sister company ROWA4you.


Nothing exists without water. We humans consist of approximately two thirds of water - exactly like most of the plants and animals and the earth altogether! Water – it still fascinates us every day – is a material with no replacement neither in nature nor in the laboratory. Our goal and versatile task is to take the responsibility for this precious material.

The World of Better Water


Our Company conceives water treatment units, special purifying methods and high-quality filtration technology. We decided to use our know-how also for the final consumer and have therefore developed the trademark ROWA.

To be able to enjoy good water in a quality, as if it would come directly from the source, keeps finding more and more fans. Enjoying pure water does not only keep you fit, but it also makes beautiful. Besides that pure water consumption is also the healthiest treat that ever exists.


To your health!
