Kilian Water

Kilian Water would like to be your partner for natural wastewater treatment in suburbs, small villages and rural areas.

Kilian Water makes tailor made designs and builds constructed wetlands and willow evaporation systems in collaboration with local contractors.

We are providing expert guidance throughout all phases of the process from the recommended type of wetland, construction and maintenance to sampling and testing. If required we can also assist in the preparation and application process (forms and drawings for municipality, etc.).

Kilian Water collaborates with Aarhus University, Danish Technological Institute, the EU as well as other partners regarding research and development of sustainable wastewater treatment in both Denmark and abroad.
