The constructed wetland filter is a powerful solution for the future, an environmental friendly, sustainable and multi-applicable way to purify all kinds of waste water in a natural way.

The waste water is pumped into the top of the sand filter, from where it percolates through the root zone of the reeds, where it gets oxydized and the nutrients broken down into smaller mostly harmless molecules. At the bottom of the filter, the water enters the drain pipes and is being conveyed into an infiltration bed.  Although the reeds are mown in late fall, the root zone remains active in winter, so the system remains active under cold circumstances.
