Our siphonic roof drainage system is the cost-effective and reliable solution that removes substantial water volumes with fewer drains

The BLÜCHER® EuroPipe stainless steel drainage pipework system is an integrated part of the siphonic roof drainage system.


Thanks to the stability of the stainless steel piping, additional support rails and brackets are not necessary. The minimal number of components not only makes the installation of the system the easiest and fastest in the market, but it also makes it the siphonic drainage system with lowest total weight.

Green roof drainage is meant to drain the layer of soil on the roof

Green roofs enjoy great popularity for making cities greener, cooler and healthier. Not least, the water buffering in plants and soil reduces the peak load on the sewage system – unless the rain loads are so heavy that plants and soil cannot absorb any more water.

If the green roof does not have a controlled water retention system, the excess rainwater will flow unrestrictedly into the public sewage system. However, the right roof drains can retain water in case of heavy rain, thus reducing the load on the sewage system within the roof drain regulations.

When installing the drain the perforated part is wrapped in geo-textile to keep the soil away from the drainage system.

BLÜCHER® offers a full range of drainage solutions in stainless steel for green roofs.
