Denmark's rainwater specialist
We have one mission: to make it easy to use rainwater in Danish homes — with world-class technology, advice, and service.
From idea to rainwater specialist
BrugRegnvand (UseRainwater) has roots tracing back to 1990 and is built on many years of experience with rainwater and solutions for the reuse of a resource that is otherwise often directed straight into the sewer system.
Throughout the years, the focus has remained the same: to make it simple and safe to collect and reuse rainwater. Today, we offer complete solutions for both private and commercial clients – from consulting and dimensioning to components, startup, and subsequent service.
BrugRegnvand.dk is today part of MRain.dk, where we combine Danish-produced tanks with proven German WISY technology. This allows us to put together solutions for various needs – from rainwater for garden irrigation in private homes to larger systems and professional service.
The goal remains the same as from the beginning: to turn rainwater into a usable resource – rather than something that is merely drained away.
