BrugRegnvand.dk is operated by MRAIN, a Danish company founded in 2022, specializing in the import and distribution of rainwater solutions for the professional market.
MRAIN was established as a strategic spin-off from Nyrup Plast, which is now part of ScanPipe. The company is jointly owned by Mørkenborg Holding ApS and ScanPipe Holding ApS.
Rasmus Mørkenborg has led Mørkenborg Holding since 2011 and knows the industry inside out (as the third owner and second generation in the ownership of Nyrup Plast).
Mikael Lundgaard, director at ScanPipe and co-owner of MRAIN, joined as a strategic partner in 2023.
On a daily basis, MRAIN exclusively sells to dealers, consultants, architects, and contractors. However, the knowledge we have accumulated regarding sizing, product selection, and operation is made available here directly to you as a private homeowner.
The products behind the advice
We sell rainwater systems from Wisy and Dehoust – both manufacturers with decades of experience and VA-approved products. These are the same systems that our professional partners install for private and business customers throughout Denmark.
Bigger project on the way?
BrugRegnvand.dk is aimed at private homeowners. If you need professional-level technical advice or are working on a commercial plant project, you can contact MRAIN directly at mrain.dk.
Frequently Asked Questions
What can I use rainwater for in my home?
Rainwater can be used for toilet flushing, laundry, and garden watering. These are the three biggest water consumers in a household, besides baths and showers, and they do not require drinking water quality. Together, this can replace up to half of your water consumption.
Is it safe to wash clothes in rainwater?
Yes. Rainwater is soft water with almost no lime, which is actually an advantage for your washing machine and your clothes.
You use less detergent, and the machine is less burdened by limescale deposits. The system filters the water before it reaches the washing machine.
What happens when it hasn't rained for a long time?
Vi vil arbejde hurtigt på at sende din ordre afsted så hurtigt som muligt. Når din ordre er afsendt, modtager du en e-mail med yderligere information. Leveringstider varierer afhængigt af din placering.
Does it require a lot of maintenance?
No. You check the filter a couple of times a year, and the tank is inspected annually. This takes a few minutes and is comparable to the maintenance you already perform on your home.
What is a VA approval — and why is it it important?
A VA approval is an official Danish system approval issued by ETA-Danmark.
It documents that the entire system (filters, tank, pump, and control) has been tested and approved as a complete solution.
MRAIN is currently the only rainwater harvesting system in Denmark with a valid VA approval.
This gives you assurance that the system complies with building regulations and is continuously quality-controlled by the Danish Technological Institute.
