Better and more cost-effective. These are the top benefits of our decentralized wastewater treatment solution.

Better

Removes all bacteria and environmental contaminants at the source
Reduced risk for sewage workers, public health, and the environment
More sustainable water management and enhanced biodiversity

More cost-effective

Pre-fabrication ensures high quality and reliability
Modular design enables faster planning and construction
‘Wireless’ solution – freeing up capacity in municipal sewage systems

A new era is coming...

… not just in Denmark but around the world. We need to redefine wastewater management to tackle infrastructural challenges posed by climate change, urbanization, and growing pressure on water supplies. The good news is that the solution is already in place!

What’topi?

Watopi is a Danish cleantech company specializing in decentralized wastewater treatment systems. Designed for hospitals, small communities, and households.

Our solutions achieve purification similar to drinking water level, ensuring safe, efficient, and cost-effective water management – with minimal environmental impact.

Best available technology

Recognized by the Danish Environmental Protection Agency as the ‘Best Available Technology’ (BAT), our solution offers a responsible and sustainable path forward.

Would you like updates on developments, legislation, and recommendations in the wastewater sector?

Danish hospitals pave the way

The technology has been tested and in operation for over 10 years at Herlev Hospital in Copenhagen.

We’ve fine-tuned every process from A to Z, so one thing’s for sure: You won’t find a more cost-effective, efficient, and well-documented system on the market.

In 2025, we will deliver the next hospital treatment plant – this time to the new Odense University Hospital (OUH) in Denmark’s third largest city.

”The decentralized solution at OUH will save at least 35 million kroner over the first 10 years, compared to traditional methods. It also frees up capacity in the municipal sewage systems for around 4,000 people,” says Jakob Søholm, CEO and Founder of Watopi.
