Vuna – a world of ideas

We plan and build your water and sanitation system of the future today. From urban to alpine.

About us

Vuna develops decentralized wastewater systems and circular sanitation systems for remote holiday homes and tiny houses, plans the treatment of cabin wastewater, and enables innovative solutions for urban areas. From total wastewater treatment to greywater recycling and rainwater reuse, Vuna has already implemented several (waste)water systems. We also offer nutrient recycling: with the recycled fertilizer Aurin, on the one hand, and with fecal composting, on the other. In the latter, excrement is converted into humus through worm composting, which can be used as a nutrient-rich soil improver. The product range is complemented by drinking water filters and other drinking water treatment systems that ensure drinking water quality.
