Vuna – a world of ideas

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

About us

At Vuna, we develop decentralized and circular sanitation systems for remote holiday homes and tiny houses, we plan drinking water and wastewater treatment systems for mountain huts, and we generate innovative solutions for circular water management in 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, excrements are converted into humus through worm composting, which can be used as a nutrient-rich soil improver. The product range is complemented by drinking water treatment systems that ensure drinking water quality.
