Our clients choose Kumulus to cut costs, reduce plastic, and produce water autonomously.

"Concrete solution for CSR projects"
Having water available directly on site means that residents no longer need to travel miles from the village to fetch water. What's more, the daily production of 20 to 30 liters of water allows us to avoid up to 500 kg of plastic per year, and up to 2 tons of CO₂ emissions. The changes are visible in terms of costs and the environment, since we no longer buy plastic bottles.
