Wastewater Calendar 2026

Clean water is not a luxury. It’s life.

The 2026 Wastewater Calendar is a desk calendar that celebrates the places where water is brought back to life – with twelve unique photographs from the world of wastewater treatment.

As every year, all proceeds will be donated. This time to the WaterFoundation, supporting access to clean water and sanitation for people around the world.

A calendar that not only looks good – but does good.

Together, we make water visible and help where it’s needed most.
