I was hired to design this large-format calendar for the anniversary of Hardwasser AG, whose business is artificial groundwater recharge in the Basel Area. The company is using water from the Rhine river, which is naturally filtered through the soil and eventually becomes drinking water. During the course of a year, I took hundreds of water photographs at the river and in their facilities, thirteen of which we selected. The calendar was produced in offset printing. In collaboration with Angelo Lüdin & Gregory Vines.
