Our system "Rainwater 2.0" combines a cistern and a rainwater retention basin into a single system. An intelligent control dynamically adjusts the fill level of the retention basin according to the current weather conditions. During heavy rain, the system automatically empties to ensure maximum capacity. In dry periods, the stored water is used for non-potable purposes. This not only saves drinking water and reduces wastewater charges, but also offers you a variety of options regarding the use of the available volume.
