Back in the mid-90s, we installed a large rainwater cistern to use the collected water for flushing the toilets. The recycling of grey water and the creation of internal water cycles are extremely important to us. These measures not only help us to conserve valuable drinking water resources, but also promote sustainable living habits and reduce our ecological footprint.
