République et Canton de Genève
Geneva
The Republic and Canton of Geneva offer solutions for better water management and consumption, including collecting approximately 113,000 liters of rainwater each year in water tanks, which is used as an alternative to drinking water for flushing toilets, while also demonstrating how buildings can use rainwater to save water and help cool down cities.
Would you throw money down the toilet, into your garden, or across your car? No, because it sounds stupid to waste precious resources, right? However, that’s essentially what we do when we use clean, treated drinking water for our activities like gardening, washing vehicles, and flushing toilets. It’s not only wasteful—it’s unsustainable, especially as we know freshwater is under important and increasing pressure. The daily global average water consumption in residential areas is up to 600 litres in North America and Japan, between 250 and 350 litres in Europe, and between 10 to 20 litres in Sub-Saharan Africa (1). Additionally, about half of the world’s population experienced severe water scarcity for at least part of the year in 2024 (2). A smarter and more sustainable solution is to collect and reuse the natural and free resource of rainwater through water tanks. In the long term, rainwater harvesting would first reduce your reliance on municipal water supply and lower your bills, but most importantly, lighten your environmental impact. With this simple approach, we can stop wasting drinking water where it’s not needed and start using what nature gives us for free.
