In the Morbihan region of France, where a drought crisis has led to the closure of most automotive wash businesses, only one remains open—Oto Naet in the city of Vannes. This decision comes as local authorities implement strict water conservation measures to address the severe shortage of water resources. Oto Naet has been operating under unique conditions since 2016, when it began collecting rainwater to use in its car wash services. This approach allows the business to reduce its reliance on municipal water supplies, which are under increasing pressure due to the drought. By capturing and storing rainwater, the car wash is able to maintain operations without contributing to the strain on local water sources. In addition to rainwater collection, Oto Naet has also implemented a water recycling system for the past three years. This system treats and reuses water from previous washes, significantly reducing the overall amount of fresh water needed. The combination of these two strategies—rainwater harvesting and water recycling—has allowed Oto Naet to continue providing its service while adhering to the region’s water conservation requirements. The situation in Morbihan highlights the broader challenges faced by communities experiencing drought conditions. As water becomes scarcer, businesses and individuals are being encouraged to adopt more sustainable practices. Oto Naet's model demonstrates how innovation and environmental responsibility can work together to support economic activity even under restrictive conditions.
