At la grée des landes water is at the very heart of concerns, and every effort is made to save it. Water from the relaxation pool is recycled then used in the restrooms, while water from the Wellness Space swimming pool, along with rainwater, is used to water plants and flowers. The remaining wastewater is recycled in the hotel park via a filter basin surrounded with reeds to ensure aeration and development of bacteria, then into a pond with filter plants to remove all impurities before flowing into the soil. It should be noted that the shower heads in the bathrooms help to halve water consumption!
