Overview
- The hotel in Büchlberg drains its 1,200 cubic meter natural pool into a coated underground parking area during major cleanings, a practice described by the owner as an on-site temporary storage method.
- The owner told reporters that the pool is fully drained three to four times a year and that the system avoids roughly 6.5 million liters of fresh water use annually and about €25,000 in refill costs.
- Staff clear the parking area of cars, clean walls and floors with high-pressure equipment, and use high-capacity pumps to return the unchlorinated water to the pool on the same day.
- Videos of the filling have gone viral and guests sometimes watch and film the event, with local outlets reporting the spectacle and the owner’s sustainability framing.
- News reports note that the hotel’s account has not been independently verified and do not cite any regulatory inspections or water-quality tests, which leaves open the question of public-health oversight and possible scrutiny if others copy the method.
