The OFF Paris Seine, France’s first floating hotel, located on the Seine river in Paris, opened June 23, 2016. All of the hotel’s 58 rooms, including four suites, are equipped with Evac vacuum collection systems including 68 vacuum toilets, 68 vacuum interface valves, four stainless-steel vacuum drain channels and two vacuum collection units. In addition, the structure employs Evac vacuum grease separator.
Floating buildings, like boats and ships, cannot be built too high. There is limited room for toilet slopes in such structures, and the use of vacuum systems helps save space.
Evac vacuum systems for wastewater treatment “are lightweight and meet our ecological needs,” explains the architect of the OFF Paris Seine, Gérard Ronzatti. Evac vacuum toilets require only 1.2 liters of water per flush, compared to six to seven liters required by a conventional toilet. “The Evac system is simple to install, and easy to understand and manage,” he adds.
“We chose Evac for the reliability of its products. We have been working with the company for 20 years now,” says Ronzatti.
The architect also praises Evac’s team. “The support received by Evac representatives during the building’s conception and realization has been very important. It’s definitely Evac’s biggest advantage. It is paramount to be able to count on a whole team when building and testing.”
