The Evac wastewater handling solution is a closed and integrated system which consists of vacuum toilets, vacuum interface units, vacuum piping, vacuum collection tanks and wastewater treatment plants. The solution is based on vacuum, not gravity, which makes it possible to flush the waste horizontally or even vertically into overhead piping and, if needed, also around obstacles.
The Evac solution is environmentally friendly. With low water use – up to 80 % less than used in traditional toilets – it reduces sewage volumes and thus meets the requirement of small environmental footprint. The water coming from the Evac advanced wastewater treatment plant is pure enough to be used for irrigation or toilet flushing.
