Waste water / faeces / retention


Safe storage of waste water and faeces...

Our GRP tanks and containers can be stored in the ground or installed above ground.

The containers have three walls: The outer and inner walls are each completely tight and are permanently monitored by a leak detector.

The middle wall is made of special polymer concrete and provides stability: therefore, installation in the roadway area is also possible (depending on the manhole cover).

In areas with high groundwater levels, for example, the ROTAVER-The spherical tank can be equipped with an optional concrete buoyancy protection. The manhole integrated in the dome shaft allows easy access to the tank for inspections or tank cleaning even without dismantling the fittings.

The container or tank storage can be carried out completely by ROTA on customer request.VER be carried out.
