The advantages at a glance


Integrated buoyancy control - Suitable for groundwater installation

Highest quality of shape and material

Cost-effective installation - plug and play

Construction and design support the cleaning process

Strong as a bear thanks to an ingenious concept


The Grizzly has a unique shape with a very robust and intelligent ribbed structure. As a result, it easily withstands the lateral loads occurring underground and achieves an effect similar to a dowel in the ground. The Grizzly is thus suitable for all installation situations in groundwater. The enormous dimensional stability and integrated buoyancy control make the Grizzly unbeatable. This makes installation much easier for you. You save the entire effort of buoyancy control. The intelligent design of the Grizzly also supports the clarification process. Since the Grizzly is basically a rectangular tank, the wastewater has almost the same surface area at every filling level. This brings the advantage that the air lifts are much more efficient and use less energy to move the water out of the tank.
