Waste water technology to prevent the backflow of dirty water

Sewage technology from the manufacturer to prevent the backflow of dirty water and as a reliable protection for small animals and vermin in sewer pipes.

Our waste water technology to protect against backwater

In the field of waste water technology, we have specialised in backwater protection in waste water pipes. Our Stop Silent Light backwater protection from Lasso Technik AG is suitable for simple and quick installation in industrial and private sewage systems. In addition, it can be used as a frog and amphibian flap as well as an airtight odour valve in sewage technology. Furthermore, our technology for waste water is optimally suited for installation in drain pipes and control shafts with a back pressure of up to 0.5 bar.

Advantages of our waste water technology

Sewage technology for quick and easy installation in drain pipes and control shafts
Flood protection during floods
Waste water technology for the prevention of odour nuisance from the waste water system
Waste water technology for protection against the intrusion of amphibians and insects

Functionality of our waste water technology

Our waste water technology exerts pressure on the integrated membrane even with small accumulations of waste water media. This membrane in turn opens its sealing lip upwards and releases the flow for the dirty water. To close our special waste water technology, the sealing lip lies down when the waste water flow comes to a standstill. To prevent channel gases from escaping, the built-in rubber membrane is filled in the event of a backwater and thus presses against the pipe wall. As a result, a gas movement is no longer possible.
