The problem

Quite frequently our rain water pipes transport large amounts of debris through their outlets into rivers or lakes. In most cases this is caused by spillage or by wrongly or badly connected sewage pipes in separate sewer systems. Unfortunately, it is not always possible to localize the source of spillage or to repair the pipe network. In addition, street drains and private surface water drains carry contamination into the rain water pipe.

The result

Receiving rivers and lakes are polluted to a larger extent than is legal causing complaints, warnings and reports to the water authorities. In the past, expensive stormwater settling tanks were built as a partial solution to the problem.

The solution

With HydroSwitch Steinhardt provides a safe, tried and tested system to remove waste flows from the rain water pipe by diverting the waste flow automatically to the sewage pipe.

The advantages:

Extremely low investment expenses compared to stormwater settling tanks. Safe and continuous diversion of waste streams (including oil) to the treatment plant using a system which requires no external power source. It is self-operating with no additional operational expenses, has a very small footprint and is of a flexible design. For use in new or existing separate sewerage pipe systems.
