HydroSwitch® Sewage Switch

The cost-effective and reliable solution

for keeping misroutes out of stormwater canals

The Problem

The transportation of wastewater in stormwater canals happens all too frequently. In most cases this is caused 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. 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 but brought only limited cleaning effects.

The Solution

With the 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 Steinhardt HydroSwitch® is a clever combination of simple construction (shaft in stormwater canal) and durable Steinhardt stainless steel components. Extremely effective and very economical!
