Sewer Sealing Cushion Type 1-3200 in action

After an almost one-year planned construction phase, the city of Steyr in Austria completed the construction of the relief sewer to the river Enns. Thanks to the help of our Sewer Sealing Cushions, the water service company WDL, a subsidiary of the Energie AG water group, has tested the pipe sections with diameters up to three meters.

Already in March 2016, the Austrian company WDL purchased from us a set of LAMPE Sewer Sealing Cushions type 1-3200 for leak tests with air or vacuum in high-volume channels up to 3200mm.

At the end of 2016 the WDL was commissioned to carry out the leak test for the new section of the sewer network in Steyr, Austria. Two sectures with 3 meters (DN 3000), a secture with 1.6 meters (DN 1600) and a secture with a diameter of 1.5 meters (DN 1500) were tested for tightness under pressure.

The new sewers built on this section of the Steyr sewer network serve as relief structures for rain events. Due to the help of our Sewer Sealing Cushions the leak test proved to be on schedule and to full satisfaction.

After the successful leak test, the relief channel was put into operation in December.
