Compression plug system

When planning and developing areas with new homes, many communities proactively integrate junctions and molded parts into their sewer networks so that these are equipped for future expansions. However, these junctions are often not used at all.

Open faulty connections or blind connections do not meet the guideline requirements of the German Association for Water, Wastewater and Waste (DWA). Today, there is a great need for action in closing these faulty and blind connections.

Schwalm developed a process which can be used to close these faulty and blind connections permanently afterwards. To do this, a compression plug is inserted into the connections by the robots Talpa FSR 1330 or Talpa FSR 2060 and braced in one work process. The closure works following the principle of a thermos flask seal.
