Technical paper: “Quick-Pig” for the municipality of Glattfelden 🇨🇭

Patrick Frei, the municipality’s wastewater treatment supervisor in charge, decided to clean the pressure pipe and relies on the gentle pigging process. The biggest problem with pigging is that the pig has to be inserted into the pipeline, which means that the existing pipeline has to be dismantled and opened. This is a laborious process, which Frei was able to improve significantly with the Quick-Pig pig trap.

Technical article: The ” quick pig ” establishes
Pigging a pipeline must become easier and safer! Without a complex manhole, without time-consuming ventilation of the manhole, directly from the street, made of PE 100 and corrosion-free. With these requirements, Hamburg’s municipal drainage system (now Hamburg Wasser) approached Reinert-Ritz GmbH from Nordhorn. The fittings manufacturer developed a station that enables fast, safe pigging without a manhole and has been used successfully in various projects to date.
