Totally Satisfied for Over 35 Years – Hobas Sewer Pipes Impress Testing Company

The sewer authority in the district of Gleisdorf (eastern Styria, Austria) put a combined sewer out to tender in 1979. What was planned was a rectangular channel with a gradient of 2 ‰ and a depth of up to 4 m as well as an egg-shaped section with a gradient of 1 ‰ and a depth of up to 4.2 m. Fortunately, the building contractor thought outside the box and submitted an alternative quotation with HOBAS GRP Sewer Pipes in DN 1200 and DN 1600. Although pipes made of glass reinforced plastic were not very well known at that time, the benefits of HOBAS Products convinced the client and the project was implemented with HOBAS Sewer Pipe Systems.

Time passed and over 30 years later an authorized and accredited testing company set about inspecting the sewer system. Primarily testing for leak tightness, they found no fault with the HOBAS Pipe Systems: “The positive test results – all the lines are leak-tight – show that we made the right decision”, says engineer Scharnagl, general manager of the Gleisdorf basin sewer authority, in a testimonial. As no problems whatsoever occurred in service with what was then a little known pipe material, the sewer authority installed many more kilometers of HOBAS GRP Pipes in the years that followed. “And everything to the sewer authority’s total satisfaction”, adds Scharnagl delighted with the excellent quality of the HOBAS Sewer Pipes.
