Joint GRP Forces for Sustainable Stormwater System at Kraków Airport
Sep 26, 2018
Two powerful brands make an even more powerful solution: A combination of filament wound Flowtite and centrifugally cast Hobas pipes by Amiblu is being installed to build a new, highly efficient stormwater sewer system for Kraków Airport. The new underground infrastructure is an important cornerstone for the airport’s increasing importance in international aviation.
The airport’s continuous development and the increasing number of air operations also required an extension of the underground infrastructure – especially stormwater drainage was in important issue.
The nearby stream into which the rainwater had previously been discharged could no longer handle the growing amounts. It was therefore decided to extend the stormwater sewer system by new pressure lines which should lead the water over a distance of 3 km into the Rudawa river.
Eventually, GRP prevailed as material and Amiblu Poland was commissioned with the production of the required piping.
The investor can already draw on positive experiences with GRP pipes from Hobas which were installed under the airport in 2003 and are in trouble-free operation up until today.
The new stormwater sewer was realized with both Amiblu pipe technologies, Hobas and Flowtite, perfectly complementing each other: Filament wound Flowtite products were installed in open trench as pressure pipes for conducting the stormwater, while centrifugally cast Hobas pipes were used for stretches underneath roads where microtunneling was required.
Works at the airport started in November 2017 and are expected to be completed ahead of schedule at the beginning of 2019. The installation of this new drainage network will lay the foundation for future expansions of the airport, among others a new runway and aircraft hangars.
This will allow for the number of flight operations to increase and further strengthen Krakow airport’s international importance.
