Rehabilitation of Potable Water Pipelines in Budapest
A section of Budapest’s potable water network was rehabilitated in 2011. Although over 100 years old, the concrete channel DN 1700 still had good structural properties. Nevertheless, it showed typical damages on the inside surface. As the customer was very satisfied with the already installed HOBAS Products, he opted for HOBAS again.
The pipeline was opened every 150 to 200 m and relined from both sides. The contractor used hydraulic equipment to facilitate the coupling of the pipes. And again, thanks to the excellent features of HOBAS Pipes, only a small number of workers was employed in the installation: One person moved and lifted the pipes, two inserted them into the old pipeline and joined the pipes, and one more person assisted wherever help was needed. Thanks to the light weight and easy handling of the 6-m-long HOBAS Pipes DN 1000 to 1500, the installation progressed quickly and the entire length of 1.1 kilometers was finished within 1.5 months only. HOBAS also delivered shafts to complete the system; perfectly organized deliveries according to the customer’s needs rounded off this successful project.
