A well-known automobile importer is planning to build an extension in the industrial park at Härkinger-Kreuz, requiring the relocation and extension of the existing trunk main and fire-extinguishing water pipeline to secure the supply of drinking water and fire-extinguishing water. DN 200, K 9 vonRollecopur ductile iron pipes with internal polyurethane lining and external polyurethane coating will be used for the 600 m long pipeline.

Additionally, the Gerlos ski resort in the Tyrol has upgraded its snow-making systems, with around € 4 million spent on the project, including the installation of 9 km of ductile iron pipes with nominal sizes from DN 80 to DN 400 and pressure ratings from PN 40 to PN 100.

Other projects include the relocation and rehabilitation of two drinking water pipelines, and the relocation and extension of trunk and fire extinguishing water pipelines for a new industrial construction project. The HWS supplies around 238,000 residents with drinking water, and a rehabilitation of the older drinking water pipelines is essential to guarantee a stable water supply.

The town of Raunheim is building a ring road which crosses the existing DN 1000 trunk main, and Hessenwasser has moved a length of around 145 m of its drinking water pipeline out of the danger area. Ductile iron pipes with BLS restrained push-in joints were used, eliminating the need for concrete thrust blocks.
