Modernization of the gas high pressure line: securing the energy supply in Hagen

In the southeastern Ruhr area, more precisely in Hagen, the distribution network operator Westnetz drives an important construction project forward: the modernization of a gas high pressure line that connects the Volmetal to the Nimmertal. Around 4.5 kilometers of the line are laid underground in several construction phases. The new pipeline runs parallel to the existing line, which it will replace it in the future. This ambitious project also includes the technical challenge to overcome two steep slopes and to cross the A 45 motorway in Hunsdiek. In order to cope with this critical area, the method of horizontal flushing bore is used, which enables the laying of the gas high pressure line up to twelve meters deep below the highway. As localklick.eu , the work began in August, with the aim of completing the first construction phase of about one kilometer between Hunsdiek and Brechtfeld. The entire measure should be completed by mid -2026.

regulations and security standards

The establishment and modernization of such gas high pressure lines is subject to strict legal requirements. As bra.nrw.de , all necessary security documents must be displayed at least eight weeks before construction. In addition, an expert statement by a recognized expert is necessary. The new management may only be commissioned after the security has been confirmed by an expert. The Arnsberg district government is responsible for monitoring compliance with security standards and the proper operation, including regular controls of the operators, to ensure that all regulations are complied with in accordance with the GashdrlTGV and the rules of the DVGW (German Association of the Gas and Water Perform).

With the planned completion, the new gas high pressure line will not only ensure the supply of Hagen, but also support the needs of numerous industrial and commercial customers.
