New pipe bridge strengthens regional district heating network
BRUGG Pipes has supplied pre-insulated district heating pipes for the highway bridge over the A4. This will close a gap in the Ennetsee district heating network and supply communities in the Zug region.
BRUGG Pipes from Kleindöttingen, part of the Brugg-based BRUGG Group AG, has supplied pre-insulated district heating pipes for a crossing of the A4 highway. The bridge element between Holzhäusern and Rotkreuz was lifted into place at the end of October, according to a press release. During assembly, two 48-metre-long pipes suitable for bridge structures were installed. They weigh 4.9 tons without water.
The pipe bridge connects existing and new sections of the Ennetsee heating network. Further districts and commercial locations in Rotkreuz ZG, Cham ZG and neighboring areas are to be connected to the district heating network. The client for the project is WWZ. The company B S AG was responsible for the planning and construction management of the bridge, supported by Hodel SHLK AG as the pipe constructor. “I am delighted with how WWZ, B S, Hodel SHLK and the other partners implemented this project in a spirit of partnership and with the utmost precision. Laying our pipes like this with our own bridge is definitely not an everyday occurrence. I am all the more pleased that the installation was successful and that our pre-insulated pipe systems are now supporting the expansion of the Ennetsee heating network and decarbonization,” said Martin Rigaud, CEO of BRUGG Pipes, in the press release.
WWZ uses the waste heat from the Renergia waste incineration plant in Perlen LU as a heat source. Cham is also to be supplied with district heating from the project by fall 2026. Overall, the expansion of the network is expected to save around 12,000 tons of carbon dioxide per year.
