We realised a new district heating pipeline between Altendorf and Pfäffikon SZ for Energie Ausserschwyz AG. The aim of the project was to supply the village of Pfäffikon SZ with sustainably generated heat from the Galgenen wood-fired power plant. Our PREMANT pipe system, which is characterised by high efficiency, durability and monitorability, was used for this.
Challenging implementation with clever planning
The project covered a total distance of 1.8 kilometres, on which both a supply and a return pipe were installed. This added up to a total pipe length of 3.6 km. In order to optimise the construction time and ensure the quickest possible completion, we decided to lay the pipes in parallel from two sides:
One team began the work in Altendorf, while another team started simultaneously in Pfäffikon SZ. Thanks to this strategy, the construction time was significantly reduced and a continuous heat supply was quickly guaranteed.
A particular challenge in this project was minimising the impact on the surrounding area, especially the sensitive natural habitat in the Lööliwald forest. In order to minimise the impact on the ecosystem, 80% of the construction section was thermally pre-stressed. This technique allowed us to largely dispense with expansion legs, which not only reduced construction costs but also ensured a particularly stable and durable pipeline route.
A successful project for a sustainable future
Thanks to close collaboration with all parties involved - from planning to execution - this challenging project was realised efficiently and on time. The new district heating pipeline now ensures a reliable, sustainable heat supply in Pfäffikon SZ and at the same time makes a valuable contribution to the environmentally friendly use of resources. Another example of how sustainable energy projects can be realised efficiently through clever planning, technical precision and an experienced installation team.
