Stormwater Management for Urban Development at Säterigatan, Gothenburg

When Gothenburg’s Hamnbanan railway line was moved underground, it unlocked an opportunity for one of the city’s most recent developments. A new neighborhood has now emerged in Säterigatan, featuring approximately 1,100 residential units, a preschool, commercial spaces, streets, parks, and well-designed walking and cycling paths. However, this urban makeover would not be possible without modern underground infrastructure. Pipelife Sweden was proud to supply a stormwater management solution that will serve Säterigatan’s community in the long run.

_{New district in an ever-evolving city}

The recent transformation of the Säterigatan area has connected the older Hisingen district in northern Gothenburg with the city’s new residential districts in the south, strengthening the link between the Lundby and Eriksberg neighborhoods.

The development’s overarching goal is to create a cohesive, sustainable urban environment that supports everyday life through green spaces, safe play areas and convenient mobility options for residents and commuters.

As part of the infrastructure expansion, a robust stormwater management system was required to handle large volumes of runoff while meeting stringent technical and site-specific requirements.

_{Key challenges included:}

• High ring stiffness requirements for a heavily trafficked area
• High storage capacity
• High installation speed to meet tight project timelines

_{Fully tailored stormwater system design}

To address the project’s complex requirements, Pipelife supplied a customized stormwater equalization reservoir with a total capacity of approximately 300 m³. The draft design was created by the municipality and tailored by Pipelife’s team to address production-specific parameters while adhering to the client’s specifications and ensuring full compliance with the project’s mechanical, hydraulic and installation requirements.

The final solution relies on Pipelife’s ID 1200 SN8 large-diameter pipes in lengths up to 18 meters. The underground reservoir consists of five distribution tanks, each with a descent to optimize flow. The pipe sections and chambers were pre-welded at Pipelife’s workshop in Ljung to simplify and speed up installation.

_{300-m³ stormwater reservoir installed in two weeks}

The underground stormwater storage reservoir was ordered at the end of April 2025, and the system was fully installed and ready for operation by the end of June. From the delivery of the first pipe, excavation and welding were completed in less than two weeks.

Close cooperation between the project’s welding contractor, Vabon, and Pipelife enabled smooth and efficient project execution. A long-reach excavator was used to handle pipes up to 18 meters in length, allowing for precise placement and therefore more efficient welding.

Additionally, the reservoir was laid in a single bed rather than strand by strand, further reducing installation time and costs. The final welding work was carried out by Vabon.

_{Project results and advantages}

Säterigatan’s newly installed stormwater system meets all technical and performance requirements for modern underground stormwater management.

_{The solution provides:}

• Reliable, high-capacity storage and flow equalization
• Long-term durability and structural integrity
• Suitability for high traffic
• Efficient and cost-effective installation
• A future-proof solution that supports further urban development

The Säterigatan project demonstrates how technical expertise, product specialization, and close collaboration among partners can enable sustainable stormwater infrastructure even in complex urban development areas.

The fully tailored underground solution now supports Gothenburg’s most recent transformation, ensuring reliable, future-proof stormwater management for a burgeoning neighborhood.
