Extension of the district cooling station seawater intake in Helsingborg, Sweden
- , Sweden
- Industrial infrastructure
- Completion: 2018
- Weholite and pressure pipes, DN630 – ID3,500mm
The largest prefabricated structure in Sweden
Choosing Weholite for the intake pipes was more self-evident. Compared to other materials and piping systems, Weholite is the most costeffective material with the highest durability and is the easiest to maintain. Öresundskraft required that neither the pipes nor the pump station would need chemical cleaning, but could be cleaned by pigging, a method that works well with PE pipes. Uponor Infra’s overall contract consisted of detailed engineering, project management, marine dredging and backfilling work.Creative support throughout the project The pump station made by Uponor Infra is the largest prefabricated structure in Sweden, at 23 metres long and with dimensions of ID/OD3,500/3,900mm. Uponor Infra’s overall contract consisted of detailed engineering, project management, marine dredging and backfilling work; the underwater installation of intake and outfall pipelines; land-based sheet piling; excavation, backfilling and asphalt works; the welding and installation of the intake pipes; the supply and installation of a prefabricated pumping station including sluice gates; filtration units; two pumps with a capacity of 3,600m3/h; and the circulation of water to the heat exchanger and outfall pipeline and then back into the sea chambers and poly pig devices.
The entire process – from the first drawing and calculations to the groundwork, complicated installation process and land restoration – was conducted by Uponor Infra and subcontractors. In 2017, the project was awarded the CCAC international environmental prize at the UN’s climate conference COP23 in Bonn.
