Veidekke: Building water treatment plant in Bærum

Veidekke has signed a contract today with Asker og Bærum Vannverk IKS to build a new water treatment plant at Kattås in Vestmarka in Bærum municipality. The contract is an execution contract valued at NOK 601 million excluding VAT.

In order to satisfy future requirements to drinking water quality, Asker and Bærum waterworks will build a new facility to treat crude water at Kattås in Bærum. The existing facility at Kattås currently gets its crude water from Holsfjorden. As the colour figure in Holsfjorden is increasing and sometimes exceeds the drinking water regulations’ recommendations, a new treatment plant needs to be built. The new plant will be able to supply large parts of Asker and Bærum with drinking water in an estimated normal situation in 2050.

Veidekke has been awarded the rock excavation and concrete contract in the project. Rock excavation involves blasting of approximately 182,000 m3 in access tunnels and four large halls. Concrete work will start next summer and is related to two large clean water basins for storage of around 25 million litres of water, two large filter basins with eleven metre high walls and several technical rooms.

“Ensuring that residents have clean water is an important task for society, so this is a major and significant project both for Asker and Bærum waterworks and for Veidekke. We have good expertise in this field and have recently completed a similar project for the City of Oslo at Maridalsvannet. We appreciate the confidence shown in us and look forward to starting the work,” says director Neal Nordahl of Veidekke Anlegg.

Construction work starts in August and completion is scheduled for 2025. The contract is included in Veidekke's order backlog for Q2 2022. Read more about the project here.
