AF Gruppen has been chosen by Nedre Romerike vann- og avløpsselskap (NRVA) as the main contractor for the collaborative contract involving the expansion of the existing wastewater treatment plant in Strømmen, Romerike. Contract B2 pertains to construction and civil engineering work. In the first phase of the project, the collaboration will focus on optimizing technical solutions and project execution before the parties agree on a target price for the actual construction.

It is planned that the collaboration phase will take approximately one year. It is expected that a construction contract could have a value of approximately NOK 1 billion. The construction contract will only be included in the order backlog once the phase 2 contract is signed.
