Construction Contract for Sewage and Water System Upgrade in Trondheim

The Trondheim municipality is seeking suppliers for the fourth stage of the Ladebekken-Rosenborg project, which is part of a five-stage initiative aimed at separating sewage and renewing water systems in the area. This contract involves replacing existing water pipes, separating sewage installations, and restoring roads, as well as upgrading street lighting in several streets within the Rosenborg area. Additionally, OPI channels and cable installations will be established for Tensio. The project includes the construction of 3,400 meters of ditches for water and sewage installations and 1,300 meters for sand traps and service pipes. A new sewage system will be built to replace the existing combined system, and a new water supply plant will be constructed alongside the sewage facility. The contract also includes replacing parts of the water supply pipeline from the Kuhaugen basin to the city center. The new water and sewage pipelines will primarily follow the routes of the existing pipelines.
