Oslo municipality has initiated a EUR 2.5 billion project for the development and construction of a new water supply solution to provide service to roughly 700,000 of its citizens. The project is scheduled to be completed in 2028 and is the largest investment ever undertaken by the city of Oslo.
CMS Kluge is continuing to advise Oslo municipality as it progresses the various phases of the project.
The project consists of three main parts:
- Creating two tunnels, approximately 9 km long, between Holsfjorden and Oslo for water transport;
- Building a new water treatment plant in Oslo; and
- Constructing new water mains for the distribution of clean drinking water.
The New Water Supply Oslo Project will ensure access to a second source of drinking water for Oslo, in the event that the existing water source or water treatment plant fails. In addition, as the city’s population expands in the coming decades, the project will meet the expected increase in demand for drinking water. Amongst the main suppliers to the project are Skanska (Sweden), Sarens (Belgium) and Herrenknecht (Germany).
