Ageing underground infrastructure

Ageing underground infrastructure
  • Poor state of the underground infrastructure requiring significant maintenance and renovation
  • Ageing underground infrastructure


Years old on average

The conditions of the underground infrastructure in Norva24’s current markets are overall in a poor condition because of lack of investment and delayed renovations resulting in a general investment backlog within the systems. In Norva24’s current markets, the average age of the underground infrastructure is approximately 40 years and, in some cases, as old as 150 years leading to damage to the sewers and increased leakage rates. This has an impact on the reliability and quality of the overall underground infrastructure which impacts the entire society. In Norway, Germany, and Sweden, approximately 0.5 to 1.2 percent of sewers will currently be renewed every year. Even though the quality varies, smaller municipalities normally have a less systematic approach to the maintenance of the underground infrastructure. The poor condition of the underground infrastructure is an important growth driver for the UIM industry, as the need for maintenance and renovation increases. In other European markets, which Norva24 currently are not established in are characterized by similar challenges with ageing underground infrastructure.

Condition of the underground infrastructure in Norva24 current markets

In Denmark the quality of the underground infrastructure is better than some other countries as annual investments of approximately NOK 11 billion have been made since 2012. As a result, the average system is of a younger age and has a significantly lower leakage rate compared to Norway, Germany and Sweden.
