It is nothing new that the pipeline network has a huge backlog in Norway. There will soon be a doubling and tripling of water and sewage charges to clear the backlog. Norsk Vann estimates that the annual municipal rates for water and sewage for Oslo households will double to almost NOK 10,000 in 2040. According to the same long-term plan, residents of Innlandet, Nordland, and Romsdal would pay the most expensive water and sewerage tax in 2040, between NOK 20,000 and 30,000.
Inflow of stormwater and infiltration of groundwater into sewers is a constant operational challenge, but a water utility in Norway is gaining better understanding of its network with an innovative digital approach, says Marco Westergren, chief analytics officer at InfoTiles.
