The Oslo municipality has issued a boil water advisory affecting residents in neighborhoods such as Kjelsås, Brekke, Lofthus, and Grefsen, following a significant water main break on Lofthusveien. This incident occurred late Tuesday night, leading to a loss of water supply and subsequently prompting concerns about water safety. Residents are advised to boil their drinking water for a full day until 5:30 AM Thursday to ensure its safety for consumption.

The water and sewer authority emphasized that all water intended for oral use must be boiled first. This includes not only drinking water but also water used in coffee makers, for cooking, making ice cubes, and even for brushing teeth. Notifications have been sent out to all affected residents via text message, providing them with necessary instructions on how to handle the situation safely.

The municipality aims to prevent any health risks associated with consuming potentially contaminated water by advising residents to boil their water. This measure is standard practice during such incidents to eliminate harmful microorganisms. As the situation unfolds, the municipality is working to restore normal water services and will continue to inform residents about the status of the water supply and any required precautions for safety.
