Trondheim Water Pipe Renovation - Eight New Sections

Bytter gamle vannrør

Trondheim municipality is undertaking a renovation project to replace and renew several old water pipes to ensure a secure and safe supply of drinking water. The project targets eight specific sections this coming autumn, including parts of Lade Allé where pipes dating back to 1912 will be replaced. Other pipes in the renovation areas date from the 1960s and 70s and suffer from frequent breaks and leaks.

Oppdaterer åtte vannområder

The renovation initiative is led by the Municipal Technology department and Trondheim city maintenance teams, who annually assess which water pipe sections require upgrading. The selected areas for this phase include Saupstadringen, Utleirvegen, Bugges veg, Innherredsveien, Lade Allé, Rønningsbakken, Brøsetvegen, and Bukkvollan. Trondheim’s current water infrastructure comprises approximately 1600 kilometers of pipes, half of which are privately owned.

Rørfornying med minimal grave

The project employs a trenchless technique called pipe bursting, which involves excavating only at the ends of the pipes to pull new pipes through the existing ones. This minimizes surface disruption and shortens construction time. Temporary inconveniences may occur due to altered traffic conditions on roads and pedestrian/bicycle paths, and some households may experience brief water outages, with notifications sent via SMS in advance.

Reduserer lekkasjer. Sikrer vann

The primary goal of this infrastructure upgrade is to reduce leaks, which pose risks of water quality degradation, and to extend the lifespan of the water network. The municipality’s careful planning and use of less invasive construction methods reflect a commitment to maintaining reliable drinking water supplies with minimal impact on the community.
