sØværket wins CITY’SCAPE Award 2026

The transformation of a former water treatment plant in Viborg, Denmark, has won the CITY’SCAPE Landscape Award 2026 in the Energy Landscape category.

 

sØværket transforms Viborg’s first water treatment plant into a multifunctional urban landscape, bringing together public recreation, district heating and rainwater management. Located at Nørresø on Sct. Kjelds Gade, the project retains and repurposes the site’s distinctive red waterworks building and later clean-water tank, allowing its industrial heritage to remain an active part of the city.

 

The former waterworks supplied Viborg with clean drinking water in the early 1900s. Today, its historic wells provide a new source of energy: the building now accommodates a heat pump system that extracts heat from the old wells and supplies local district-heating consumers.

A landscape shaped by water and technology

The CITY’SCAPE Landscape Award recognises landscape projects that contribute new perspectives on the relationship between landscape, infrastructure and the built environment. sØværket demonstrates how existing technical facilities can be transformed into places that serve both the city’s everyday needs and its public life.

 

The project makes the site’s past and present functions accessible to residents and visitors. A phosphorus purification system has been installed in the former clean-water tank as part of the heat-production system, while its roof has become a setting for play, recreation and gathering.

 

Water pipes are incorporated into the design of tables and benches, creating tactile references to the site’s former role as a water treatment plant and its current energy and water-management functions.

 

“sØværket is a transformation that builds on the qualities already present on site. By preserving and repurposing the former waterworks and clean-water tank, we have given a historic technical facility a new role in the city as a place for recreation, rainwater management and energy production,” says Julian Weyer, Architect and Partner at C.F. Møller Architects.
