VERKET

How can Ulricehamn’s wastewater treatment plant and the surrounding area be transformed for future needs? The project VERKET, a collaboration with Ulricehamn municipality, explores how innovative design and management can improve the use of seemingly outdated resources. 

Many municipalities in Sweden face major challenges regarding technical infrastructure and systems. Underdimensioned and outdated facilities are increasingly strained by the growing risks of heavy rainfall and flooding. New infrastructure, such as water and sewage facilities, requires significant municipal investments, while existing structures must be maintained and integrated into urban and community development. Often, these sites have been closed to the public but, following decommissioning, could become part of public spaces and everyday environments.

The project focuses on the Fiskebacken area and, more specifically, the Ulricehamn wastewater treatment plant, built in 1955. While the facility has been upgraded over time, population growth and increasing purification demands make it unsustainable to continue expanding on the existing site. With the municipality’s plans for a new wastewater treatment plant, opportunities arise to repurpose the current facility and its surrounding area.

Through an open call, team VERK-SAM was selected to conduct a site inventory, analysis, and develop a management plan, including strategies, methods, and design proposals. The project aims to demonstrate how the wastewater treatment plant’s structures and surrounding environment can be cared for and managed as a resource when the area transitions from a closed industrial site to a public space.

VERKET also aims to provide Ulricehamn, along with other municipalities facing increased infrastructure demands, with tools and knowledge for the long-term sustainable planning and management of existing resources.

From October 2024 to February 2025, team VERK-SAM has explored the Ulricehamn wastewater treatment plant and its surroundings.

The work began with an inventory based on the recognition that existing structures hold both cultural-historical value as expressions of the society that built them and serve as an important resource in a time of transition. Using methods such as archival research, site visits, workshops, interviews, and sketches, the team identified key strategies for further exploration.

Based on this inventory, team VERK-SAM developed a report containing a management plan. The plan consists of three main strategies, a methodological framework, and a design proposal for the site. By focusing on 1) water as a resource 2) strengthening the site’s green ecosystem
3) repurposing the wastewater treatment plant’s buildings and structures, team VERK-SAM proposes that Ulricehamn gradually transform the site.

The proposal envisions the wastewater treatment plant evolving into a multifunctional public space for Ulricehamn residents and visitors—a place for recreation, learning, and food, both in production and consumption. It fosters circular synergies between built structures, water, and greenery, supporting biodiversity and ecological resilience while strengthening the local community.
