Kvarnängens stormwater park
Kvarnängens dagvattenpark är en anläggning mitt i Boden som tar hand om regn- och smältvatten – det som kallas dagvatten. Den gör nytta för miljön, men är också en vacker och lugn plats att besöka.

What is stormwater?
Stormwater is water that flows over the ground when it rains or when snow melts. In nature, the water is absorbed by the ground and naturally filtered. In cities, the ground is often covered with asphalt, stone, and other hard materials. This means the water cannot soak into the ground but instead flows into drains, ditches, and waterways.
Stormwater in cities needs cleaning
As stormwater flows over roads and parking areas, it can pick up litter and harmful substances – such as oil, metals, and chemicals from vehicles. That’s why it’s important to collect and clean stormwater properly, so it doesn’t pollute nature or cause flooding.
How Kvarnängen Stormwater Park works
The stormwater park is located by the popular area of Kvarnängen. Here, the municipality has created a solution that both cleans the water and provides a pleasant place to visit.
How the water is cleaned – step by step
When the water enters the park, it first passes through a small pond where heavier particles sink to the bottom. The water is then led through shallow green ditches, called swales, where plants help remove nutrients and metals. The water level in the pond is regulated by a so-called “monk,” a control structure that makes sure the water flows onward at the right pace.
A place for play and nature
A special area functions as a floodplain when it rains heavily. Here, stepping stones invite children to play while also slowing down the flow of water. Around the entire park, meadow flowers and wetland plants grow, making the area both beautiful and alive.
A collaborative municipal project
The project was developed by the Municipality of Boden through cooperation between several departments. Students from Björknäsgymnasiet’s construction and civil engineering program also helped by building a bridge over the stream. The project received financial support from the Swedish Environmental Protection Agency.
How you can help
Everyone can help keep our stormwater clean. Here are a few simple tips:
- Wash your car in the right place. Don’t wash your car on the street or in your driveway. Use a car wash that has an oil separator and extra cleaning steps.
Dirty wash water contains oil, metals, and chemicals that regular treatment plants can’t remove. - Choose environmentally friendly products. Use eco-labeled car care products. Avoid petroleum-based degreasers – they are usually only needed during the winter.
- Let the water soak into the ground. If you have a garden, let rainwater flow onto grass or flowerbeds instead of the street. This helps nature clean the water naturally.
