New lake in the town of Gedved helps fend off water from private properties

New lake in the town of Gedved helps fend off water from private properties

21.February 2020
In the small town of Gedved north of Horsens, Jutland, the Danish Nature Agency has established an almost 42-hectare stormwater wetland area, including a restored Gedved Lake. The purpose of the project is to reduce the amount of nitrogen that ends up in Horsens Fjord. At the same time, the project has improved the natural habitat, i.e. by introducing a wildlife corridor. Horsens Municipality has also designed the new stormwater wetlands to serve as a buffer during heavy precipitation events. Downstream of the new wetlands, properties near Gedved Mill used to be troubled by flooding. However, after establishment of the new lake, even the record amounts of rain during the autumn of 2019 did not cause problems. How substantial a precipitation event the lake can cope with has not been calculated.
New green oasis will keep basements dry in Kolding

New green oasis will keep basements dry in Kolding

28.January 2020
In downtown Kolding, the local utility company and the municipality worked together with the city’s residents to establish a multipurpose urban natural landscape. In the future, a retention basin will manage the area’s stormwater runoff, taking some of the load off the sewer system and preventing roads and basements from the worst impacts from flooding.
Large joint climate change adaptation project along the Store Vejle Å watercourse west of Copenhagen

Large joint climate change adaptation project along the Store Vejle Å watercourse west of Copenhagen

28.January 2020
Simple technical solutions have prepared neighbours to Store Vejle Å, a watercourse in the suburban district of Vestegnen west of Copenhagen, for more extreme rainfall events in the future. Furthermore, part of the riparian zone has been upgraded with more natural areas and recreational opportunities. Six municipalities and four utility companies joined forces to provide climate protection along the watercourse.
Næstved Municipality - Climate lakes established and Ellebækken re-meandered

Næstved Municipality - Climate lakes established and Ellebækken re-meandered

28.January 2020
To prevent Ellebækken to dry out in the summer and being flooded in the event of large rain, two large lakes were established and the brook was re-meandered.
The City of Vejle protects against climate change and establishes a new urban space

The City of Vejle protects against climate change and establishes a new urban space

17.October 2018
Downtown Vejle lies in a river valley surrounded by some of the steepest slopes in Denmark, and at the bottom of a fjord flowing out to the Kattegat. Downtown Vejle has experienced repeated flooding. Through broad and efficient collaboration, the city has managed within few years to establish pumps, sluices, distribution works and a wildlife corridor. At the same time, the city has turned the water into something that adds value to the city in a new and attractive urban space that has been well received by residents. Flood-proofing Downtown Vejle is the first among several projects to protect residents, buildings and infrastructure against flooding.
Copenhagen Zoo retains water

Copenhagen Zoo retains water

17.October 2018
At Copenhagen Zoo in Frederiksberg, wombats, kangaroos and Tasmanian devils live on top of an infiltration basin with 650 infiltration cells and an overall volume of 142 m3. The infiltration cells collect, percolate and retain rainwater. The Zoo is situated on the top of Valby Bakke (Valby hill) and since 2015 the infiltration bed has helped protect the residential areas at the foot of the hill against the worst effects of cloudbursts. The infiltration system also helps the Zoo save on water consumption, as rainfall in general is now also collected and used to clean out pools and animal enclosures.
New, permeable road surfacing in Frederiksberg instead of expensive drain pipes

New, permeable road surfacing in Frederiksberg instead of expensive drain pipes

16.November 2017
In 2011, the greater Copenhagen area was hit by a massive cloudburst event. Helenevej, a small cul-de-sac to the larger Bülowsvej road in Frederiksberg Municipality, was flooded. Today, the road has new climate-friendly road surfacing designed to absorb large amounts of water.
Sluice system at Aarhus River reduces the risk of flooding

Sluice system at Aarhus River reduces the risk of flooding

8.June 2016
The City of Aarhus has established a sluice at the mouth of the city's river, Aarhus Å. The sluice protects central parts of Aarhus against flooding. The construction serves two purposes. Firstly, four sluice gates will protect the city against intruding seawater during high sea levels, and, secondly, six powerful pumps will pump water away from the river and into the sea during cloudbursts. The sluice can pump as much as 18,000 litres of water per second from the river and out into the sea. In order to provide further protection for the low-lying parts of the city during high water levels, the two streets, Havnegade and Europaplads, as well as the area around the sluice itself, have been raised. The construction costs totalled DKK 46 million. A traditional solution, with underground retention basins to retain the water, would have cost ten times this amount.
Slotsholmen in Copenhagen is now well protected from the next cloudburst

Slotsholmen in Copenhagen is now well protected from the next cloudburst

7.June 2016
In order to protect the area around Slotsholmen, a small island district in Copenhagen city centre and the seat of national government, against seawater during extraordinarily high water levels, the quay walls around Frederiksholms Kanal have been reinforced and raised over the years. However, the intention to protect the city against seawater has had the unfortunate consequence that during heavy rainfall the rainwater cannot run out into the harbour. Copenhagen experienced this during the intense cloudburst in the summer of 2011, when many buildings around Slotsholmen stood under water. Steps have now been taken to prevent this from happening again. During very powerful rainfall events and cloudbursts, the rainwater is today directed via grates along the sides of the road and via underground drains to an opening in the quay where the rainwater runs out into the harbour. At the outlet there is a non-return flap valve, which ensures that the water can only run out and not in. During very high water levels, the valve shuts and flooding is prevented.
Green rainwater solution creates a new beautiful urban space in Copenhagen

Green rainwater solution creates a new beautiful urban space in Copenhagen

6.June 2016
Tåsinge Plads, a square in the district of Østerbro, Copenhagen, has been protected against heavy rainfalls. A total of 2,000 square metres of asphalt and a rather boring piece of lawn have been removed and transformed into a green oasis that can retain and collect rainwater from an area of road and rooftops half the size of a soccer field. So there is no longer the same risk that sewers will overflow in the event of powerful rainfall, because rainwater from the square and surrounding roofs will now drain into a series of rainwater basins or it will seep down into flower beds planted with plants that tolerate salty water. At the same time, residents in the area now have a new, exciting urban space; a meeting place for adults and a playground for children.
