Climate park in Vejle to keep basements and roads dry

28.April 2021
Vejle Municipality, the local water utility company and a local housing association have joined forces in a climate change adaptation project to prepare some of the eastern district of Vejle for more extreme rainfall in the future. The climate project consists of five sub-projects to ensure rainwater is effectively channelled into Vejle Fjord rather than into basements and onto roads. The new area will also offer a recreational space for play, ball games and outdoor relaxation. The first sub-project is the Climate Park: a green 750-square-metre wedge with an open, several-hundred-meter-long water channel. The Climate Park sub-project is part of a larger climate project in the eastern district of Vejle, the aim of which is to channel rainwater runoff along a 3.5-kilometre-long conduit from the higher-lying northern part of the district downhill into the fjord. The entire water passage can cope with as much water as will fall during an 80-year to 100-year rainfall event, projected to the year 2100.
Storm surge protection and new harbour environment in Svendborg

Storm surge protection and new harbour environment in Svendborg

28.April 2021
The Blue Edge (Den Blå Kant) will be the residents of Svendborg's new common harbour space between the city and the sea. Three sluiceways and a belt of fixed and mobile dikes along the outer perimeter of Svendborg Harbour will protect the area against storm surges of up to three meters above mean sea level. Svendborg city lies elevated compared to the harbour. The project will therefore also establish several emergency flood channels leading stormwater runoff from the city directly into the harbour basin. The harbour basin can be used as a reservoir to protect the harbour area onshore against flooding during cloudbursts when the city sends cascades of water downhill. Svendborg Municipality estimates the total project cost to be several hundred million kroner. The municipality therefore also expects the full project will take more than ten years to complete. Once complete, however, the harbour area of Svendborg will be able to withstand a 100-year storm surge event and a 100-year rainfall event.

The Enghaveparken Climate parken in Copenhagen now attracts both people and stormwater drainoff

28.April 2021
The more than 90-year-old green oasis, Enghaveparken, in the Vesterbro district of Copenhagen has been transformed following an extensive renovation project. The park is now one of the largest climate change adaptation projects in the City of Copenhagen. The project to renovate Enghaveparken was a collaboration between the municipality, Områdefornyelsen Vesterbro (municipal district renewal initiative) and HOFOR – Greater Copenhagen Utility. Several foundations also contributed to the project, and residents in the area were invited to be a part of the project as well. Following the project, Enghaveparken can now retain 22,600 cubic meters of stormwater runoff, and normal rainfall channelled to the park can be reused. In addition, major upgrades have been made to Enghaveparken, so that the park now has improved facilities for play, recreation and nature experiences. All renovation and renewal work was carried out with respect for the park's original architectural characteristics.
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

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

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.

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.
