Klimaspring projects

Since early 2014, Klimaspring has initiated, completed and planned 14 pre-projects, seven of which have since become actual projects contributing to future solutions for managing increased amounts of rainwater. By mid 2015, Klimaspring stoped launching new development projects.

You can find an overview of all pre-projects and projects here (in Danish only).

An English description of the seven projects can be seen below. 


Increasing nature and biodiversity in towns and cities

Biowater re-introduces the village pond as a rainwater reservoir in dense urban areas. The village pond is a meeting place for residents to enjoy, while allowing greater biodiversity in cities and towns as a natural habitat for animals and plants. 
Biowater is a holistic solution, which integrates water management with human recreation, nature and biodiversity into a single unified service. The aim is to re-create the village pond as a combined rainwater reservoir, a space for people to relax and a living space for animals and plants. The key to the concept is that it is modular and scalable, which is easy to implement, is inexpensive and which combines the best from standardised dry well solutions with high volume capacity and unique construction projects with the possibility for local and site-specific adaptation.
Biowater is offered in two different versions. In one version, it is in ground level, so there is free transition from the ground to the reservoir. In the second version, it is raised above the ground, where Biowater becomes part of the urban space. The above-ground version of Biowater is selected for those locations where it is not possible to excavate in the ground. This model will typically be used in dense urban areas, where there is a lot of infrastructure in the ground and where seepage is not possible.
Biowater manages rainwater from roofs. It is possible to choose whether there shall be seepage from the installation – which if so, will occur in the reservoir’s sides above the permanent water level. The rainwater is managed through a combination of storage, delay, evaporation and seepage, where possible.
The project is not just an answer to the need for climate adaptation in cities and towns, but also a supplement to the decrease of natural areas in the open countryside, which means that animals and plants increasingly are dependent on towns and cities to be able to live and survive. Nature inside urban spaces is therefore becoming more and more important for biodiversity. Biowater can be built on large and small scales, for example in squares, courtyards and gardens.

Easier management of flooding hazards

“Dynamiske oversvømmelseskort” (interactive flood risk tool) makes it easier to manage flooding hazards more precisely when new urban areas are planned and emergency situations need to be dealt with. 
The idea behind “Dynamiske oversvømmelseskort”, is to develop a powerful online flood risk tool targeted at local governments and water utilities. The easy to use tool allows for interactive flood risk estimation and planning, based on high-resolution terrain data. The software is a further development of the technology used in Skybrudskortet© and it will incorporate data from sea, stream and hollows. 
Current digital models for analysing flooding are far from ideal, partly because they are not continually updated and partly because they are difficult to use by non-experts. Therefore, the aim is to develop a user-friendly planning tool, which allows for the processing of new data on an ongoing basis. The tool’s dynamic and user-friendly design will ensure that a broad group of stakeholders in municipalities and utilities, who are not necessarily experts in hydrological modelling, can use the tool.

Digital platform for joint action

“Samvejr” (Shared Weather) links digital possibilities with social action, so that it is easy to take part in local adaptive activities, whether proposing or receiving ideas for specific action.
The weather is changing. Increasing occurrences of heavier rainfall continue to cause flooding leading water from the drainage system into people’s cellars. As citizens and a society, we have to act. But the problem cannot be solved by excavation alone. An extension of the drainage system is both a costly solution for society and extremely discomforting for those people living in streets that have to be dug up. Luckily, there are cheaper and better alternatives.
“Samvejr” is a digital platform that informs and facilitate local action. By creating a shared digital and social space where people can propose and request inspirational tips and solutions to stormwater management, it mobilizes human action as an effective climate adaptional ressource.
“Samvejr” is a digital platform, which promotes active collaboration between authorities and citizens on local climate change adaptation. It does this in various ways, such as connecting professional experts with highly engaged people in the affected areas. “Samvejr” aims to make climate change adaptation a shared concern and not just a public authority task. 
The aim of the project is to connect digital possibilities with social and user-driven action and in this way allow citizens to actively participate in climate change adaptation by offering them a platform, from which they can contribute with concrete ideas and action at a local level.
Using the platform, citizens, authorities and others can therefore as a group share knowledge, discuss, plan and facilitate local climate change adaptation activities, and the platform will among other things, include tools for dialogue, guidelines and cases, which can be used for inspiration and help to create shared understanding of the problems between the different parties.

Making cellars and entrances safe from stormwater

“Skybrudsklappen” is a fast-acting and effective automatic barrier that closes off basement stair-cases and entrance areas to protect them from flooding.
Cellar stairs and entrance areas are often particularly exposed when stormwater occurs because the water can become trapped. With cellar stairs in inner city areas, it is often caused because establishing a raised edge around them is not practical or allowed because of their positioning in the pavement. 
The aim of the project is therefore to develop automatic flooding barriers that can safeguard cellar stores in inner city areas and in town centres, but which also generally safeguard ground floor entrances against flooding and subsequent water penetration.
“Skybrudsklappen” functions by automatically activating the barrier around the entrance when water is detected pooling on the ground. The solution functions without electricity or other external supply, which reduces the costs of installation and increased operational reliability. An important aspect of the development project is incorporating accessibility into the solution, as well as working on how the solution can be developed in harmony with a building’s heritage.

Smart realtidsstyring af vandsystemer

Controlling water in the drainage system

“Smart realtidsstyring af vandsystemer” (Smart real-time control of water systems) makes it possible to automatically control the wastewater system in real time, so that the water is transported to where there is capacity.
The struggle to deal with increased rainfall is not only taking place in the physical world, to an equal extent, it is taking place in the digital world. Therefore, the project aims at further developing an IT-supported system for the real-time monitoring, modelling, warning and management of rainwater in both drainage systems and on the ground. 
This reduces the need to invest in enlarging and upgrading the existing drainage system, and so the project’s primary aim is to make managing rainfall less expensive. At the same time it aims to open up new possibilities for the use of water on the ground. The new software solution will be part of DHI’s MIKE products and consultancy services, and will have a wide range of applications in cities and towns throughout the whole world. 
The development of the new software system is based on the concept of smart control of water systems. By comparing information on where the water is at all times, and at the same time predicting where and how much rain will fall in the immediate future, it will be possible to find the optimal solution for the entire city or town’s water system, and in this way efficiently utilise reservoirs and purification plants.

Activating the pavement in water management

“Klimaflisen” (Climate Tile) is a pavement system which consists of an innovative underground water management system, which is directly connected to recreational elements
in the urban infrastructure. The aim of “Klimaflisen” is to use rainwater where it falls. Rainwater therefore is included in a circuit, where the water from roofs and pavements is slowed down, seeped, evaporated, used and diverted.
Despite the name “Klimaflisen”, we are not just talking about a ‘simple’ tile but rather a modular plug & play system, which connects or separates different functions on and below the ground in towns and cities. More specifically, the concept consists of an underground water management system in the form of a dry well (the so-called “plug” part), which is connected to play and recreational areas in urban spaces (the play part).
With “Klimaflisen”, the pavement of the future will be able to collect and manage water and at the same time contribute to for example the greening of cities, providing more and
better public spaces with recreational elements, just as the concept provides the opportunity to conceive new solutions in relation to accessibility and wayfinding. Klimaflisen spaces have great potential With pavements in even the smallest and most dense towns and cities, “Klimaflisen” is a solution with comprehensive potential both in Denmark and in other countries where water management and urban development are a political priority.
There are more than 700 km of pavement in Copenhagen, and over 20,000 km of pavement in New York. As a concept, “Klimaflisen” is easy to modulate and scale in relation to local
requirements for water management, and at the same time it provides new possibilities to create more value in towns and cities.

An urban space and a climate change adaptation solution

“Vandvejen” (Waterway) combines water management and good architecture in a single system solution, re-thinking roads as part of the adaptation to climate change in densely built-up areas.
With increasing rainfall and demand for attractive and healthy urban spaces, there is a need to activate the densely built-up town and city in new ways. “Vandvejen” re-creates the town
and city’s basic elements as more than a transport system. “Vandvejen” is a robust solution for managing rainwater and an option for creating an attractive urban space, where diverse user groups benefit.
“Vandvejen” consists of two basic parts: a road profile that transports the water, and a “Blue Box”, which receives the water. The “Blue Box” is the water management element, which can deal with ordinary rainfall up to the desired service level, for example 5 or 10 year annual rainfall, while the road’s profile ensures that the system also has the necessary extra capacity to deal with extreme events. The profile efficiently diverts the water away from paved areas and building facades and the risk of water entering cellars etc., is eliminated. 
“Vandvejen’s” system structure takes the entire street space into consideration during the design process. By considering the street as more than a conveyor and instead thinking of the road as a location, we can create an attractive urban space, which satisfies the needs of diverse user groups without compromising the safety of road users. 
In densely built-up cities, there is a need to supplement the drainage system with sustainable urban drainage solutions if adaptation to climate change is to succeed. The problem is not just one of increasing volumes of water. In towns and cities, the new climate adaptation solutions are primarily and expression of the acceleration in the number of runoff areas that have been created in the last century. Just in Copenhagen, the run-off percentage is now at around 80 %. If major damage is to be avoided in densely populated urban areas, it is necessary to find new ways of managing the water and which also actively involves the citizens in climate change adaptation.
“Vandvejen” ensures that there is both water and attractive new urban spaces. All of this together, without comprising the road’s functional legitimacy as a conveyor of users moving at different speeds.
