Creating rainwater management solutions that detain the water in existing structures or distribute it to areas where it creates the least damage
Increasing precipitation caused by climate change is putting great pressure on cities’ sewerage systems. A way to increase capacity of the sewerage systems can be to focus on rainwater management solutions that detain the water in existing structures or distribute it to areas where it creates the least damage. In Denmark, we are increasingly using hydraulic models in the planning phase and implementing solutions for local rainwater retention, including subsurface infiltration beds, green roofs and permeable paving. This makes it possible to alleviate the pressure on the traditional sewerage system and bring down the risk of combined sewer overflows. Other solutions include the use of separate sewers for rain and sewage water and treating rainwater locally via roadside infiltration beds and sand traps, .
We invite you to explore solutions related to rainwater management in more depth below, find potential partners, catch up on the latest related news and discover real-life case examples of how rainwater management can help solve your environmental challenges.

Architecture can reduce the climate footprint and protect buildings and urban areas against climate change. Climate change calls for stronger initiatives in the building and construction sector – both to promote broader use of sustainable solutions and to make our buildings and cities more resilient to climate change.
The climate is changing: how do we manage extreme rainfall? Not only more rain is falling due to climate change, but rain showers are often more extreme. This means that a lot more water has to be collected and disposed of in a short time. In the countryside this is not usually a problem, but it is more so in the increasingly urbanised environment.
Gottlieb Paludan Architects has designed Solrødgård Climate and Environmental Park, which is the result of an unusual symbiosis between supply plant, climate adaption and landscape park. The aim of the park is to let visitors explore energy cycles which are fundamental to daily life.
Five Danish cities feature in the 2019 Cities 100 report, a publication which shines the spotlight on 100 of the most forward-thinking and inclusive climate action projects worldwide. The projects demonstrate how the cities are working toward fulfilling the Paris Agreement and solving the climate crisis.
The next application round for P4G funding to partnerships with a sustainable business model is open. Funding of between USD 100,000 to USD 1,000,000 is available to either partnerships with a start-up or a scale-up concept.
Over the last 39 years, the cost of extreme weather and climate events in Europe has been EUR 453 billion. Compared to the number of citizens and land area, Denmark has paid the second highest price. However, it is predicted that the costs in the future will be lower as the country has become better at protecting its values after the cloudburst in Copenhagen, 2011.
City-to-city partnerships have the potential to accelerate climate resilience and innovation. The New York City-Copenhagen (NYC-CPH) partnership is an example of such partnership. Background The partnership between New York and Copenhagen had its early beginnings in 2013 when a CPH delegation visited NYC to look for opportunities for knowledge exchange, partnering and a platform for […]
A unique water treatment plant has seen the light of day. The innovative cleaning technology is the first large-scale attempt to solve the challenges cities face with road runoff that pollute the aquatic environment and groundwater or that has to be pumped all the way through cities to be cleaned at sewage treatment plants.
The harbour contributes to Copenhagen’s reputation as one of the world’s most liveable and sustainable cities. However, this has not always been the case. In 2020, Copenhagen municipality will roll out new green harbour busses as a plank in its efforts to become a CO₂-neutral capital with a sustainable public transportation system.
Klima100 is out today containing a list of 100 of the most innovative climate solutions from local governments across Denmark. The publication provides an in-depth understanding of how Danish municipalities are adapting to climate change, working towards slowing global warming, and creating a greener future.
Our cities are growing and so is the need to make them more sustainable and liveable. In this month’s article, we gather 3 examples of holistic urban solutions from a water and climate adaption perspective that contribute to creating liveable cities.
A new project aims to change the way we manage water cycles in cities. The partners behind the project want to revolutionise the way we understand and manage urban water. The vision is to profit from climate adaptation and to win socioeconomic savings.
Streets constitute a significant share of the total surface area of Danish cities. In terms of elevation they literally form the bottom line. Schulze+Grassov are under contract with Denmark’s Realdania Foundation under the Danish Klimaspring initiative to develop new innovative climate adaptation systems. Working creatively with streets in urban environments we seek to turn a […]
In this paper, you will meet the ten partners behind the Tours Network and find inspiration for site visits across energy efficiency, renewables, waste and resource management, clean air, water and climate adaptation.
If you are interested in visiting Denmark to explore these solutions and learn more about the concrete technologies, as well as connect with Danish stakeholders and share knowledge about green growth development, we encourage you to contact the Tours Network.
As the climate changes and the number and frequency of rainfall events increases, so does the need for intelligent rainwater management solutions. This White Paper presents insight into lessons learned from Danish stakeholders within rainwater management and Sustainable Urban Drainage Systems (SUDS).
In July 2011 Copenhagen experienced the worst rainfall ever with more than 80,000 homes flooded resulting in damages at a cost of around 1 billion €. A new tool has been developed in order to minimize damages from such events in the future. Quick solution to combat effects of climate changes With the climate changes, some […]
Dual Porosity Filtration (DPF) treats contaminated surface water, for instance water from roads, so it can meet high environmental standards. DPF technology treats the water to a high quality without the use of chemicals and holds the potential to transform contaminated surface water into drinking water. How does it work? A dual porosity filter has […]
The Danish portal on Climate Change Adaptation, managed by Danish Nature Agency, presents a range of positions on climate change and climate change adaptation within a number of areas. The site is a collaborative effort with Danish ministries and agencies, targeted at citizens, companies and local authorities. The portal provides up-to-date information and news on […]
An overflow construction, placed at Kærbyholmrende, Middelfart, functions as a test and demo site for cleaning combined sewer overflow (CSO) with a HydroSeparator. The project is a cooperation between Middelfart Wastewater and Bonnerup Consults, and is supported by the Ministry of Environment. The HydroSeparator is developed by Bonnerup Consult primarily for treatment of rainwater, but […]
The HydroSeparator® is a patented system for treatment of storm water and Combined Sewer Overflow (CSO) where local requirements for treatment are strict.
