As our cities grow, increased rainfall is becoming a bigger problem - putting pressure on both infrastructure and health. In the near future, cities will experience problems with flooding, issues with water quality, stormwater runoff, and damage to buildings, infrastructure, and ecosystems. Furthermore, extreme weather can create major local challenges with flooding and potential environmental problems if sewers are overloaded. These are just some of the severe consequences caused by heavy precipitation that, according to scientists, will continue to impact the future climate.

To ensure that sewer systems in cities do not overflow in the case of a cloudburst and cause severe problems in the urban space, stormwater management will become an inevitable part of the future cityscape. At Milford we work with nature, and one of our core services is providing innovative solutions for stormwater management.

Why use Aquaton? 

As stormwater management becomes an inevitable part of the future, questions on how best to tackle severe consequences caused by heavy precipitations are ever-present.

This is where Aquaton (DK, SE) comes in. Our Aquaton Stormwater Management Chambers are an important solution which helps tackle today’s pressing problems with increasingly extreme rain events. Aquaton can be used as underground retention chambers, for rainwater harvesting, and for local infiltration. As such, Aquaton captures the runoff as close to the source as possible. Furthermore, Aquaton can help handling problems that arise with “First Flush”, which means that there will be a higher concentration of sediment with pollutants in a large rain shower after a dryer period. It is important, after this, to collect and filter these pollutants from the water. By filtering and capturing the stormwater, Aquaton can thereby improve the water quality and reduce the water quantity.    

Below is a list of our most successful projects and the LAR challenges that we overcame.

Trongårdsparken–A Climate-Adapted and Recreational Area

The challenge with our project for Tronsgårdsparken (DK, SE) was how to incorporate stormwater management while not compromising the liveability of urban spaces.

The drinking water in Trongårdsparken, which is situated in the Danish town Kongens-Lyngby, is collected underground. To secure the new residential housing area against flooding, which can potentially impact the local drinking water, it has been crucial to make Tronsgårdsparken more resistant to heavy rains. Heavy rain doesn’t only cause problems with flooding in basements and low-lying areas, but a sudden flood can also overflood sewer systems and risks wastewater reaching the surface.  

Tronsgårdsparken is a successful example of a climate-adapted area that can now withstand a future with more heavy rains and that – at the same time – gives life to the neighbourhood.

By establishing the stormwater management system underground in rain beds, the solutions are hidden away in the form of green spaces that can be enjoyed by the people of Tronsgårdsparken. In addition to the area now being climate-adapted, the residents also come closer to nature, which increases their well-being.

The new green spaces and common areas now stimulate biodiversity and give more life to the neighbourhood, inviting the residents to spend time together.

Horsedammen — A Dynamic Public Car Park    

Horsedammen (DK, SE) was a challenging yet exciting climate project for Milford — our team used innovative solutions to ensure Brøndby Municipality’s climate adaption plan could be executed.  

Horsedammen’s detached housing estate was hit hard by flooding during major rain events. Put forth by Brøndby Municipality’s climate adaption plan, the parking area was set to act as a basin for delaying rainwater. In order to meet the service requirements, the basin must be able to accommodate 2000 m3 of rainwater. This was made more difficult by a high-altitude groundwater table, a nearby groundwater drilling, as well as a high overflow to the rest of the rainwater pipes. This meant that the basin had to be established with a low structure as well as have a fixed bottom to avoid road salt from seeping.

The requirements were met by installing our Aquaton stormwater management chambers. The basin was built up of 18 rows of chambers which had the capacity of 2000 m3. In addition, 1000 m3 was added to the parking area itself, which was submerged and established with permeable asphalt pavement. The underground rainwater basin was enclosed by a bentonite membrane to avoid seepage.  

In addition to this, the operation of the new basin was of great importance to the design. The accumulation of sediments in the basin meant there would be less volume and, as such, a deterioration in its function. Milford’s project team successfully developed a new technical solution that made the basin network much more reliable, accessible, as well as increasing the life expectancy from 30 to 75 years for a relatively small additional cost. The new solution consists of connecting the basin to a large concrete sand trap, designed to lower the water velocity to reduce sediment in the basin.

Östra Sala Backe—A New Green District

Östra Sala Backe (DK, SE) is an up-and-coming green district in Uppsala, Sweden—with new parks, squares, and a vibrant urban centre. In connection with these new developments, future-proofed solutions for handling rainwater needed to be implemented. With the new district, the proportion of impermeable surfaces has increased. Considering major cloudbursts, this posed challenges to the district.

With Milford’s innovative approach, rainwater has successfully been integrated as a resource for watering the vegetation and trees in the new rain beds, whilst our Aquaton stormwater chambers act as an underground infiltration basin in case of major rain events.  

Snättringe, Stockholm–Football Fields

Sports fields are often large, open, and green areas. They are, therefore, highly efficient in handling and collecting stormwater and can handle stormwater from the sports field itself and the surrounding areas.  

To put it simply, during a heavy precipitation event on Snättringe football field, the stormwater is now collected from the field in our Aquaton stormwater management chambers underground. This way the field can be used both during and after major precipitation events, where the stormwater is either used for local infiltration or can be redirected towards the sewer system or other SUDS-systems.

Our project to create a multifunctional football project in Snättringe, was a success in terms of creating an underground stormwater management system. The football field was fully transformed by the end of 2021 with the Aquaton chambers having a capacity of containing up to 1600 m3 stormwater.
