Solutions for urban climate adaptation in practice

The stories behind our projects

The Netherlands as a water country

The Netherlands and water are inextricably linked. Its inhabitants have been dealing with water for more than 1000 years, which is why the Netherlands has become the supreme water management country.

A large part of the land was reclaimed from the sea and has since been protected from it by dikes and barrages. For example, the legendary Delta Works in the province of Zeeland, which consist of a total of 13 structures, form the world's largest storm surge barrier and protect the interior of the country from high water and flooding.

The mills, pumping stations, polders and dikes are world famous and have made the Netherlands what it is today.

Using this centuries-old knowledge, we at Rockflow have developed new techniques, and have already implemented these in hundreds of projects in the Netherlands.

Our case studies

Get to know our urban climate adaptation solution through the stories behind a number of projects where Rockflow has been applied. These articles explain what the situation was on site, why Rockflow was chosen and how partners experienced the realisation of the Rockflow system:

Rockflow project Amsterdam Nieuwe Zijde noord

Solution: Linear attenuation and drainage system

Amsterdam: Riding over the Rockflow infiltration system by tram

In the redevelopment of Amsterdam's Nieuwezijds Voorburgwal, climate-adaptive measures were implemented, including the construction of a Rockflow water storage and infiltration system.

Solution: Swale

Infiltrating and retaining water under a 'climate bioswale' in Zoeterwoude

Rockflow is used in more and more cities in the context of climate adaptation to prevent flooding. The system can also retain rainwater as a buffer for drier periods. These two functions - infiltration and retention - were recently combined in a single system for the first time. Thanks to a request from Zoeterwoude.

Rockflow - central buffer - Amsterdam Noord

Solution: Central attenuation and drainage system

Rockflow helps achieve Amsterdam Rainproof ambition

The Dutch capital Amsterdam is working hard on water management. The project Amsterdam Rainproof aims at making Amsterdam resistant to increasingly frequent downpours. Rockflow as a water management solution is applied in various projects in Amsterdam and becoming an integral part of Amsterdam's toolkit for urban climate adaptation.

Rockflow - Groessen - Stedelijke klimaatadaptatie

Solution: Linear attenuation and drainage system

Infiltrating rainwater with Rockflow in Groessen

The Municipality of Groessen chooses Rockflow as a flexible, sustainable solution for a high groundwater level, heavy showers and longer droughts.

Rockflow Infra - Eindhoven - Hastelweg - Stedelijke klimaatadaptatie - Case

Solution: Linear attenuation and drainage system

Adapting to the climate in Eindhoven: there's also innovation below the ground

The Municipality of Eindhoven has opted for a stone wool water buffer system in the city center as a solution to flooding. Rockflow collects and gradually discharges rainwater into the soil.

Rockflow - Beverwijk - Brink - Case - Stedelijke klimaatadaptatie

Solution: Central attenuation and drainage system

Climate adaptation for Beverwijk apartment complex with Rockflow

In Beverwijk, the Netherlands, a new construction project is not allowed to discharge rainwater via the sewer system. The apartment building with 94 sustainable, gasless homes will therefore be equipped with a Rockflow central attenuation system under the building and a water-buffering roof with stone wool elements under a sedum cover.

Solution: Central attenuation and drainage system

Horst aan de Maas: climate adaptation key to local development

The area around the cultural center 't Gasthoês in Horst aan de Maas, which is being renovated, is being redeveloped into a green area. This hard surfaced area is faced with the problems of heavy downpours, extreme drought and heat stress. The Rockflow infiltration attenuation and drainage system has been used in this area. The fully recyclable infiltration system ensures that local flooding on paved surfaces surrounding ‘t Gasthoês is reduced.

Rockflow offers a solution for the playing field in Heel

The playing field in Heel was located in a groundwater protection area, which presented a lot of challenges. Rockflow offered the solution here because a lot of storage can be created while you remain fairly close to ground level.

Amsterdam becomes rainproof with Rockflow

Platform 'Amsterdam Rainproof' has the aim of making Amsterdam resistant to the increasingly frequent downpours. The sustainable solution Rockflow helps Amsterdam to combat flooded streets and basements due to intense rainfall.

rockflow water management den haag paschalis school before after buffer infiltration project

Solution: Central attenuation and drainage system

From a concrete school ground into a green-blue playground with Rockflow

The Rockflow central attenuation and drainage system is a practical and sustainable solution for the primary school Paschalis for the heat stress and flooding problems that the schoolyard had to deal with. The result: a square with lots of greenery that challenges all age groups to sport and play activities.

Solution: Linear attenuation and drainage system

Maasbracht also opts for the Rockflow infiltration system in a residential area

A Rockflow water storage and infiltration system is applied in the municipality of Maasgouw (Limburg) under residential streets as a rainwater sewer. The municipality had previously successfully installed the Rockflow buffer system under playgrounds and parking lots.

lapinus, rockflow, water management, case study, Hedemora, Zweden, Sweden

Solution: Central attenuation and drainage system

Hedemora installed Sweden’s first Rockflow rainwater buffer

Sweden also suffers with increasingly extreme rainfall in the summer. Hedemora, a town in a hilly landscape where rainwater has always found a natural way, is the first municipality in Sweden where the increasing flooding is counteracted with a Rockflow rainwater buffer.

Solution: Central attenuation and drainage system

Rockflow under schoolyard 'Kirkeveldsje'

Flooding occurs everywhere, including in schoolyards. In Schimmert, the problems with flooding in the schoolyard of the 'Kirkeveldsje' have been solved by applying Rockflow.

water management, sterplein, case, rockflow, heel, swale, lapinus

Solution: Swale

Rockflow offers a solution for swales in Sterplein

Rockflow tackled a too deep, too steep and difficult to maintain swale in Heel. Water that does not infiltrate quickly enough is led via the gully directly to the buffer from where it infiltrates into the subsoil.

Rockflow improves the built environment in Oirsbeek

Located in Limburg (NL), the village of Oirsbeek in the municipality of Schinnen is vulnerable to flooding due to large amounts of rainwater coming down from the steep slopes that surround it.

Urban renovation Zevenaar sees flood reducing results

An enormous 'sponge' has been installed in Zevenaar for the large-scale urban renewal: the Rockflow water management system. This underground system collects rainwater and slowly returns it to the environment.

Solution: Swale

Rockflow used in shallow swales at Duiven

New district Westreenen in Loo in the municipality of Duiven has been struggling with swales that are too deep and difficult to maintain for some time. With the Rockflow water buffer system, the swales have been redesigned and deepened, turning the deep ditch into a beautiful and safe green strip.
