Retention capacity

Saving drinking water

Spangen, a neighbourhood located in the west of Rotterdam, is vulnerable to pluvial flooding during heavy precipitation events due to a lack of retention capacity. At the other hand, the Sparta Stadium, located in the neighbourhood, uses a significant amount of water for the irrigation of the sport fields.

We are working together with the Municipality of Rotterdam, Waterboard Delfland, Evides Water Company, KWR Watercycle Institute and BE-de Lier, on a pilot project to implement underground rainwater storage and recovery.

The aim of the project is to collect, filter, and infiltrate rainwater in the underground to solve the need for retention capacity in the neighbourhood; and to use the stored water to provide the Sparta Stadium with a decentralised source for irrigation.

__Identify

Exploring the possibilities.

A feasibility study has been executed, to explore the possibilities to integrate the system in the surrounding and to define the technical criteria for the design of the system. The starting point of the study has been the accommodation and spatial integration of the different functions of the system, including pre-treatment, water storage, and installations, without conflicting with the existing spatial functions, such as routing, parking, and green. The goal has been to integrate the system in such a way that it contributes to the enhancement of the surrounding.

Adding green and spatial quality, while making Spangen water resilient.
— How might we create value

__Design

Defining the technical criteria, drafting the spatial implementation

Based on the spatial possibilities, a technical design of the system with the associated technical specifications has been executed.

__Develop

In close collaboration with designers and urban managers of the Municipality of Rotterdam, a definitive design for the square around the Sparta Stadium is currently being executed, integrating the functions of the UWB system, while giving the neighbourhood a pleasant public space.

 

__Implement

The implementation of the project is expected to be executed by the beginning of 2018.
