Urban water management in Tilburg

As part of the Spatial Adaptation Delta Programme, climate stress tests will be performed all around the Netherlands to better prepare the country for climate change. For the municipal authority of Tilburg, Witteveen+Bos is conducting a detailed assessment of the flooding risks for the entire city.

The main effects of climate change are: more heavy rainfall as well as global warming and longer periods of drought. For this reason it is important to investigate the best approaches to water management and flood protection. Tilburg municipal authority is a front runner in terms of climate adaptation.

As part of the risk assessment we will calculate the water flow through sewer systems and in surface water, and the run-off across the streets. Subsequently, we will assess the consequences of flooding: how it will affect residents (e.g. flooded homes), businesses, public buildings and traffic. This risk assessment is required to determine the need for measures. We will focus on the most sensitive locations.

Tilburg municipal authority has already put in place a number of measures to make their sewer system more robust. The new measures mainly focus on redesigning public spaces. Think of controlled discharge of water via the road profile or use of public greenery for temporary water storage. The measures will be selected in consultation with the municipal authority and the water authorities, taking account not only of flooding but also of how the measures will affect the other aspects of climate change.

We will ultimately define a set of possible measures which the municipality can use to incorporate climate adaptation in redevelopment projects all over the city, rather than only in the most sensitive areas.
