WeSenseIt is an EU FP7 project developing citizen observatories of water and flooding to facilitate citizen engagement in planning, decision making and governance. One of the three case studies within the WeSenseIt project is the Dutch Delfland Case.

Delfland Case: 41,000 hectares highly industrialised testing ground

On an area of 41,000 hectares, about 1.4 million people live and work, and approximately 40,000 businesses are established. This makes the Delfland region one of the most densely populated and most highly industrialized areas of the Netherlands. The region is furthermore renowned for its intensive glasshouse horticulture.


The WeSenseIt Delfland Case focuses on crowdsourcing approaches to enhance the information chain of water authorities and the general public. Information sources of professionals and the public are enhanced, shared and blended to new, more detailed and localised information. This supports water managers to better perform their tasks and stimulates the public to be better informed and engaged in water management.

The project delivers new smartphone crowdsourcing apps, innovative low cost Disdro rain gauges, and autonomous soil-moisture sensors. It encouragescitizen communities to upload, share, discuss and rate data and information on their water environment with a focus on minimising the effects of pluvial flooding and poor water quality.
