WeSenseIt: The Delfland Case Study

The surface water system in and around the city of Delft, the Netherlands, faces excess water several times a year during intensive rainfall events, in exceptional cases resulting in flooding. The general public, industry and farmers in the Delfland region are affected locally by water in cellars, on the streets, in greenhouses, and on the fields. In dry summer months they are affected by water quality problems through salinization and eutrophication. The Delfland water authority needs to gather more real-time information on the state of the water system than it currently receives from the in-situ monitoring network.

41,000 Hectares highly industrialised testing ground
The Delfland area also includes the world famous Westland region which is almost fully covered with greenhouses producing a significant portion of the nation’s agricultural needs as well as high-level agricultural products for export. All regional stakeholders need more timely and local warnings for short-term event management, and more and easier exchange of information about the operation of the water system for developing and deciding on long-term policies.

Digital Delfland
The Delfland regional water authority has therefore developed a new policy – Digital Delfland, part of the Dutch national Digital Delta program – in which they point out the 41,000 hectares highly industrialised and highly controlled Delfland region as testing ground for monitoring and feedback experiments. The current extensive hardware-based monitoring network of the Delfland water authority, which presents information on precipitation, water quality, water levels, pump operation and system performance, can be used for these experiments,

WeSenseIt is the first Digital Delfland project providing monitoring information for all, including citizen information.
