Abstract:This bachelor thesis describes the process of developing a monitoring and control infrastructure for a smart rainwater buffering ecosystem for the municipality of Enschede. The purpose of the system is to reduce the strain on the sewerage system of the Oldenzaalsestraat in order to combat urban flooding. Literature research, neighbourhood research and interviews with stakeholders led towards the development of a concept: a system of smart rainwater buffers which adapt their performance according to the predicted rainfall and show their data on an interface. Ultimately, the system is supposed to be implemented on the private property of citizens living in the neighbourhoods De Bothoven and Velve-Lindenhof. A prototype of the system was realised using a rainwater barrel, which contained sensors to measure the water level and outflow to the sewerage system, the garden and through a faucet. Furthermore, the barrel contained controllable valves to the sewerage system and garden. When rainfall is predicted for the next 2 hours, the valves are opened to release water and create sufficient capacity for the expected rainwater. The data produced by the rain barrels is presented on two web interfaces. The overall buffer performance can be monitored by the municipality on their interface, while the buffers can be monitored and controlled locally by the citizens on theirs. The prototype of the system was evaluated and the interface for the municipality was tested with representatives of the municipality. The performance of the prototype was not yet accurate and stable enough for long-term implementation. However, the interface was found to fulfill its job.
