Abstract:The morphology of the terrain of Enschede is a hill, together with impermeable soil and paving this results in regular floods as a consequence of heavy rainfall. The municipality of Enschede is looking for a solution to be implemented on the premises of the inhabitants of the most affected areas. The aim of the system is to buffer up to 7000 m³ for the whole affected area; it is to be implemented within the property of the inhabitants. In this thesis, a solution to the problem is proposed: A Smart Rainwater Buffer. This solution uses the principles of hollow fences to create a buffer in which rainwater is stored during heavy downpour. The stored water can be used to water the garden, and is released via a weather-aware smart valve in response to buffer capacity and expected rainfall. The system can be monitored with a webpage that automatically updates in response to changes to the system. A total of four prototypes were presented to the municipality of Enschede and the regional waterboard Vechtstromen. The result is an intelligent weather-aware buffering system that empties itself before heavy rainfall, which is installed in the garden of house owners. In order to improve the prototype, long-term testing is required to assess system performance and stability over periods of time. In conclusion, a functioning prototype was developed and tested, which if implemented by 3500 households could effectively buffer the required 7000 m3 of rainwater.
