Abstract:More frequent and heavier causes issues especially in the city of Enschede that is built on a gentle slope where rainwater will runoff, causing damage in the city centre. The sewerage system of Enschede is not built to handle this amount of rainwater. Therefore, the municipality of Enschede is looking for a solution to reduce the strain on the sewerage system; a smart rainwater buffer meant for implementation on the private properties of the inhabitants of Enschede. The smart rainwater buffering system, Tonnie, consists of a smart buffer, a database and an interface. The smart buffer has several components including two solenoid valves for automatic and manual discharge towards the sewerage system or the garden, a faucet for tapping water, five flow sensors to measure in- and outgoing flows and an ultrasonic sensor to measure the water level inside the buffer. The interface has been programmed with JavaScript and contains almost all the user interaction with the system. By using this interface, citizens are able to select valves, set an amount of water that the system should discharge and open the valves. Furthermore, the buffer’s performance is visualised including the current capacity, future catchment data, history data and precipitation data.
