SUSS: Smart Drainage Solution
SUSS provides a proactive real time control of urban drainage systems.
Worldwide many regions suffer from more frequent and intense rainfalls. Existing urban drainage systems cannot cope with sudden and large amounts of water, leading to flash flooding. This can have severe consequences: injuries and deaths, damages to roads and buildings, pollution. Expanding existing urban drainage systems or building new ones is too expensive; existing smart urban drainage systems with real-time control suffer from high cost, inflexibility for big data driven control, and are not secure enough. Our solution helps solving this problem. The key idea is to use the existing developed land for accumulating and regulating the excessive flow as effectively as possible by means of cutting-edge technologies: large distributed network of wireless sensors transmitting water information to a control center; sophisticated data analytics, use of weather forecast models, and realtime control strategies decide where and when to open/close the valves and accumulate water on the surface. Network security mechanisms reduce the risk of malicious behavior and decrease fault identification times. A key advantage is that there is no need to rebuild the existing pipelines nor to install cables for a massive sensor system. The installation cost of a permanent urban drainage monitoring station can be reduced by at least 10 times; that of a temporary networked monitoring station can be reduced by 3-5 times; the battery service interval can be extended by at least 20 times. Due to sensor fusion, data driven hydraulic system modeling and control, our solution can reduce the risks associated to flash flooding (up to 50 % less combined sewer overflows activations and up to 50% less peak flows) without major investments. Early warning can be sent to citizens, which improves crisis management and reduces losses. The risk of sewage overflow pollution is reduced by up to 50 % without additional investment into pipeline rehabilitation.
