Heavy rain and snowfall easily overburden drainage and sewer networks in cities. A new solution is helping municipalities to prevent water damage.
It may not be something we frequently consider, but disruptions to the sewer network can create major problems in any large city. ICT plays a key role in the management of this, often invisible, infrastructure. Fujitsu has developed a new technology which is capable, at a very low cost, of alerting to the risk of the system becoming overburdened due to heavy precipitation. The early warning will help prevent damage in many urban areas when significant rain or snowfall is experienced suddenly.
Many cities have fallen victim to damage caused by precipitation in recent years. The focus is increasingly placed on ICT solutions to improve how these situations are managed. For instance, water levels in manholes can be monitored in real time, allowing administrators sufficient time to take action. However, this is where the operation hits a wall, with high costs for installation and maintenance of a comprehensive network of sensors and other equipment representing a hindrance.
From the continuous need for replacement batteries to the costs for the many sensors, circuits, and wireless connections: until now, an ICT system of this sort proved far too expensive. However, Fujitsu Laboratories now offers a real solution in a newly developed technology. This technology calculates precisely where, and in how many locations sensors are actually required. This is based on an analysis of the time taken for the water to flow from one place to another, taking into account the design of the sewers and the characteristics of the terrain.
The result of the new technology developed by Fujitsu Laboratories is that only a fifth of the number of sensors are now required. But that’s not the only thing. Fujitsu Laboratories also developed a technology that performs calculations more efficiently, as well as a connected technology capable of reducing energy consumption by around 70%. All of this, without impacting on precision. This makes it possible to utilize solar or other renewable energy sources. Operational costs of an ICT system that combats the risk of flooding are easily 90 percent lower than before.
