Developing a Framework to Appropriately Prepare for Serious Damages Due to Heavy Rain

Heavy Rain Sewage Management System jointly developed with the city of Tomakomai

The Sewerage Department Planning Section at the Tomakomai City Water and Sewerage Department handles a wide range of tasks including improvement projects for daily maintenance and management of the sewerage services, to medium and long-term improvement projects.

With damage from torrential rains growing ever more serious in recent years, we worked with the city to develop the Heavy Rain Sewage Management System with the general-purpose cloud basin disaster prevention information OS RisKma at its core. This framework was designed to collect information on heavy rain and its effects more quickly and efficiently to facilitate the development of proper countermeasures.

The system makes it possible to gather rainfall information and grasp its effects on sewerage facilities in real time and streamline patrols by local government staffers, significantly lightening administrative burdens.

The Heavy Rain Sewage Management System with our general-purpose cloud basin disaster prevention information OS RisKma at its core was jointly developed and introduced with the city of Tomakomai to deal with a lack of technical staffers due to a dwindling birth rate and aging society, and serious damages due to heavy rain. It has been praised for streamlining tasks and lightening the workload of city staffers, winning the 15th Minister of Land, Infrastructure, Transport and Tourism Award (Junkan no michi Sewage System Award) in the Asset Management Division.
