Monitoring and control systems play a role in the daily operation and maintenance of water supply and sewerage facilities. Moreover, the practice of working through the sense–think–act cycle is helping to pursue digital innovations that will contribute to the sustainability of the water supply and sewerage industry.

The sense, think, act cycle involves using systems that gather (“sense”) operational technology information, analyze the collected data from multiple perspectives (“think”) using artificial intelligence or statistical analysis technologies, and then plan, upgrade infrastructure, and make improvements (“act”) using the acquired knowledge. This makes it essential to provide an infrastructure that can connect the monitoring and control systems to an Internet of Things platform, and make effective use of the operational technology information the systems hold. Hitachi has developed an Internet of Things gateway that makes this possible.

It is anticipated that the sensing of data that could not be gathered in the past and collecting them for use on the Internet of Things platform will help create new value. Work is proceeding on a sensing initiative involving optical fiber sensing that overcomes the power supply challenge and can collect data from inside sewage pipes, as well as image analysis and voice recognition.
