METAWATER's first industrial water management system

METAWATER Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; President: Yasushi Nakamura; hereinafter referred to as "METAWATER") is pleased to announce that it completed constructing a water management system for rebuilding the industrial water supply network ordered by the Oita Prefecture Company Station, in March 2017 and has started operating the system.

The Oita Prefecture Company Station supplies industrial water to the Oita Complex via three water supply routes after treating raw water taken from the Ono River. However, there is a risk that accidents in these water supply routes may suspend the supply of industrial water, known as the blood of industry. Prolonged interruption of water supply may cause significant economic losses. In order to address this issue, the Oita Prefecture Company Station has rebuilt the water supply network which mutually supplements the three water supply routes.

METAWATER's newly developed water management system has been introduced with the aim of taking a detour in case of an accident in the water supply routes in order to ensure continued supply of water in an appropriate water volume and pressure. In addition, the system is designed to support operation through simulation. The water operation server for simulation has introduced InfoWorks WS and IWLive System* providing real-time pipeline network analysis, both of which are provided by EMORI Infotech Co., Ltd. (formerly, Information Section of EMORI & CO., LTD.; President: Noboru Yamamoto, Headquarters: Fukui-shi, Fukui), for the first time in the water business field in Japan. The server has made it possible to achieve the measured value and target control value by establishing a link with a plant simulation system.

This is the first time METAWATER has provided the water management system for industrial water supply networks. METAWATER will contribute to supplying industrial water that supports the local economy by leveraging its extensive expertise in the development of monitoring and control systems as well as water operation systems in the water business field.

* InfoWorks WS and IWLive System: InfoWorks WS is capable of performing dynamic simulations of water supply networks. The tool has been developed with the aim of analyzing performance of water supply networks from various angles to support planning and maintenance of water supply. IWLive is a higher-order system of InfoWorks WS and a system to predict water pressure and flow rate by providing real-time observation and control data to a water supply network model developed by InfoWorks WS. The system supports monitoring and optimization of facilities in a normal situation while analyzing and verifying countermeasures including recovery plans in advance in an emergency situation in addition to instantly calculating the current situation.

　system (existing facilities), plant simulation system, and water operation server
9) Purpose of system development：

• Developing a water management system enabling integrated management of facilities consisting
  of a water supply network by installing booster pumps and bypass valves that can be monitored
  and controlled remotely.
• Ensuring continued water supply to customers via different routes by instantly conducting simulations in
  case of an accident in water supply routes and coordinating with plant simulators.
  Providing support for operators' preparation by conducting scenario analysis in advance in preparation 　　for
  accidents and succession of technologies.
