Metawater Technology Selected for B-DASH Project
- “Energy Management System using an Intensive Solid-liquid Separation Technology” -


A demonstration study will be conducted on innovative technology for strengthening regional disaster prevention capacity in cooperation with residents as part of comprehensive structural and nonstructural flood control efforts.

METAWATER Co., Ltd. (Headquarters: Tokyo, Japan; President: Tomoyasu Kida; "METAWATER") is pleased to announce that a "Demonstration Project: Stormwater Management Technology for Local Heavy rainfall in Urban Area" proposed by a joint study team formed by eight entities, including METAWATER, has been approved for inclusion in the Breakthrough by Dynamic Approach in Sewage High Technology Project (B-DASH Project)* implemented by MLIT. The Demonstration Project will be among the projects to be implemented in 2015.

Fukui City and Toyama City have been selected as the two fields for the project designed to verify various aspects of a system of measures proposed to improve the collection and accuracy of rainfall data, to confirm the extent to which the measures can be applied, and to find ways to promote expanded use of the system.

* A demonstration project implemented by MLIT since 2011 to support the development of overseas water business by improving the efficiency of energy utilization in wastewater systems and reducing stock LCC by accelerating research and development work and practical implementation of new technologies. This project consists of demonstrating the effects of innovative technologies proposed by entities selected by public invitation and examined by experts. Plants of actual scale are used in the demonstrations.

Roles of members of the joint study team and targeted demonstration effects
Fukui City and Toyama City: Provide fields for the study
Kobe University: Provide rainfall prediction technology
Furuno Electric Co., Ltd.: Build radar system
Emori: Provide runoff analysis software
Shinnihon Consultants, Nihon Suido Consultants: Establish simulation model
METAWATEWR: Provide overall coordination using multidisciplinary engineering
Goals of the demonstration
To promote self-help and mutual help and a higher level of facilities operation based on real-time rainfall information and rainfall prediction information by means of a radar system

This project is designed to show the effectiveness of a combination of three innovative technologies developed to mitigate flood damage from local heavy rainfall events, which have recently been increasing in frequency and often exceed stormwater drainage capacity, by maximizing effective utilization of the functions of existing stormwater control facilities, by preparing and distributing flood hazard maps, and by ensuring sufficient time for self-help and cooperation among residents.

The joint study team consists of eight members: Fukui City (Mayor: Shinichi Higashimura), Toyama City (Mayor: Masashi Mori), Kobe University (President: Hideki Fukuda; Administrative Office in Kobe City, Hyogo), Furuno Electric Co., Ltd. (President: Yukio Furuno, Main office in Nishinomiya City, Hyogo; "Furuno Electric"), Emori Co., Ltd. (President: Kiyotaka Emori, Main office in Fukui City, Fukui; "Emori"), Shinnihonn Consultants (President: Tomoaki Ichimura, Main office in Toyama City, Toyama), Nihon Suido Consultants Co., Ltd. (President: Kiichi Nomura, Main office in Shinjuku-ku, Tokyo; "Nissuikon"), and METWATER.

Outline of the demonstration project

Conventional rainfall projection and observation systems have been unable to provide enough information to secure time for organizing self-help and mutual aid activity. Correct rainfall prediction and information on discharge points are available only in a limited manner at stormwater storage facilities. Consequentially, operations are often handled without sufficient control, resulting in failure to effectively utilize facility capacity. Fukui City and Toyama City had carried out structural development to cope with local heavy rain events occurring approximately once every five years. However, floods caused by local heavy rainfall have been occurring more frequently in recent years, which makes new approaches to flood control necessary, including nonstructural measures such as developing highly-accurate rainfall observation and flood prediction systems.

The project involves (1) early detection of cumulonimbus with an "urban-area small high-resolution multi-radar system ("urban-area radar system"*); (2) prediction of rainfall amounts and intensity with a "short-term rainfall prediction model"; and (3) prediction of flood areas with a "real-time fast storm water runoff prediction and analysis system ("fast runoff analysis system)." The project is intended to demonstrate that these technologies, when applied rapidly and accurately, offer the benefit of damage mitigation by promoting self-help and mutual assistance among residents, including placement of sandbags, evacuation to high ground or hills, and by ensuring maximum utilization of the functions of storm water drainage facilities by providing support information to these facilities.
