I want to know the adoption record of Yakumo Suishin.

Nationwide Adoption Record

As of March 2025, Yakumo Suishin has been adopted by 516 municipalities and 19,100 facilities.

Adoption Fields

The fields in which it has been adopted are as follows:

• Water supply, simplified water supply
• Sewerage (public sewage, agricultural community drainage)
• Agricultural water
• Industrial water
• Snow removal facilities
• Gates (sluice gates)
• Water level monitoring of rivers and reservoirs

Introduction Examples

Hyogo Prefecture, Taka Town

Remote monitoring of all water and sewage facilities. Guiding accident response from remote locations.

1. happygate Monban Suishin was introduced at 19 water supply facilities and 92 sewage facilities.
2. We can check the situation of the site from our home computer on holidays and at night, which is very helpful.
3. Since a dedicated line is not required, the facility monitoring cost for water and sewage has been reduced by approximately 5 million yen per year.

When the town officials were engaged in emergency water supply activities in Ofunato City, Iwate Prefecture, as part of the support activities for the Great East Japan Earthquake, the turbidity of the town’s water source rapidly increased due to heavy rain. After checking the situation from a mobile terminal 750km away, they guided the response by phone and checked the situation again. They were able to get through it safely, which was very helpful.

Tokyo, Machida City

Overcoming planned power outages through remote operation. The necessity of dealing with long power outages as well.

1. Since 2001, 35 manhole pump control panels capable of remote monitoring and control have been installed in the city hall.

In the city, planned power outages of approximately 3 hours each were implemented 7 times due to the Great East Japan Earthquake. However, leaflets were distributed to residents asking them to refrain from using water during the planned power outage hours, and measures were taken to remotely control the facilities with high inflow volume using computers in the city hall during the planned power outage hours, pre-pressurizing the sewage in the manhole tank, so no overflow occurred.

Shimane Prefecture, Hamada City

Water supply, simplified water supply, and industrial water. Centralized management of 182 facilities.

1. In October 2005, due to the merger of 5 cities and villages, all 182 facilities, including 83 water supply facilities, 92 simplified water supply facilities, and 7 industrial water supply facilities, have been centrally managed by Yakumo Suishin G series at the Mikawa Water Treatment Plant since April 2012.
2. The fact that we can check the facility status and perform remote operations on iPads, etc., even while moving to the site is very efficient.
3. It can be installed on existing equipment, and switching to wireless has led to significant cost reductions.

With the retirement of veteran staff, it is necessary to establish an appropriate management system, especially for simplified water supply facilities, and we have high expectations for the Yakumo Suishin G series. (Water and Sewerage Newspaper, January 1, 2013)

Kyoto Prefecture, Yosano Town

Remote monitoring of all water and sewage facilities. Guiding accident response from remote locations.

1. Yosano Town was born in March 2006 through the merger of the three towns of Kaya, Iwataki, and Nodagawa.
2. happygate Monban was introduced in a total of 59 facilities, including 56 sewage facilities and 3 water supply facilities, and remote operation and monitoring were effectively utilized, leading to a reduction in the burden on staff.
3. Considering the risk of communication failures and connection failures during disasters, a dual data communication system using both web and telemetry methods was adopted, and the system configuration was possible thanks to the cloud-based “Yakumo Suishin,” which was highly evaluated.

Niigata Prefecture, Shibata City

Drainage pump stations, gates (sluice gates), snow melting pipes. Quick response to sudden events.

1. It has been introduced in 148 sewage facilities, 6 gate facilities, and 59 snow melting facilities, and is evaluated as “leading to quick response in the event of sudden events such as equipment failures and sudden changes in weather.”
2. In emergency response, when the water level in the city is expected to rise due to heavy rain, the response of adjusting the gates in advance and guiding rainwater to drainage channels and drainage pump stations becomes quicker and more reliable.

In the city, visual inspections are also conducted simultaneously with the system, confirming that remote operation of the facilities is being carried out reliably, which leads to trust in the system. (Japan Water and Sewerage Newspaper, February 25, 2013)

Fukuoka Prefecture, Nogata City

Adopted in basin-related manhole pump facilities. Ensuring fairness through a comprehensive evaluation method.

1. The Nogata City Water and Sewerage Department conducted presentations by 4 companies to introduce a better system at a low cost when ordering electrical equipment for manhole pumps, and selected Komatsu Electric Industry Co., Ltd.’s product “Yakumo Suishin Manhole Pump Control Panel.”
2. “Initially, we were only considering construction costs, but since initial costs and running costs vary depending on the communication method, we re-examined the selection method to include these factors.

In addition, in order to unify the control panel models and describe them in the special specifications, we decided to hold a presentation to select the models in a public forum, bid, and place the order.” (Water and Sewerage Newspaper, July 20, 2006)

Tottori Prefecture, Misasa Town

Managing water and hot spring facilities. Evaluating reliability and introduction costs, etc.

1. Previously, the central monitoring system using telemetry in the town hall was used to remotely monitor water facilities, etc.
   • However, approximately 30 years had passed since its installation, and there were issues such as frequent failures due to aging and running out of stock of replacement parts and consumables.
2. From around 2008, the town considered updating the device for remotely monitoring both water supply and hot spring facilities, and implemented a designated-type proposal requesting technical proposals in order to select a method that was superior in terms of costs and technology and did not lead to a decline in resident services.

The selection was based on the technical aspects of the monitoring method, the introduction and maintenance costs, etc., with an emphasis on these aspects. Although the management method used mobile phone lines, there were no problems with reliability or operability, and it was adopted because the introduction cost was the lowest.

Tottori Prefecture, Yazu Town

Product adoption for new construction and renewal. Contributing to leak detection and cost reduction.

1. When introducing the system in areas without a central monitoring device, a proposal method was adopted, and the “Yakumo Suishin” monitoring system using the Internet, which does not require a server device, was adopted from the perspective of construction costs, maintenance costs, the advanced nature of the monitoring content, and stable daily supply.
2. “With a monitoring system that uses the Internet, the status of the facilities can be checked from the site or from home using a mobile phone or computer, which reduces the burden of maintenance work.

In particular, we expect that the ability to check the facility status from anywhere in Japan will make it easier to establish an initial response system and ensure a stable supply.
In addition, the cost of servers, etc. can be reduced, and communication costs have been reduced by approximately 60%.”

Tottori Prefecture, Chizu Town

Responding to lightning damage and aging

1. In 2006, there were a series of damages caused by lightning strikes to the control units and notification devices of manhole pumps.
2. “In 2008, similar lightning damage occurred, and due to a failure of the notification device due to aging, sewage overflowed up to the floor level of neighboring houses, and compensation for damages was paid.
3. In response to these incidents, we entered into a 10-year lease agreement for 57 manhole pumps in 3 agricultural community drainage facilities that had been aging.”
4. In addition, a high-performance lightning protection system was also adopted, achieving the first 5-year full warranty against lightning damage, including direct lightning strikes, in Japan.

“We have not suffered any lightning damage, it is resistant to disasters, and it is also useful for organizing documents.

We would like to introduce it to all manhole pumps in the future.”

Kagoshima Prefecture, Kirishima City

Simultaneously realized the monitoring of 120 facilities in the former 1 city and 6 towns

1. Kirishima City was born in November 2005 through the merger of 1 city and 6 towns: Kokubu City, Mizobe Town, Yokogawa Town, Makizono Town, Kirishima Town, Hayato Town, and Fukuyama Town.
2. The city area is almost the same size as the 23 wards of Tokyo, and the monitoring of 120 water facilities was carried out by the former cities and towns using various systems, but it was integrated into Yakumo Suishin in 390 days.
3. The communication costs for the telemetry of the conventional monitoring system were 11.6 million yen per year, but the introduction of Yakumo Suishin has cut communication costs by more than half.
4. In addition, it has played a major role in responding to natural disasters such as water pipe freezing and the Kumamoto earthquake.

Tokyo, Musashino City

Yakumo Suishin for rain countermeasures. Protecting lives through “visualization” to realize self-help and mutual assistance.

1. In addition to installing rainwater storage and infiltration facilities on the grounds of all elementary and junior high schools in the city, and developing rainwater discharge trunk lines, a rainwater storage facility with a capacity of 4,500 cubic meters was developed in the Kichijoji Kitamachi district, which had suffered significant damage in the past.
2. Yakumo Suishin was introduced to efficiently coordinate and manage the rainwater storage facilities at 5 locations, including the 4 combined improvement storage facilities in the city for the purpose of improving the combined sewage system.
3. By linking the water level in the storage tank with the trunk line water level and automatically adjusting pump operation, the optimization of the water supply volume is realized.
4. The water level in the facility is monitored in real time and provided to citizens as a public website.
