Kubota's Vision for
Smart Water Solutions

IoT-Based Solutions for Water Environments that Realize Sustainable Infrastructure
to Withstand Population Decline and Natural Disasters

Water infrastructure is indispensable for people's lives, but today it faces a number of challenges, including declining populations, threats of natural disasters, and aging water facilities. Kubota's Smart Water Solutions will be the way we strive to address these issues using IoT.

For more than 130 years, Kubota has been involved in the development of a wide range of product development as well as facilities design, construction, and operation for the entire water cycle, from upstream to reuse to downstream. Because we have constantly been considering ways to provide new value, we will take on new challenges in solving water infrastructure issues in Japan and worldwide using the IoT solutions that only Kubota can offer.

Our Challenge

Issues Facing Water Infrastructure

Japan's water infrastructure is facing challenges that stem from three main causes: population decline, climate change, and an increase in natural disasters. Maintenance of this infrastructure was traditionally dependent on economic growth, but that has become a challenge, and methods will need to be revised under new social structures.

Dealing with Population Decline

Japan is facing a rapidly aging population and declining birthrate, and further population decline is forecast for the future. A smaller population means fewer people using water services, and this will directly result in decreased revenues for the municipalities that manage water systems. There are concerns about this leading to insufficient budgets for maintaining a reliable water infrastructure, including maintenance of pipelines and facilities.

There are also concerns about a decrease in the number of engineers and the aging of personnel as the population declines, so it will be necessary to reduce the amount of workforce and labor required to operate and manage water infrastructure, and to hand down technical skills to future generations.

Handling the Aging of Facilities and Pipelines

Japan's water infrastructure, with its world-leading quality, was mostly developed during the country's postwar economic boom. Now, more than half a century later, the time has come for upgrades to the system's facilities and pipelines. Efficient and steady upgrades will be an unavoidable challenge for maintaining a reliable water infrastructure for the coming years.

Resilience to Natural Disasters

Today, the risk of disasters throughout the world is heightened by global warming and climate change. In Japan, flooding caused by typhoons and torrential rains has been occurring more frequently, and communities and infrastructure need to be resilient against these disasters.

Our Approach

Problem-Solving Approach

Today, there are calls for the construction and operation of more sustainable water infrastructure, including management improvements in local governments, while confronting the challenges at hand. For this to happen, IoT will be indispensable for utilizing the information from the real world in digital form and achieving efficiency and labor-saving in various aspects. Kubota aims to realize value in five areas through solutions utilizing IoT.

  1. Accurate Monitoring and Lifespan Prediction for Facilities and Pipelines It will become possible to detect signs of abnormalities in facilities and pipelines and predict their service life.
  2. Cost Management Facilities revenues will be managed effectively and efficiently in view of declining populations, and suitable plans for replacing facilities will be formulated.
  3. More Efficient Operational Systems and Methods Workforce optimization and labor saving for operations and management will be achieved through relevant operational controls and other means.
  4. Risk Management Risk tolerance will be enhanced by enabling forecasting of disaster risks and remote monitoring of operations and services when disasters occur.
  5. Transfer of Operational Knowledge Utilizing IoT, knowledge related to facilities, product management and cost management gained through experience in operations and services will be transferred without human intervention, and support will be provided to inexperienced engineers.

Our Strength

Advantages Kubota Can Bring to Water Infrastructure Utilizing IoT

Service and Maintenance Made Possible by Involvement in Products

In addition to supplying products, Kubota handles the engineering design, procurement, construction, and maintenance of facilities and equipment for water infrastructure. What products are needed for these facilities? And what features do our products offer once they are delivered? Because we are involved in the hardware or physical aspects of products, we can provide optimized operations and maintenance for facilities and equipment.

And because Kubota offers a wide range of water infrastructure related products and services, we can provide products, service, and maintenance in a variety of formats, including stand-alone products, PFI/PPP*1, and EPC*2, to meet the diverse needs of local governments.

  1. *1.PPP (Public and Private Partnership) refers to a scheme in which the public and private sectors cooperate to provide public services. PFI (Private Finance Initiative) refers to a PPP method in which the construction, maintenance, management, and operation of public facilities and other aspects are carried out using private-sector funds, management capabilities, and technical expertise.
  2. *2.EPC (Engineering, Procurement, and Construction) refers to a full series of processes that includes engineering design, procurement of materials and equipment, fabrication, and construction work.

Utilizing IoT in Coordination with Products

As population declines pick up speed, labor-saving and efficiency in management and operation of water infrastructure will be more important than ever. The key to achieving these goals is the utilization of IoT. Kubota provides KSIS (KUBOTA Smart Infrastructure System), which enables remote management of water infrastructure facilities and equipment and visualization of their operating status, as well as prediction of irregularities in advance using analysis of monitoring data. Kubota also provides software such as WATERS-Cloud, a digitalized pipeline map that can also support water and sewage systems in which other manufacturers' products are used.

In addition to monitoring, diagnosis, forecasting, and control of pipes and facilities in waterworks, sewage, industrial waste water, agricultural water, and river water, KSIS also provides IoT-based solutions for waterworks repair sites. Hachinohe City in Aomori Prefecture, Japan has introduced one such construction information system, and it is contributing to solving the issues faced by the local government, such as improvements in accuracy of construction management and labor-saving.
