Our solutions/activities, initiatives, and deliverables

Our activities and initiatives in the market

The Infrastructure Company has installed pumps at more than 1,000 drainage pump stations nationwide. We provide sewerage and drainage treatment systems across Japan and have worked on one of Japan’s largest drainage pump stations, protecting people's lives from the risk of flood disasters. We also supply agricultural pumps to Japan and the rest of the world to ensure abundant food production. In addition, we provide ventilation fans for major tunnels in Japan, with ventilation control and smoke exhaust functions to realize safe and secure tunnels. We support people's daily lives by proposing optimal, customer-driven solutions in various fields such as water treatment, agriculture, and transportation.

Purification and discharge of sewage

Water used in homes and factories is transferred to sewage treatment plants through drainage pipes, where it is purified, and then discharged into rivers. Our pumps are used in sewers and sewage treatment plants across the country, providing a comfortable way of life.

Drainage pump stations for flood prevention

A drainage pump station uses forced drainage to prevent flooding during heavy rain. We have delivered pumps to more than 1,000 drainage pump stations across Japan and has an extensive delivery record, commanding top market share in Japan.

Water supply for agriculture

In today's world of population growth and climate change, agricultural pumps are of utmost imporatance. We deliver water to farmlands around the world to help solve food problems with our optimal pumping systems tailored to the terrain and climate.

Ventilation control in large tunnels

To ventilate tunnels and maintain clean air at all times, we supply ventilation fans to major tunnels throughout the country. Optimal ventilation control provides a safe driving environment.

Technology to support a safe and comfortable way of life

We have delivered pumps to a national project in China and drainage pump stations in Japan to eliminate water shortages, protect communities from flood risks, and support people's lives. We have also delivered ventilation systems to the Tokyo Bay Aqua-Line to provide a safe and comfortable driving environment. The Infrastructure Company has an extensive track record of delivering products in a wide range of fields, including the effective use of water resources, flood prevention measures, and infrastructure maintenance and management, contributing to the lives of people and further development of society around the world.

Lake Las Vegas water intake pump (USA)

In Las Vegas, a city in the desert, domestic water is supplied from the Hoover Dam, located 48 kilometers away. We have gained high acclaim for delivering special pumps that require advanced technology.

South-North Water Transfer Project (China)

The South-North Water Transfer Project is a grand plan to transport water from the south to eliminate water shortages in the North China region. We have supplied large tubular pumps, contributing to regional development.

Japan's largest drainage pump station (Japan)

Japan, a country with high precipitation and steep-banked rivers, has a high flood risk. Drainage pump stations are installed as a countermeasure against the flood disasters, and we have delivered many pumps in cooperation with the Ministry of Land, Infrastructure, Transport and Tourism and local governments.

Tokyo Bay Aqua-Line/Undersea tunnel ventilation system (Japan)

Our ventilation systems are actively used in the Tokyo Bay Aqua-Line, an undersea tunnel. The combination of natural and mechanical ventilation provides a low-cost and energy-saving environment for safe driving.

Actions for the future

We will combine all the strengths of the EBARA Group to generate synergy, use this group's collective strength to solve social issues, and aim for a prosperous and comfortable next 100 years.

Zero flooding

In recent years, severe flood disasters have occurred due to extreme weather, requiring countermeasures. By manufacturing pumps for domestic and overseas drainage pump stations, we aim for a future in which global flood damage is reduced to zero.

Water for desert regions

In order to create a future where everyone in the world has an access to water, we strive to contribute by eliminating the shortage of global water resources, leveraging on the technologies we have cultivated in the fields of water supply, sewage, and agricultural water fields in Japan.
