Drainage pump stations for flood prevention

A drainage pump releases as much as 50 tons of water per second and protects farmlands and residential areas from flood disasters

Where does the RAINWATER go after it rains? Some of the rainwater soaks into the ground, but the rest goes into gutters and drainage ditches and eventually flows into rivers. However, when a large typhoon hits, or when there is a heavy rainfall, water may overflow and may not flow naturally. This is where drainage pump stations play an important role. A drainage pump station is a facility that uses drainage pumps to pump rainwater and domestic drainage and forcibly drain it into rivers, preventing flood disasters. Recently, there have been reports from all over the world about rain-related extreme weather events, such as sudden heavy rain, torrential downpours, and record-breaking precipitation. As a result, the role of drainage pump stations will become increasingly important in the future.


EBARA has delivered pumps to more than 1,000 drainage pump stations in Japan and boasts an extensive delivery record, commanding top market share in Japan. We have been involved in one of the world’s largest drainage pump stations, with a drainage pump with a huge impeller of 3.8 m in diameter, with four pumps capable of draining approximately 50 tons of water in one second. With the world’s leading production technologies, we continue to protect people's lives from the risk of flood disasters.
