Received an order from Kyushu Regional Agricultural Administration Office for fabrication
and installation of pump equipment for the No. 2 and No. 3 drainage pumping stations of
the Kunisaki Western Coastal Conservation Project [Orders Received in March 2024]

These drainage pumping stations will be constructed on both banks of the Akasaka River, which flows through Bungotakada City, on the west side of the Kunisaki Peninsula in Oita Prefecture. The Akasaka River flows into the Suonada Sea, the shallow waters of which have long been considered suitable for reclamation, with new rice paddies being developed there since the mid-Edo period. The cultivation of white onions has flourished on this reclaimed land, making it the largest producer in western Japan.

Levees and other coastal protection facilities were constructed as part of the national West Kunisaki Land Reclamation Project implemented more than 50 years ago, but they have since deteriorated. In addition, the combination of increasingly heavy rains and reduced capacity of the existing drainage pumping station has resulted in frequent flooding of crops and other damage, causing anxiety for the local residents. In response, it was decided to construct new drainage pumping stations No. 2 and No. 3 adjacent to the existing drainage pumping station.

The bidding for this construction project was based on the general evaluation method, and the task of the technical proposal was to “devise ways to facilitate the operation and management of pump facilities.” Torishima submitted a proposal that met both explicit and implicit
needs, and received the highest score among the seven participating firms, leading to the award of the contract.

Once the new drainage pumping stations are completed, the drainage capacity will be restored, farmland will be protected, and local farmers will be able to farm in peace. Design and fabrication is underway, with completion scheduled for March 2026.
