Japanese Flood Prevention Facility
The planning and construction of drainage systems, equipped with deep underground conduits as primary reservoirs for storing run-off via inter-river linkage, are recently underway as a countermeasure against floods which threaten low and flat urban areas. The "Shutoken Gaikaku Housuiro" construction project features the building of Japan's largest-scale underground conduits. The main pumps used in the "Gaikaku Housuiro" drainage pump station are the largest such pumps in Japan as well. The following gives a general outline of this drainage pump station and introduces new technologies applied.
