Water treatment

Water treatment

We are engaged in the construction, operation and maintenance of water treatment facilities in a wide range of fields from water supply and sewerage to industrial use. We support social infrastructure as an unsung force through our water-related engineering.
We continue to explore technologies to realize a carbon-neutral society, such as the effective use of sewage sludge and other biomass as gasification and fuel.

Appealing Points

No. 1 share in Japan

Steel plate digestion tank

The steel plate digester is a core technology for converting sewage sludge into energy, which is gaining attention from the viewpoint of carbon neutrality. The use of steel plates for the digester reduces construction costs and shortens the construction period, while sensors are installed to visualize the inside of the digester and ensure stable operation.
We currently have the largest share of steel plate digesters in Japan, and we are working to further promote the use of these digesters.
