Water and Industrial Water Treatment System

Although the spread of tap water supply in Japan has progressed, the country needs to improve the stability of the supply system against droughts and disasters.
In response to stricter tap water quality standards and the demand for high-quality drinking water, Kanadevia is conducting surveys, design, and construction for an integrated system spanning from water intake to water purification.
Moreover, in anticipation of future population decline, we also propose an individually distributed water purification system that is resistant to consolidation/reconstruction of facilities and disasters.

Sewage Treatment System

Based on many years of experience and achievements, Kanadevia is using our advanced technology to protect the beautiful and irreplaceable aquatic environment. Furthermore, by developing and providing energy-saving and resource-recovering technology, we are working to reduce the environmental load of sewerage and build a recycling-oriented society.
From large-scale to small/medium-sized sewage treatment facilities and wastewater treatment facilities for farming/fishing villages, we propose the optimal plan according to the treatment scale, future plan, and regional characteristics.
