We develop and offer environmental equipment for improving sewage systems, septic tanks, gray water treatment plants, pollution treatment systems and other water treatment plants. In response to diverse needs, including those for improved treated water quality, lower running costs and easier maintenance and management work, we identify and propose the environmental equipment that functions most effectively throughout the whole system, calling on the extensive experience and track record in the construction, maintenance and management of water treatment plants we have accumulated as a general consultant on water.
