Company information
Dōei Kōgyō was established in 1970 as a cleaning contractor for sewer facilities. Since then, we have established a system that can respond to all needs in a one-stop manner, from sewer pipe inspections to rehabilitation work for repairing sewer pipes, and renewal work for replacing sewer pipes. Furthermore, leveraging that know-how, we are also expanding our business areas to include waterworks, general civil engineering, and building maintenance. As various infrastructures support people's lives, the requests we receive, primarily focused on maintenance and management, are all of high urgency. However, since we are entrusted with public infrastructure, we must protect people's comfortable living environments under any circumstances. The sense of mission that "if I don't do it, who will?" supports us. Moving forward, we aim for further evolution centered around the sewerage field. "Protecting the ordinary daily life." With that mission in our hearts.
