Business content/features/appeal points
Business content and features
 We do general waterways business, including the Aquapig construction method, and maintenance of waterworks facilities, which are the most important of the essential services. Waterways mean the paths that water passes through, and our waterways business has a business model that focuses on the integrated maintenance of the paths that tap water passes through, from upstream to downstream.
[Our appealing points]
Our company has built a business structure that performs maintenance for everything from the highest point upstream to the lowest point downstream, including (1) state-of-the-art robots that can survey and clean the water in the water reservoir upstream, (2) the Aquapig construction method that cleans the inside of the water pipes midstream, (3) cleaning of the water supply pipes using ozone downstream. We not only clean water pipes, but we also clean the pipelines inside large factories run by private companies.
 [Aquapig construction method]
 The Aquapig construction method is used to survey and diagnose pipelines that are of concern. This is a surveying and cleaning method that is suitable for periods of maintenance and crisis management, involving order-made design and construction according to the site conditions to resolve such issues.
