Remote maintenance of water and sewage treatment plants and future maintenance

摘要

The environment of water and sewage treatment plants are faced with great changes such as measures to be taken against environmental problems, reduction in public construction expenses, and a wider district assigned to a plant. In addition, high-level maintenance as a life line is required. This paper describes the remote maintenance of complicated, sophisticated supervisory control systems and improvements in future maintenance work. In particular; maintenance on commission, various management services, and maintenance work support systems are proposed.
