Abstract
Serious deteriorations on sewer pipe networks which is an essential lifeline supporting our life by an active consortium of bacteria are becoming a major social concern in many advanced countries in recently. Because the sewer pipe networks were generally arranged into the ground, it is expected to develop a rational method for preventive maintenance. This paper describes an integrated maintenance system for the sewer pipe networks combined with the latest information processing technologies and intelligent health monitoring techniques. It will be able to estimate the deteriorating conditions inside the pipe based on more accurate knowledge about the environmental conditions such as hydrogen sulfide gas density, temperature & humidity history inside the pipes, etc. from a monitoring system via information technology. This paper also describes a prototype maintenance system that was developed for a sewer pipe networks in Ube City area as a specific example.
