Sewerage has been developed with the major objectives of "inundation control," "improvement of public health", and "conservation of water quality in public water areas". In recent years, in addition to these purposes, the practical application of the recovery of resources and energy of sewage such as phosphorus recovery and methane fermentation has been attempted. On the other hand, although the facilities are becoming obsolete, it is difficult to renew the facilities due to the financial situation and the declining state of the population. Therefore, it is required to appropriately manage the existing facilities. In order to achieve these objectives and perform more appropriate value-added operation management, it is necessary to collect the necessary and sufficient information and utilize it. In this study, the possibility of various information that sewerage has is considered. The water quality of effuluent from a wastewater treatment plant is predicted by machine learning using the operation & management data acquired every day as an example of information utilization. The ideal ways of sewerage as an information base in the catchment area are considered and discussed as well.
