This study aims at Tainan City sewage systemas a case stusy for the analysis of early warning and maintenance on mixture of rainwater and sewer by geographic information system (GIS). Results show GIS can calculate and display the alerts and pre- view how disasters made. Furthermore, the operation of connecting pipes associated with sewage intersection stations and pumping stations can rapidly flow out the sewer and stormwater before flooding happens. In addition, emergent pumping of flow by various stages in water treatment plants can show the effective response for avoiding the disaster of flooding. Finally, according to priority analysis, checking the maintenance area can reduce financial expenditure as less as possible.
