This document discusses the development and benefits of a GIS-based application for optimizing sewer maintenance. It was created to increase sewer lifespan by calculating dynamic maintenance intervals using a damage forecast model. The application includes a digital work report, optimization tools based on work reports and various requirements. It provides benefits like tailored maintenance schedules and improved planning based on collected conduit data. The overall aim is to reduce pollution in rivers by optimizing sewer maintenance using MapWindow-based GIS tools.

6. WHY CHANGE THE FORMER PRACTICE?
• Objection: Increasing the sewers live span
• Method: Calculate dynamic maintenance intervals by a damage forecast model
• Material: Maintenance data are needed  a GIS based application is installed
