Based on QGIS and a database model for management of sewage system data, several tools are being developed for preparation and management of drainage system data and graphical presentation of the simulation results of urban drainage systems. Main focus lies on practical applicability by consultant engineers and the flexibility to connect to different simulation packages. By using one system for data preparation for different simulation packages, a higher efficiency leads to reduced time and costs. The data is stored in a database, either SpatiaLite or POSTGIS. The tools are developed using the database functions because of the high efficiency.
