STATISTICAL COMPARISON OF TREATMENT PLANTS ALONG THE RHINE AND DANUBE

Abstract

The collection ofthe municipal sewage treatment plants' data of the Rhine and the Danube basins, initiated by the RBA-Centre, Delft University of Technology, was continued with the development of a database manager. The name of the program is 'Information on Municipal Sewage Treatment Plants', IMST. The main goal of the IMST was to make the continuation of the collection of waste water treatment plants possible without significant knowledge of informatics and to provide a tool to compare the municipal sewage treatment plants from the Rhine and the Danube basins. The IMST is a user friendly, menu driven system with easily accessible modular system. Besides the data entry, list and simple, statistical and integrated query of the treatment plant data a map system is included to demonstrate the geographic location of the plants and to give a visualisation possibility of the main characteristics (country borders, watersheds, main rivers and their tributaries, etc.) of the two river basins. The system is opened and can be extended. Please bear in mind that IMST has been developed and is being maintained as a non-profit project form and educational and research institution. We are always pleased to hear feedback concerning your use of the system and any suggestions for improvement, additions and the like. Much of the nature of the system has to be derived from user suggestions. Please keep in touch!
