The Vienna Sewerage Information System (KANIS)
The Vienna Waste Water Management (Wien Kanal) runs a digital Sewerage Information System (KANIS, short for Kanal-Informations-Systems) which not only facilitates management of the sewerage system, but also provides up-to-date service to third parties. Supplying extensive, continuously updated information, the integrated sewerage system data base supports efficient maintenance, cleaning and planning processes. The digitised data represent the sewerage system operation in great detail and are used for ongoing quality improvement measures. Third parties, such as construction engineers and builders, can easily find and retrieve the information they need online.
Sewerage system operators need extensive and accurate data as a basis for the daily operation and management of the system, as well as for planning future extensions and improvements. While these data may in principle be collected in conventional registers, development of a digitised information system is advisable for large sewerage systems. The KANIS sewerage information system is an important tool for current operations and proactive responses to future challenges, supporting efficiency, resource-effectiveness and speed of the sewerage management processes. Moreover, KANIS provides information for construction planners and property owners in easily accessible formats.
The KANIS data base contains extensive information about the Vienna sewerage system. In addition to mapping the location of the sewers, their dimensions and design, it also provides data on other important parameters, including structural quality, cleaning/maintenance, wastewater quality and odour, where relevant. All information is continuously updated, and the staff of Wien Kanal can retrieve data online, including graphic visualisations, from their office PCs. In generating KANIS, great attention has been given to easy communication and interchange with other data bases and mapping tools. A special feature of KANIS is that the system accurately describes curved sections of the sewers and allows processing of the relevant data for these segments.
With thorough data collection and continuous updating of the data base, KANIS supplies extensive real-time information to ensure efficient sewerage system operations and sustainable future planning of the system. The data base allows swift utilisation, evaluation and analysis of different combinations of data sets, facilitating decision-making processes for problem resolution and planning purposes.
For example, KANIS provides important basic data for hydrodynamic flow modelling and real-time sewerage system control. Evaluation of the sewerage system data enables Wien Kanal to prioritise maintenance and repair tasks and conduct them quickly and efficiently. If the pollution level of the sewage rises above the legal limits, KANIS protocol data are used to track the pollutants back to their source and identify the polluter.
Wien Kanal provides data and maps of the sewer system to outside customers, including construction engineers and builders, either in hard copy or as digital files. This service effectively helps speed up planning processes.
