UTILNETS-PROPAGATION OF SUPPORT SYSTEMS FOR WATER INDUSTRY BY GENERALISED INTERFACES

Objective

The project is based on the Decision Support System UtilNets for the rehabilitation management of water pipe networks. worldwide, a huge number of water pipes are reaching the end of their life expectancy. In the EU, maintenance costs of two billion ECUs annually have been reported. In England, Greece and Spain more than 25 % of water is lost due to leakage. Instead of prospective rehabilitations, too many expensive emergency repairs are performed. In this situation, information systems are needed to forecast the deterioration process and to focus rehabilitation budgets on the most important regions of each network.
In contrast to conventional systems, which are restricted to a statistical survey of the network, UtilNets takes into account all relevant environmental impacts over the whole life of individual pipes. The structural and hydraulic life expectancy of pipe segments is determined. The system optimises the individual rehabilitation policy and the ranking of rehabilitation within the whole network. It provides a profile of the network together with an assessment of rehabilitation expenditures.
UtilNets is based on much more input data than conventional programs. The collection of this data from pre-existing data sources will be automated by flexible import-export interfaces comprising : - data editor : User interface for storing new data not available from pre-existing sources. - rule editor : to specify knowledge in terms of users own expert language. - rule generator : several rules can be generated from the database. This procedure will be automated. - interface for utility-specific naming conventions (e.g. for pipe material types). - set definition for data acquisition : network elements with similar features are defined as sets. - interface for generalised definitions such as water types. - mass data : several options to transfer from existing databases will be explored.
In order to make the system applicable for other utilities, some parts of the modules must be made flexible. Therefore, a customiser will be developed. It will allow the user to change formulas by means of rules in terms of the expert language.
Nearly all utilities suffer from non-integrated water network information systems. An interface for risk analysis and economic results will improve the control of the relevant business processes and allow to adjust the standards towards best practice of integrated workflow.
