Wastewater network rehabilitation manager

This research group includes end-users that utilise powerful tools for network management. These tools are designed to identify failure patterns and cost-effective rehabilitation requirements for water distribution networks. They have developed separately and for different needs. It is clear that there is great potentialforharmonisation and optimisation of these tools, enabling a far more powerful and comprehensive approach to rehabilitation planning.

The starting point for this work package was to understand the differences and synergies between the tools. The nature and benefits of each will need to be fully understood in order to evolve a procedure for development and optimal, integrated application of the tools. Once the theoretical procedure for operation is specified, the task of integrating the software and modelling tools can begin. Data input, output, storage and handling were specified. A database was designed to handle the necessary data flows. It was be important to structure and configure this database so that it provides an effective conduit between corporate data systems and the CARE-S suite of tools. Finally, the prototype was delivered in a fully functional state of operation. The CARE-S database can be populated with typical network data; this will be flexible allowing manual or automatic data input from other corporate data systems. The prototype demonstrates efficient rehabilitation planning and it enables cost efficiencies and performance benefits to be quantified.

The final product of the CARE-S project is a prototype of the wastewater network rehabilitation manager, a suite of tools that include conclusive software and methods from WP 1-6. This manager will include all constraints and conditions that are relevant for decision on sewer and storm water system rehabilitation. The manager is presented by a joint GIS-based user interface.
