BUBI: An Interactive Water Utility Benchmarking Website
A web-based benchmarking support system was developed to support management of water utilities. The tool helps experts to assess the performance of a utility and compare it with others. In addition the system is a tool for the utilities to publish their performance data. The web implementation allows co-operation and comparisons between utilities. A system of variables, comprising about 130 input variables and 120 output variables was developed and stored in the facilitator database. The facilitator hosts a website, which contains public, member only, and developers’ sections. The website includes interactive pages to access the facilitator database for for example benchmarking report generation, discussion, data input, and database development. The facilitator system was developed on a Linux-based GNU system and it utilises also several other freely available software packages, including a relational SQL database, web server, graphing programs and libraries, all of which are glued together with Perl programs. A general finding of the study has been that a website is a good candidate as a central element of an environmental information system especially when co-operation support is needed.
