The Water Research Foundation (WRF) and the CSIRO National Flagship - Water for a Healthy Country are currently undertaking a research project with the aim of developing a decision support tool for small diameter cast iron pipes.

The purpose of this research is to develop a simple and practical tool in the form of guidelines and associated software that will facilitate asset managers to determine which cast iron distribution mains warrant renovation and which warrant replacement. The tool will focus on relatively small diameter (4 to 8 inch; 100 to 200 mm) cast iron water mains that are managed under a ‘run-to-fail’ strategy.
