Public Service Electric and Gas Co. (PSE and G), with more cast iron than any other utility in the US, has developed cast-iron main break predictive models encompassing effects of weather, soils, corrosivity, installation vintage and annual replacement footage. While these models will not produce a segment-by-segment replacement priority listing, they will highlight geographic areas of cast iron vintages that are more at risk than others. The models are comprised primarily of information readily accessible to most gas utilities. PSE and G's distribution network consists of more than 15,000 mi of main of which 5,100 mi, or 34%, is cast iron. Developing informational tools about cast-iron main reliability has been pursued by the company in various studies, and some of the results have been incorporated into the system management philosophy.
