Building a Defensible Framework for Prioritizing Water Main Rehabilitation and Replacement

Customers, regulators, politicians and other stakeholders are forcing utilities to justify their capital decisions in the public forum using defensible, objective processes. Using case studies from several large and mid-sized utilities, this presentation will describe how a combination of analytical techniques such as statistical failure forecasting and correlation analysis, pipe service life modeling, and risk-based decision making tools (leveraging GIS, hydraulic modeling, customers service and CMMS [computerized maintenance management systems] data) can be used to lay the foundation for justifying capital projects. It is the combination of the technical approaches and the right messaging that gives utility managers the ammunition that they need to defend worthy capital projects.

James Carolan - CDM

Mr. Carolan develops, implements, and manages data conversion/ development methodologies for a broad range of geographic information system (GIS) projects. He uses GIS technology to create complex data development and quality control procedures for use in building large-scale, municipal information systems. Mr. Carolan is currently coordinating the design and development of state of the art, long term capital planning studies at CDM Smith. These leverage data and spatial analysis to better identify risk and consequence in ranking water system assets. Mr. Carolan has experience implementing and integrating GIS data and software with a wide range of other software packages, including work order management systems, capital planning software and databases such as Microsoft Access, SQL Server, Oracle and SAP.
