An expert system for assessing the technical and economic risk of pipe rehabilitation options

作者:

Highlights:

• Investment in ageing infrastructure is a significant societal challenge.

• Cast iron pipes still constitute a significant portion of many water networks and various technologies are available to rehabilitate them.

• Under certain circumstances, trenchless renovation can be considered a prudent option, as can the use of trenchless replacement.

• Diffusion of such innovations in the USA is lagging in comparison to other countries.

• An expert system has thus been developed to facilitate asset managers to make risk appropriate selection of rehabilitation technologies.
