This report includes a rational and practical set of inspection guidelines, i.e., best management practices, for ferrous force mains which can be implemented by wastewater utilities in their condition assessment programs. The report includes: 1) A compilation of identified needs in terms of ferrous pipeline investigation from a national survey of wastewater utilities, 2) a review on ferrous pipelines of the modes of failure and the reasons, with related cost information, 3) a review of ferrous pressure pipe investigation technologies, and 4) a provisional set of guidelines for investigating ferrous force mains to be implemented during forthcoming fields trials.
