Factors influencing the structural deterioration and collapse of rigid sewer pipes

Abstract

This paper provides a review of the numerous factors that have been recognised as influencing the structural stability of rigid sewer pipes in the field. A description of the general process of rigid sewer pipe deterioration and failure is provided and the factors influencing this process considered in three main groups, namely, construction features, local external factors and other factors. Areas of contention and uncertainty are identified, as well as deficiencies in current understanding. General suggestions are made regarding possible directions for future research.
