Abstract

Traditionally, municipalities have constantly been a “step behind” in managing the municipal, and this is especially true of sewer systems. Municipalities have addressed the design, construction, maintenance, and rehabilitation of sewer systems by a “crisis-based” approach. Sewers are not built and/or rehabilitated until a major failure (i.e., overflow, collapse) occurs. This reactive management practice has led to inefficient use of funds and causes more frequent sewer failures, which end in difficult and costly repairs. For municipalities to be a “step ahead” in managing sewer systems, they need to have a better understanding of the existing condition of the network, which in turn will help them plan and manage maintenance to prevent major failures.
