Given the current state of risk for infrastructure, municipalities face challenging decisions to plan the integrated repair/renewal of road, water, and sewer (RWS) networks. The research presented in this article identifies a methodology and framework that facilitates decision-making processes used during corridor rehabilitation project planning. A risk-based decision-making approach is developed to aid integrating repair/renewal of RWS assets. The risk model was developed using a mixed Delphi-Analytical Hierarchy Process approach. The impacts of four main consequences of failure with eighteen subfactors were considered. The RWS networks indices were amalgamated and grouped into an overall integrated risk index using K-means Clustering technique. Data provided by the City of Guelph was used in a case study in order to demonstrate the model features. Results show that pipe/road size and accessibility factors had the highest impact on the integrated risk index. The developed models can be used by researchers and practitioners (municipal engineers and consultants) to prioritize corridor rehabilitation projects thereby easing the challenge faced by stakeholders regarding the future of municipal infrastructure.

In Canada, the replacement/rehabilitation cost of water mains is estimated to be $28 billion (1997–2012). Therefore, selecting cost-effective repair and/or rehabilitation scenario(s) is essential to optimise the quality of existing water mains and minimise unnecessary rehabilitation costs.

Monte Carlo simulation approach is used to develop a stochastic life cycle cost (SLCC) model and methodology in order to compare different rehabilitation scenarios/alternatives for infrastructures, such as water mains. The presented research in this paper identifies several rehabilitation methods for water mains, which are classified into three main categories: repair, renovation, and replacement. The developed model helps academics and practitioners (e.g. municipal engineers) to predict the suitable new installation and/or rehabilitation programs as well as their corresponding costs, thereby, to avoid any unpleasant surprises.

This infrastructure enables the City to deliver services to London residents. The areas covered in this report include Water, Land. This report reviews our assets and forms a picture of our asset base as a snapshot in time at the end of 2012 which can be used to inform and guide decision-makers.
