Concrete is the most commonly used material in sewers which can be attributed to its strength, durability and relatively low maintenance costs. However, due to the nature of concrete and the unique sewer atmosphere, corrosion of concrete pipes and associated infrastructure has been widely recognised as a significant challenge for the utility industry.
Corrosion can have significant economic, structural and performance impacts on critical infrastructure across numerous sectors. Understanding its impact and knowing how to prevent it is an essential part of an organisation’s asset management strategy. A panel discussion at the recent Asset Management for Critical Infrastructure 2018 conference in Sydney, looked at the importance of design criteria and material selection in preventing corrosion.
