Concrete Sewer Systems and Wastewater Processes Related to Concrete Corrosion

Sewer systems is the cornerstone of modern urbanisation by providing wastewater collection and transport, which enables not only the recovery of water and resources but also the control of odour and harmful pathogens. Sewer systems are primarily composed of rising main pipes, gravity flow pipes, pumping stations and other associated facilities. Complicated physical, chemical, and biological processes are occurring in the phases of water, air and concrete, and their interfaces. These processes significantly affect the concrete durability due to microbiologically influenced corrosion.
