Webinar: ARC Linkage Project: Sewer corrosion reduction through model-supported ventilation control

Professor Zhiguo Yuan AM will give a presentation outlining AWMC's newest ARC Linkage Project: Sewer corrosion reduction through model-supported ventilation control.

Sewer networks are a critical part of our urban infrastructure. Australia has over 110,000 km sewer pipes with a total asset value of $35 billion. Concrete is the most commonly used material for large sewers due to its strength and durability. However, concrete sewers are prone to sulfide-induced corrosion, costing Australian water utilities hundreds of millions of dollars each year for repair and maintenance.

Ventilation is one of the key technologies for sewer corrosion control. However, its design and operation are currently based on experience and empirical equations, often leading to unsatisfactory results.

This project aims to generate critical knowledge and predictive models for optimal design and operation of sewer ventilation systems, and to develop and demonstrate novel dynamic ventilation strategies to reduce sewer corrosion.

By extending service life of our sewer networks, this project will deliver large economic benefits to Australia. Well-operated ventilation will also reduce odour emissions from sewers, thus delivering social and environmental benefits as well.
