Water Quality Monitoring Technology and Information Collection System (WQMT-ICS)
On-line real time monitoring of wastewater quality has not previously been possible. Many "off-the-shelf" systems perform well in laboratory environments with clean water. However, wastewater quality is highly variable as well as physically and chemically problematic. These problems have contributed to the previous failure of other on-line monitoring systems.
The Urban Water Security Research Alliance developed a new event recording system which evaluates wastewater quality on-line, in real time. The event monitor was extended into a co-ordinated event detection system, to help identify excursions from normal wastewater quality caused by abnormal discharges to the wastewater network.
This project aimed to develop a fully functioning prototype event detection system for wastewater inflows to Advanced Water Treatment Plants. Such a system promised to be a powerful tool for source control, including the dumping of materials to the sewer system. It could also provide an early warning system for wastewater treatment plants, to safeguard operations and improve risk management in wastewater processes. The project was informed by the following research questions:
- How can electronics and control hardware be designed and fabricated to transform the current event recording system into a real-time event detection system?
- How can the mathematical model underpinning the system be further optimised?
- How will the mathematical model be “married” with new electronic control hardware?
- How with the event detection system be validated in a real-world situation?
- How can an event detection network be developed?
- How applicable is the developed system to other barriers in the South East Queensland (SEQ) water cycle and grid?
Key Publications and Outputs
The key output of this project comprises a number of on-line real time event detection systems deployed to monitor wastewater influent and effluent at a Wastewater Treatment Plant in SEQ. These systems conclusively demonstrated the proof of concept system, which could be commercialised in future.

The event detection system developed is viewed as an integral component of wastewater treatment management and protection of wastewater infrastructure and operation. This system is adaptable to other parts of the water treatment system and therefore is of high relevance to water service providers, as well as to those with responsibility for managing wider water quality in the SEQ Water Grid.
