Using a digital twin to achieve net zero in wastewater treatment

This panel discussion explores how digital twins are being applied in wastewater treatment to optimise operations, reduce energy consumption, and support the transition to net zero. 

Designed for monitoring professionals, utility engineers, plant operators, and sustainability managers, the presentation offers both conceptual foundations and implementation insights. Topics covered include:

• What is a Digital Twin?
  An introduction to digital twin architecture in the context of water treatment, including model-based simulation, real-time data integration, and bidirectional feedback loops. The speaker outlines how digital twins differ from traditional modelling and SCADA systems.

• Instrumentation and data infrastructure
  A walkthrough of the sensor networks and telemetry systems required to power a digital twin—covering flow meters, pressure sensors, energy monitors, and process instrumentation. The talk also addresses integration with existing control systems and data platforms.

• Energy and emissions optimisation
  Practical examples of how digital twins help identify inefficiencies in aeration systems, pump operation, and chemical dosing. The speaker explains how scenario modelling is used to reduce energy usage and quantify emissions savings in line with net-zero goals.

• Predictive capabilities and ‘what if’ simulations
  How digital twins enable forward planning through scenario testing—e.g., how changes in influent quality, weather, or equipment performance could impact operational outcomes. The system’s ability to recommend optimised control strategies is also explored.

• Operational benefits and ROI
  Discussion of key benefits, including reduced operational costs, improved environmental compliance, and strengthened resilience to changing conditions. The speaker shares real-world metrics from early adopters, illustrating strong return on investment and measurable carbon reductions.

• Challenges and lessons learned
  Insights into the practical challenges of implementation—data quality, calibration, stakeholder engagement, and skills development. The presentation also includes advice on phasing deployments and maintaining digital twin accuracy over time.

• Future directions
  A look ahead to the next phase of digital twin applications in water utilities: full automation, AI integration, lifecycle carbon modelling, and system-wide optimisation across catchments and energy grids.

This session is essential viewing for professionals seeking to modernise wastewater operations with cutting-edge digital tools, while delivering on net-zero commitments through intelligent monitoring and control.
