16 Sewernet – SPS Future Control and Benefits Target Objectives ‘Critical plant’ tests Predicted Rainfall (ERA) Currently Available data Remote operation of pumps Continuous alarm prioritisation Rate of change Starts & stops Idle time Alarm Volume reduction Analysis & control (exploiting Fuzzy logic and ANN techniques) Future data Liquid Level High Level float Back up float Overflow Wet OR Dry SPEOR Energy tariff LOS Improve pump performance Alarm management

17 Sewernet Process Values Data Quality Monitor Multivariate Process Monitor Converts process data into meaningful, trustworthy information Identifies events that are out of the ordinary Analyses and forecasts operational behaviour Increases uptime Handle noisy data Re-construct bad / missing data Confidence Metrics Predictive Diagnostics Process KPIs Operator Advisor / Closed Loop Reduces process variability Defines optimal operational setpoints Provides Soft Sensors Business KPIs Intelligent analysis of data

18 Sewernet Weather Radar data exploitation OMC and Operations monitoring & Planning tool Flood Mapping – Predictive management/ Real-time benefits Asset Planning information

19 Sewernet Visualisation – OMC Dashboard

20 Sewernet – Alien Technologies? Telemetry exploitation Previous endeavours New technologies Linguistic variables! Artificial intelligence

21 Sewernet Overall Benefits Possible Event Management (Pollution reduction, Environmental protection, Improved levels of service) Reduced operational costs (Maintenance reduced, better planning possible) System optimisation (Rainfall runoff management, DWF Load and flow management, Storm Flow management, Flow smoothing to STW) Energy Cost Savings (Optimised pumping, tariff management)

22 Sewernet Further Opportunities Inflow and infiltration assessment FOG and Sediment control, blockage management Rapid location of blockages Optimal Maintenance regimes (- Asset Trigger Monitoring) Telemetry System optimisation Data management and visualisation Intelligent analysis of data Real time monitoring and control of sewer systems
