Description
The School Water Consumption & Anomaly Detection service provides the Municipality of Athens with continuous monitoring of water consumption across instrumented schools, using occupancy-adjusted baselines to detect anomalous flows, background leaks, and wastage events during unoccupied periods. The service makes water losses visible as they develop, giving facility managers the information needed to act before waste becomes financially significant.
Core Capabilities
Monitoring & Anomaly Detection
Business Need
Water losses in school buildings — running cisterns, slow pipe leaks, irrigation systems left active outside school hours — frequently accumulate undetected for weeks or months before surfacing in utility bills. The service makes these invisible losses visible and measurable in real time, providing the Municipality with an automated monitoring capability that flags waste events with financial significance estimates, enabling targeted maintenance action before costs escalate.
Key Performance Indicators
Detection precision: proportion of alerts corresponding to confirmed waste events
Alert timeliness: time from waste event onset to first flag raised
Baseline accuracy (MAPE): deviation between projected and actual consumption during occupied periods
False positive rate: proportion of alerts attributed to legitimate consumption on investigation
Data Provided
Water meter readings at high temporal resolution from instrumented schools
Occupancy schedules from Greek school calendar and term dates
Estimated waste volume in litres and cost equivalent per detected event
Weekly portfolio summary ranked by anomaly status and cumulative estimated waste
Per-school consumption status with baseline deviation context
