01 / THE CHALLENGEWhat needed to change
Wastewater operations generate large volumes of telemetry and alarms. Without a consistent pipeline, it is harder to interpret sensor history, spot unusual patterns and give operational teams a reliable view of changing conditions.
02 / THE APPROACHHow the solution was shaped
The documented design used Azure and Databricks pipelines with PySpark to process telemetry and historical event data. Delta and Parquet storage supported the data flow, while anomaly and flatline detection, maintenance flags and summary tables made signals available for Power BI views and alerting.
03 / PRACTICAL VALUEWhat this makes possible
The case shows how data engineering can connect raw equipment signals to operational questions: where attention may be needed, what has changed over time and which patterns deserve investigation.
