SRV Bacteria Predictor

An ensemble model with a Gini Coefficient of 70+ was developed to identify service reservoir assets at risk of ecoli failures to direct manual investigations. Water quality samples are regularly taken from each of the 300+ service reservoirs located across Wales. These samples are analysed and the data uploaded to a centralised database. A legacy model was historically used to identify assets but stakeholders felt its performance had degraded to the point of no longer being fit for purpose. This model redevelopment project included:

• Extensive EDA.
• Data drift analysis.
• 10, 000: 1 class imbalance.
• Low capacity for on-site investigation required minimal false positives.
• Interactive Power-BI Dashboard.
