Scottish Water Overflow Event Reports to SEPA, 2021-2025

Five years (2021-2025) of reported overflow event data from Scottish Water to the Scottish Environment Protection Agency (SEPA). The data includes discrete overflow events lasting more than 15 minutes 30 seconds, with start/stop times, durations, volumes, and asset information. It is published by Scottish Water under the OGL-UK-3.0 license and includes a version history for tracking changes.

Use Cases

• Analyzing overflow frequency and duration trends based on the reported annual event data.
• Modeling discharge volumes and environmental impact based on reported volume (m3) per event.
• Mapping overflow locations and their receiving waters based on provided coordinates and discharge points.
• Tracking regulatory compliance and permit reporting requirements over the five-year period.

Strengths

• Covers a five-year time range (2021-2025) for longitudinal analysis.
• Includes detailed event-level data such as start/stop timestamps, duration, and volume (m3).
• Contains a version history tab for tracking changes to the dataset.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
