About
This environmental monitoring resource provides daily time series data detailing sewage overflow events managed by Thames Water, one of the UK's largest water providers. It integrates crucial operational metrics, such as the number and duration of spills, with corresponding precipitation measurements from across the catchment area. This combination allows for analysis of the relationship between rainfall conditions and wastewater infrastructure stress. The resource promotes transparency and supports efforts to address significant sewage pollution issues in South East England.

Distribution
The data is delivered as a daily aggregated version in CSV format, specifically the file
thames_water_aggregated_daily_sewage_spills.csv, with a file size of approximately 23.81 kB. It contains 14 columns and 366 records, where all records are valid. The dataset is expected to be updated quarterly.Usage
This resource is ideal for various analytical projects, including:
- Exploring temporal trends over time to identify how operational practices change.
- Developing regression models to predict future sewage overflow durations based on changing precipitation conditions.
- Conducting focused time series analysis related to environment and pollution.
- Creating visualisations that map environmental impact and water infrastructure stress.
Coverage
The dataset covers daily aggregated events reported by Thames Water, which provides services to over 15 million customers in South East England. The temporal scope includes records from April 2022 through to January 2024. Geographic coverage includes rainfall metrics collected from specific monitoring stations within the catchment area.
