There are two key datasets that provide information on Water Company sewage releases.
Event Duration Monitoring (EDM) provides information on when and for how long sewage discharges have occurred. All EDM data is published online annually since 2020
Operator Self-Monitoring (OSM) compliance sample data is self-reported by the water companies and provides information on the quality of the final effluent which is discharged from sewage treatment works with numeric limits in their permits. This data is available for the Foss and Ouse and their tributaries for each of the last 5 years via: Open WIMS data.
