– a one-off event to highlight the sewage pollution of the River Derwent SSSI in Malton and Norton, by Yorkshire Water, North Yorkshire Council and the Environment Agency.

Yorkshire Water sewage spill data for Malton, Norton and Old Malton 2019, 2020, 2021, 2022, 2023 and 2024 (latest data published on 27 March 2025). The figures are taken from the Environment Agency EDM (Event Duration Monitoring) records and The Rivers Trust Sewage Map. Spill data submitted by Yorkshire Water confirms that the Yorkshire Water sewerage system for Malton and Norton is not fit for purpose.

The EA and Rivers Trust data for Yorkshire is complemented by the Yorkshire Water Live Storm Overflow Map. More about the map here.

The EDM records show the number and duration of sewage spills into the river Derwent SSSI which amounts to thousands of hours each year due to the lack of capacity in the sewerage system to accomodate the volume of sewage produced by the towns.

Yorkshire Water sewage ‘spill’ data for 2019, 2020, 2021, 2022, 2023, 2024.
