Yorkshire Water cites prolonged rainfall for system pressure issues.
Environment Agency is investigating the ongoing discharge incident.

An investigation has been launched into a water treatment works in Atwick, East Yorkshire, following reports of untreated water being discharged into a nearby stream. Data indicates this discharge began on January 6th and has continued for nearly three weeks, accumulating to approximately 500 hours. Yorkshire Water stated that prolonged and heavy rainfall caused system pressure, leading to the discharges to protect nearby properties. The Environment Agency confirmed its investigation and has instructed Yorkshire Water to provide crucial information for permit compliance assessment. Environmental campaigners have voiced serious concerns about potential pollution in the area, with one noting the potential for widespread contamination. Combined sewer overflows (CSOs) are designed as safety measures during heavy rain to prevent water backup into homes, but their impact on water quality remains a significant concern nationally. In 2024, England and Wales recorded over 563,000 CSO spills. Yorkshire Water has outlined plans for future investment in Atwick to upgrade the sewer system, separating surface water from wastewater to reduce such occurrences.
