Southern Water has been fined more than £7 million at Canterbury Crown Court after admitting to illegally pumping sewage into coastal waters off the Kent coast between 2019 and 2021. The penalty was handed down following an investigation by the Environment Agency, which uncovered repeated breaches of environmental regulations.
Details of the Offences
The court heard that Southern Water discharged untreated sewage on multiple occasions from storm overflows and treatment works, contaminating beaches and marine habitats. The illegal discharges occurred at several locations along the Kent coastline, affecting popular bathing waters and protected areas.
Environment Agency officers presented evidence showing that the company failed to properly operate and maintain its sewage treatment infrastructure, leading to unauthorised releases. Between 2019 and 2021, Southern Water recorded at least 30 separate incidents of illegal dumping, some lasting for hours.
Impact and Response
The fine, one of the largest ever imposed on a water company in the UK, reflects the severity of the pollution. The Environment Agency stated that the discharges posed a risk to public health and damaged local ecosystems, including shellfish waters and bird habitats.
In a statement, an Environment Agency spokesperson said: "This fine sends a clear message that we will not tolerate illegal sewage dumping. Southern Water's actions were a serious breach of trust and environmental law."
Southern Water apologised for the offences and said it has since invested in upgrading its treatment plants and monitoring systems to prevent a recurrence. The company also agreed to pay costs of £150,000.
Broader Context
The case is part of a wider crackdown by regulators on water companies polluting England's rivers and coasts. Southern Water has faced previous penalties, including a £90 million fine in 2021 for similar offences, and is under investigation for other alleged breaches.
