Southern Water has been fined more than £7.1 million after a series of illegal sewage discharges polluted the Kent coastline, forced the closure of popular beaches and exposed what a
judge described as serious failures in the company's wastewater management.
The sentence was handed down at Canterbury Crown Court on Friday following a prosecution by the Environment Agency over five major pollution incidents between 2019 and 2021. The court heard that preventable equipment failures, poor maintenance and inadequate operational oversight repeatedly allowed untreated sewage to enter coastal waters.
The case comes almost exactly five years after Southern Water received a record £90 million fine over nearly 7,000 illegal sewage discharges.
Investigators found that many of the incidents could have been avoided if critical pumping equipment had been properly maintained and faults identified sooner. The company also repeatedly failed to notify the Environment Agency promptly, delaying warnings to local authorities and the public.
One of the earliest incidents occurred in July 2019, when around 10 million litres of untreated sewage flowed into the sea over nearly 24 hours after staff failed to respond effectively to equipment problems. Southern Water did not report the spill until the following day, preventing Thanet District Council from issuing timely advice to swimmers.
More than a year later, during the August bank holiday in 2020, two pump failures at Margate led to another major release, with an estimated 16 million litres of sewage entering the sea over two days. On the same day, another pumping station at Broadstairs discharged between 1.6 million and 3.2 million litres of untreated wastewater into coastal waters.
The Broadstairs incident was not reported to the Environment Agency until weeks later, again leaving local authorities unable to warn beach users about potential health risks.
Further pollution incidents followed in 2021 after failures at pumping stations in Broadstairs and Margate. In February, equipment breakdowns prompted warnings for swimmers to stay out of the sea along a five-kilometre stretch of coastline for 24 hours.
The most disruptive incident came in June 2021, when simultaneous failures at both pumping stations sent sewage and debris into the sea just as beaches filled following the easing of coronavirus restrictions. Thanet District Council closed 11 beaches, while public advice urged people to avoid entering the water for a week during the height of the summer season.
Another equipment failure in October 2021 resulted in untreated sewage and sanitary waste being discharged into the sea, forcing the closure of 10 beaches.
In addition to the five principal cases, Southern Water admitted responsibility for 35 further illegal sewage discharges between 2019 and 2021. The company also acknowledged that a key sewage pump had remained out of service for more than a year.
Environment Agency manager Lindsay Faulkner said the repeated pollution incidents had caused avoidable harm to both the environment and coastal communities.
She said stronger oversight by Southern Water was essential, adding that the regulator would continue inspecting wastewater treatment facilities and holding the company accountable.
