Southern Water has been fined more than £7 million after dumping sewage illegally off the Kent coast between 2019 and 2021.
The company, said to have caused harm from “a pattern of repeated incidents over several years”, pleaded guilty to 13 offences at Medway Magistrates’ Court last April over sewage discharges at Margate and Broadstairs wastewater pumping stations between 2019 and 2021.
Nine counts related to the incidents of untreated sewage dumped off the Kent coast while three counts were over failure to notify authorities of the discharges as soon as practicable and within 24 hours of a warning which is a condition of its environmental permit.

The sentencing at Canterbury Crown Court took place across Thursday and Friday, with Mr Justice Johnson imposing a total fine of £7,127,083.
It comes after the company was fined £90 million for nearly 7,000 incidents across Hampshire, Kent and Sussex in a case brought by the Environment Agency in 2021.
On Friday, Mr Justice Johnson said there were “overall serious failures”, adding: “The defendant knew the importance of maintaining resilience systems and equipment at these sites.

“And it knew what the consequences would be if the system or equipment or individual components failed.
“It was well aware of the potential for equipment to fail and for the essential need for robust maintenance and testing procedures.
“That is because of the dozens of previous occasions on which that had happened.”
He told the court: “The harm was not confined to a single event, but arose from a pattern of repeated incidents over several years.

The judge said Southern Water is a “very large” organisation with annual revenue over the last three years between £800 million and £1 billion.
He said it has 174 previous convictions, convicted every year from 1999 to 2016, and convicted as recently as April of this year.
“The defendant’s record of convictions shows a protracted history of non-compliance with its legal obligations, and a repeated pattern of inadequate staff training, insufficient investment in the infrastructure and a failure properly to maintain equipment.
“It also shows a failure to respond to warnings from the courts, including the resident judge of this court and the Lord Chief Justice.
“This record of criminality, to the great detriment of the environment and the community in Kent, is an exceptionally serious aggravating factor,” he said.
On Thursday, the court heard details of the offences, including an intermittent flow of sewage on July 20 2019 at the Margate site that lasted from about 2am to just before midnight.
The Environment Agency was not notified until more than 32 hours after the first discharge.

It lasted for nearly five hours, and authorities were notified at the end of the discharge.
But prosecutor Andrew Marshall said the sewage that came out into the sea at a shorter distance from the shore was “unscreened” – which means solid waste remained in the sewage – and that there was a lot of sewage debris washed up on the coast.
Warnings were put in place on the beach between February 17 and 19 while company-contracted cleaners swept the beach for waste.
Pictures shown in court showed the pollution on the beach, and sanitary items in the sea.
The court also heard that sewage pollution discharges at Margate and Broadstairs stations between June 16 and 17 2021 led to 11 bathing waters being closed by Thanet council for a week in a “high profile pollution incident”.
Pictures shown to court showed waste in the water, closure notices and an empty beach with a red flag on display.

“These events took place more than five years ago – since then we’ve made significant changes.
“Under a new leadership team, backed by new shareholders, we’ve radically addressed our culture, governance and operations.”
The company said its responsibility now is to “continue delivering the improvements that will make a meaningful difference for our customers and the environment”.
