Overview
- The company was sentenced at Canterbury Crown Court on Friday and ordered to pay a total fine of £7,127,083 after pleading guilty to 13 offences linked to Kent coastline discharges.
- The convictions cover nine counts of untreated sewage being dumped into coastal waters, three counts for failing to notify regulators within the timescales required by its environmental permit, and one count for not having a standby pump at Margate between 27 July 2019 and 4 October 2020.
- Courts heard specific incidents included a nearly five‑hour spill at Broadstairs caused by a computer control fault on 16 February 2021 and large discharges on 16–17 June 2021 that led Thanet council to close 11 bathing waters for a week.
- Prosecutors said some discharges were 'unscreened', leaving solid waste and debris on beaches, and Thanet officials warned the pollution damaged the area’s tourism‑dependent economy where about 20% of jobs relate to tourism.
- Southern Water told the court it has new leadership since 2022 and has invested about £38 million at Margate to prevent recurrence, but judges and prosecutors cited a wider record of past convictions and said the case underlines continued regulatory scrutiny and reputational risk.
