South West Water Fined £1.8 Million for Brixham Cryptosporidium Outbreak

South West Water has been fined a record £1.853 million after cryptosporidium contaminated the drinking water supply in Brixham, Devon, during May 2024. Exeter Magistrates' Court imposed the penalty following a prosecution by the Drinking Water Inspectorate (DWI).

The utility firm pleaded guilty to supplying water unfit for human consumption, issuing a "full and unreserved apology". The incident led to over 140 confirmed cases of sickness and diarrhoea, with four individuals requiring hospitalisation. Judge Stuart Smith described the event as "a major public health incident" with "wide-ranging and profound" harm, noting the "systemic failure of governance" regarding air valve monitoring.

The contamination, traced to animal faeces entering the supply via a faulty air valve on agricultural land, resulted in a 54-day boil water notice for some 17,000 homes and businesses. The judge acknowledged South West Water's rapid response and financial remediation efforts, reducing the initial fine by a third due to the early guilty plea.

Keith Haslett, chief executive of Pennon Group, South West Water's owner, stated the company "must learn lessons from this incident". However, South Devon MP Caroline Voaden criticised the fine as insufficient, arguing it does not reflect the severity of the contamination or its impact on public health and the local economy.

Victim statements presented in court detailed severe symptoms, including prolonged illness, hospitalisation, and significant disruption to daily life, particularly impacting local businesses during what should have been a peak tourist season.
