Anglian Water has been fined £1.6 million following an Environment Agency prosecution over sewage pollution affecting almost 14 kilometres of the River Brain in Essex.
The Environment Agency announced the penalty on 16 October 2026, following a court hearing on 15 October. The pollution occurred between April and June 2022 and was traced to the company's Braintree Water Recycling Centre.
Faulty valve and ignored alarms
According to the Environment Agency, a faulty valve allowed inadequately treated sewage and sludge to enter the river. Alarms warning of the discharges were ignored, and failures in communication and local management contributed to the incidents.
Monitoring recorded ammonia concentrations at their highest levels in the River Brain for a decade. Investigators said the effects extended along nearly 14 kilometres of watercourse between Braintree and Witham.
Court penalty and regulator response
The Environment Agency prosecuted the company over discharges outside its environmental permit and failure to comply with permit conditions. The regulator reported a £1.6 million fine, plus £27,334 in costs and a £190 surcharge.
Environment Secretary Angela Eagle criticised the company's response and said stronger regulation and enforcement were needed to protect waterways. The Environment Agency said the incidents reflected organisational failures to recognise and act on warning signs.
Anglian Water apologises
In its own statement, Anglian Water acknowledged that its procedures fell below its standards, apologised for the effect on the River Brain and described changes to leadership, monitoring and operational processes since 2022. The company also pointed to its investment programme for 2025–2030.
The fine concerns pollution in 2022, not a newly occurring discharge in October 2026. The company’s acknowledgement should not be confused with evidence that the river has fully recovered.
