United Utilities has been ordered to pay £517,000 to the Environment Agency (EA) following a series of sewage discharge breaches into the River Tame. The significant payment comes after a detailed investigation by the EA revealed three permit violations at the Ashton-under-Lyne wastewater treatment works. The incidents, which occurred due to a mechanical failure in a final settlement tank, led to a substantial amount of sludge and untreated wastewater entering the river, far exceeding permitted levels.
The Environment Agency confirmed that a sample taken on 2 August 2022 showed suspended solids at 940 mg/l, Biochemical Oxygen Demand (BOD) at 430 mg/l, and total iron at 32,200 µg/L. These figures drastically surpassed the permitted maximums of 30mg/l for suspended solids, 56 mg/l for BOD, and 8000 µg/L for total iron. United Utilities has since repaired the faulty tank and has also agreed to cover all of the EA's investigation costs.
This enforcement undertaking is part of a broader crackdown on pollution and poor performance across the water industry, with a record £8.5 million paid by water companies into environmental restoration projects nationwide – a 47% increase on the previous year. Andy Brown, Environment Agency Water Industry Regulation Manager, stated that while prosecution remains an option for serious offenders, enforcement undertakings allow companies to rectify their wrongdoings and directly fund environmental recovery. He emphasised that the £517,000 will be invested in the Tame catchment, aiming to deliver tangible benefits for local residents and wildlife.
The funds secured from United Utilities will be allocated to the Mersey Rivers Trust, an environmental charity dedicated to improving the health of rivers in the region. This approach allows for immediate environmental benefits without the need for potentially lengthy and uncertain court proceedings, complementing the EA's wider enforcement efforts against repeat offenders. In March, the Environment Agency reported completing over 10,000 inspections of water company assets in the past year, including 1,855 at United Utilities premises, to ensure compliance and proper operation.
While this particular incident relates to environmental damage, the broader context of water company performance and infrastructure directly impacts household finances. Increased investment in infrastructure, often driven by such enforcement actions, can sometimes translate into higher utility bills for consumers. For now, government support schemes like the Warm Home Discount and Universal Credit remain available for eligible households struggling with essential costs, including water bills. Organisations like Citizens Advice and MoneySavingExpert continue to offer guidance on managing utility expenses and understanding consumer rights regarding water services.
