A wave of failures
In recent months, Anglian Water—the supplier responsible for water and sewage services across eastern England—has found itself at the centre of a major scandal. In May 2025, the company was slapped with a record £1.42 million fine after investigators discovered unauthorised plastic-based coatings in several drinking-water tanks, which broke down into flakes and powder affecting 1.3 million people between June and December 2021 (theguardian.com). The Drinking Water Inspectorate (DWI) labelled the incident “scandalous and a complete disgrace” (reuters.com).
At the same time, environmental groups revealed that Anglian Water had been reporting hundreds of pollution tests at sewage plants during periods of “no flow,” meaning these tests were not actually carried out—over 6,000 instances since 2015, including 496 in 2024 alone (theguardian.com). Critics argue this self-monitoring regime enabled the company to “mark its own homework,” avoiding scrutiny until regulators tightened the rules (theguardian.com).
Fenland in the firing line
This controversy hits particularly close to home for Fenland. The district, nestled in the heart of East Cambridgeshire, relies heavily on small rural treatment works—all part of Anglian Water’s vast network. The sheer number of no-flow events recorded in rural plants is especially concerning for Fenland residents, as weaker scrutiny could mask failures to meet environmental standards .
Health and environmental worries
Although Anglian Water maintains that the drinking-water contamination posed a “very low risk” to customers (anglianwater.co.uk), the episode has still shaken public confidence. Anglian claims to have resolved the issues, but the damage to trust remains. Moreover, the no-flow incidents suggest that sewage treatment compliance might often be overstated. Given Fenland’s sensitive watercourses—streams, drains and rivers integral to agriculture and wildlife—this lack of transparency could conceal harmful pollution events.
Regulatory and financial fallout
Anglian Water is now embroiled in more than 50 criminal investigations connected to sewage dumping across the region (theguardian.com). It has also slipped into the firing line of a government-wide reform of the privatised water sector, which includes ban on bonuses for executives and tougher environmental performance mandates (thetimes.co.uk).
For Fenland households, this may mean increased vigilance over local water quality, and possibly higher bills—Anglian Water increased average household charges from £527 to £626 per annum, a 19% rise in April 2025 (news.sky.com).
What local residents should look out for
- Water quality alerts: Keep an eye on DWI or local authority notices regarding tap-water safety.
- Environmental reports: Regularly review Environment Agency data for pollution incidents in local rivers and drains.
- Local campaigning: Engage with community or environmental groups keeping watch on sewage works and water systems in Fenland.
The path ahead
Anglian Water apologised and says it has “invested significantly” to improve its compliance and monitoring procedures (anglianwater.co.uk). Meanwhile, the government is proceeding with a review that could transform water-industry regulation, including mandating independent testing and restricting bonuses for environmental violators .
For Fenland, the scandal serves as a crucial reminder: rural water infrastructure must not be overlooked. Ensuring transparency and accountability now is vital—before the next crisis.
