Anglian Water is set to pay a £62.8 million enforcement package after UK water regulator Ofwat found serious failings in its wastewater treatment and management systems. The investigation uncovered excessive storm overflow spills, linked to poor maintenance, underinvestment in key assets, and non-compliance with the Urban Waste Water Treatment Regulation.
This action forms part of a wider, sector-wide investigation launched in 2022. Similar penalties have already been issued to South West Water, Thames Water, Northumbrian Water, and Yorkshire Water. With total enforcement packages now exceeding £184 million, the regulator is sending a clear message: corporate sustainability is inseparable from environmental performance and infrastructure accountability.

Redirecting fines into the community and environmental impact
Anglian Water has accepted the findings and proposed a redress package aimed at restoring trust. Of the £62.8 million enforcement package, £57 million will be used to deliver Excess Flow Management Plans – localised initiatives to reduce overflows and optimise wastewater systems in at least eight catchments across the East of England.
This includes measures such as:
- Installing sustainable drainage solutions (SuDS)
- Upgrading community-owned infrastructure, contributing to flooding
- Remediation work to bring storm overflows back into compliance
In addition, a ringfenced £5.8 million Community Fund will be allocated to environmental and community initiatives near Anglian Water’s storm overflow sites, managed in partnership with Cambridge Community Foundation. This aligns with emerging expectations for corporate water stewardship to deliver value not just to shareholders, but to the communities and ecosystems most affected by operational impacts.
A broader test of corporate water stewardship
While this redress is welcomed, the situation highlights a deeper issue: even well-resourced utilities can face long-term regulatory, reputational, and environmental costs when sustainability is not embedded into operational and capital planning.
For companies in water-intensive sectors, the Anglian Water case underscores the need to treat water stewardship as a central component of corporate sustainability strategy. This requires cross-functional alignment, proactive risk management, and sustained investment in resilient, future-fit wastewater infrastructure.
CEO Mark Thurston confirmed plans to invest £1 billion by 2030 in storm tanks, nature-based solutions, advanced monitoring systems, and drainage resilience, part of a wider £11 billion business plan. However, as Ofwat emphasised, these investments must be underpinned by robust systems, strong governance, and a culture of accountability to deliver meaningful, lasting change.
Conclusion: From penalties to proactive investment
The Anglian Water case underscores a growing reality for all businesses: poor environmental management is now inseparable from operational and financial risk. Reputational damage, regulatory penalties, and stakeholder scrutiny are now material risks that demand attention at the board level.
Sustainability isn’t a compliance exercise; it’s a strategic capability that influences resilience, profitability, and long-term growth. Organisations that embed it into their planning, operations, and culture are not only managing risk – they’re positioning themselves to lead. At the Institute of Sustainability Studies, we support companies in building this capability from within.
Our focus is on practical, accredited education that empowers teams to make informed decisions, drive measurable progress, and respond with confidence to shifting expectations. In a landscape shaped by complexity and accountability, businesses that act early and invest wisely won’t just avoid the costs of falling short – they’ll realise the value of getting it right.
