New report shows several water companies must improve environmental performance


The Environment Agency has released its annual report on the environmental performance of England’s water and sewerage companies, showing that four out of nine companies are falling short of expected standards.

The annual report rates each company in England from 1 star to 4 stars, based on a range of measures including serious pollution incidents, pollution per km of sewer pipes and compliance with permits.

The report found that:

  • Severn Trent and Wessex Water achieved the highest level of performance with 4 star (industry-leading)
  • Thames, United Utilities and Yorkshire Water are rated as 3 star (good)
  • Anglian, Northumbrian and South West Water are rated as 2 star (requiring improvement)
  • Southern Water is the first company to be rated as 1 star (poor) since 2015

Ian McAulay, Southern Water CEO, commented the assessment: “As would rightly be expected we are extremely disappointed to have fallen in the ratings awarded in this year’s Environmental Performance Assessment.

“We are already taking bold steps to set our pollution record straight.

“We invested an additional £3.2 million during 2019–20 to improve our ability to find and fix leaks alongside an additional £54 million to improve pollution performance.

“Southern Water is a company in transformation and last month we announced our Pollution Incident Reduction Plan, which was shared with the Environment Agency following months of work.

“It sets out a plan to reduce pollution incidents to 80 per year by 2025, and zero pollution incidents by 2040.

“We are also fully confident this plan and future iterations will allow us to reduce the number of pollutions incidents in the imminent future.”

While the number of serious water quality pollution incidents from water company sewerage and clean water assets has plateaued – with a slight improvement to 52 compared to 56 in 2018 – the total number of pollution incidents has increased.

In light of these results, both the Environment Secretary George Eustice and the Chair of the Environment Agency, Emma Howard Boyd, will be holding meetings with all underperforming companies to discuss improving their performance.

Ms Boyd commented: “We cannot transform water quality in the way we all want if water companies’ environmental performance continues to backslide.

“Severn Trent and Wessex Water show high performance is possible, and United Utilities were the best-performing for serious pollution incidents, but the evidence suggests that the rest of the sector isn’t listening.

“I will be meeting water company chairs in the coming weeks to make it clear that we expect much more.

“This includes developing, publishing and implementing specific plans by the end of this year to reduce pollution incidents.

“We will closely follow the delivery of these plans and will apply tough regulation to ensure companies stick by them.”

Other action being taken includes:

  • Pollution Incident Reduction Plans (PIRPs) – The EA has requested all water companies develop, publish and implement specific plans to reduce the pollution incidents by the end of this year, which the EA can scrutinise and monitor, challenging companies where needed to ensure they deliver.
  • Penalties and prosecutions – The EA has brought 44 prosecutions against water companies in the last five years, securing fines of £34 million. £7.9 million has also been donated to environmental and wildlife trusts organisations in the same period through enforcement undertakings, a voluntary agreement which will include a donation to environmental charities to restore any harm done. The EA will also continue to prosecute water companies which fail to uphold the law or cause serious environmental harm.
  • Storm Overflows Taskforce – A new Taskforce was set up between Defra, the EA, Ofwat and Water UK earlier this year which will set out proposals to reduce the frequency and volumes of sewage discharged into our water courses.

Emma Clancy, chief executive of the Consumer Council for Water (CCW), commented on the findings: “No water company should need reminding that consumers see protecting the environment as a vital part of the water industry’s day job and not treated like an optional extra.

“Whenever a water company pollutes a river, stream or the sea it damages not just the environment but the trust of its customers who pay it in good faith to protect it.

“We want to see all water companies keeping their customers regularly informed of their plans and progress in reducing pollution incidents.”

Marcus Rink, Chief Inspector of the Drinking Water Inspectorate, commented: “Protecting and improving our natural waters enhances the environment we live in as well as improving and managing the catchments for our drinking water.

“The combined benefit of protecting the environment ultimately reduces risks to our drinking water resources and minimises the energy and chemicals we need to expend in treatment, securing a better future for all.

“I encourage companies to improve environmental performance, thereby enhancing the wider synergies of water supply.”

The Environment Agency has been clear it will continue to take whatever action is needed to protect water.

Its work with water companies and industry in the last two decades means there is now 60% less phosphate, 70% less ammonia, 50% less cadmium and mercury, and significantly lower levels of copper and lead in waste water.

Environment Minister Rebecca Pow, along with representatives from EA and Ofwat, also met with water company CEOs on 8 September and reiterated the need for improvement specifically on storm overflows, chalk streams and leakage.

Rachel Fletcher, Chief Executive at Ofwat, added: “We expect companies to deliver more for customers, society and the environment, so we are disappointed to see an increase in the number of pollution incidents.

“At the same time it is good to see two companies, Severn Trent and Wessex Water, improving their performance to reach the highest EPA score, and to see United Utilities demonstrating that the goal of zero serious pollution incidents can be achieved.

“We expect others to learn from such successes, and our recent price review has also set tougher new performance targets for companies to further reduce pollution incidents.

“We all have our part to play, and we will continue to work with government, Environment Agency and the industry to ensure that the sector as a whole can step up and leave the environment in a better place than we find it now.”
