Welsh Water singled out for criticism by Ofwat amid pollution incidents

The Welsh Liberal Democrats have called for stricter limits on pollution after Ofwat named Welsh Water among the six worst-performing water firms.

The regulator singled out the not for profit Welsh company as well as Northumbrian Water, Southern Water, South West Water, Thames Water and Yorkshire Water, saying it is “deeply concerned by those that are lagging behind expectations”.

Welsh Water performed particularly poorly in drinking water standards, water supply interruptions and water quality. The company also failed to meet its pollution incidents target, Ofwat said.

Ofwat chief executive David Black said: “In too many areas, water and wastewater companies are falling short when it comes to looking after customers, the environment and their own financial resilience. We are clear: these companies need to address this unacceptable performance as a matter of urgency.”

Two weeks ago, an analysis of Environment Agency data by the Welsh Liberal Democrats revealed that Welsh Water has dumped sewage onto Blue Flag beaches 579 times, lasting 6,757 hours.

Commenting Welsh Liberal Democrat Leader Jane Dodds said: “These are yet more disappointing results for Welsh Water yet the company has continued to give out large bonuses to its executives despite these poor results, supposedly being a non-profit and the ongoing sewage dumping scandal.

“These bonuses that are rewarding failure should be banned immediately and the finances redirected directly into improving infrastructure across the network.

“The Conservatives have failed to legislate against sewage dumping at a Westminster level at the same time as failing to give Ofwat any real regulatory teeth.

“We also need to see the Welsh Labour Government act to ensure that Natural Resources Wales has the funding and staffing it needs to do its job properly and that legislation is strengthened so that Water Companies can be more strictly regulated.”


The firms must now explain what has led to their poor performance and present a clear action plan to turn this around, Ofwat said, as it published its annual assessment of company operational performance and financial resilience.

Most companies had “again failed to clearly explain the link between their dividend decisions and payments with performance delivery for customers”, Ofwat said.

It added: “In particular, both Northumbrian Water and Portsmouth Water fell short of our expectations when considered in the context of the level of dividend they paid, which was significantly higher than our base expectations, and their relative financial resilience.”

The report said there has been encouraging progress on leakage, which is now at its lowest level since privatisation.

However, the number of serious pollution incidents increased, with Ofwat revealing earlier this week that water firms are failing to invest as much as they promised to fix their networks, including improving sewage treatment and reducing spills into the environment.

Between 2020 and 2022, 14 companies underspent their budget on improving their water network and eight companies underspent their budget for improving their wastewater network.

Affinity Water and Northumbrian Water spent just 47% and 48% of their water enhancement allowance respectively, and Yorkshire Water and South West Water spent just 20% and 39% of their wastewater enhancement allowance respectively.

The main areas of underspending across both categories included drought resilience, improvements to sewage treatment works, improvements to storm tank capacity and reducing spill frequency.

Ofwat sets allowances for how much companies can charge households to then invest over the price control period, to maintain and improve its water network.

‘Poor performance’

Last month, campaign group Surfers Against Sewage (SAS) claimed that water companies had released raw sewage into UK rivers and seas almost 150 times during dry weather – despite being told to do so only when there is heavy rainfall.

So-called “dry spills” occurred at least 146 times “at a conservative estimate” when there was no rain recorded between October last year and September, SAS said.

The spills are intended to occur only during times of exceptional rainfall to help the sewage network cope, with releases at other times a potential breach of water firms’ permits.

Over the same period, SAS issued 9,216 sewage pollution alerts via its Safer Seas & Rivers Service, which covers more than 450 beach and river spots across the UK and is designed to help the public make informed decisions about where and when they swim, surf or paddle.

A quarter (2,053) were during the 2022 bathing season and 39% of sickness cases reported to SAS correlated with the alerts, the group said.

Ofwat chief executive David Black said: “For some companies, poor performance has become the norm. This cannot go on. We are requiring the worst performers, including Thames Water and Southern Water, to return around £120 million to customers.

“Separate from today’s reports, we are taking enforcement action on wastewater treatment works compliance, well as consulting on licence changes that will help us drive through the transformation needed across the water industry.”


Water UK chief executive Christine McGourty said: “There are areas of good performance right across the sector, but this report clearly shows there’s more to do for water and wastewater companies to meet the stretching targets of the regulators, as well as the high expectations of the public.

“It’s good to see that nearly every company has met its target on leakage reduction with an ambitious industry-wide plan in place to cut leaks by 50% by 2050.

“Water companies will continue to work with Government and the regulators to ensure we enable the levels of investment needed to improve our infrastructure and protect the environment, while maintaining value for money for customers.”

Emma Clancy, chief executive of the Consumer Council for Water (CCW), said: “The cost-of-living crisis means households have enough to worry about without water companies adding to their concerns through poor customer service or the devastation of seeing their home flooded with sewage.

“Water is an essential service that should be reliable, safe and affordable for everyone but some companies are falling short of meeting their customers’ expectations.”

“Many people are irritated by leakage so the industry needs to stretch itself further, with far more focus on tackling visible leaks quickly, while keeping their customers regularly informed of what they are doing and the impact it’s having.”

Possible mitigating factor in DCWW’s defence: During Covid, DCWW honoured its pledge to not allow any customer to be in water poverty. All non-essential works were cancelled to cover losses from an inability to pay bills and it may be they are still recovering from that.
In the narrow scope of the OFWAT report their breaches look damning. But taken in the round that fact might go some way to explaining why.

The Llanelli Cockle fishermen took the UK to the EU Court of Justice in 2012 the judgement of the Court 2017 In Case C-502/15. In 2018 a presentation published on the net disclosed that millions of tons of sewage were discharged annually into the Loughor Estuary from 31 CSO’s and treatment works. This is happening all around the Welsh Coast and into Welsh Rivers however unlike some other Water Companies, there has been very little enforcement action taken against the Water Company. Why is there no public inquiry into this mess.

Yes it does, possibly because it’s a drain in Vancouver, Canada:

But, but, it’s ‘not for profit’ (unless you’re one of its highly paid executives) and Welsh the middle class splutters!

Why, when the business is doing so badly in tere od leak prevention and waste discharges are the CEO and directors getting bonuses? How can we the citizens of Cymru for whom this company is supposed to work bring pressure to bear? Surely sewage leak = lost bonus. That would perhaps get things moving.
