Yorkshire Water has been named as one of the five water companies, Ofwat, the body responsible for economic regulation of the privatised water and sewerage industry in England, is investing over wastewater treatment works.
Anglian Water, Northumbrian Water, Thames Water, Wessex Water and Yorkshire Water have been served formal notices to gather further information for enforcement purposes.
This follows an analysis of the information water and wastewater companies were asked to submit to Ofwat in late December about how many of their sewage treatment works might not be meeting requirements in their environmental permits, and what companies are doing to resolve that.
Concern about aspects of these five companies’ submissions has prompted Ofwat’s current focus. However, all water and sewerage companies in England and Wales remain subject to the ongoing investigation as Ofwat continues its review of the information it has gathered.
Ofwat will keep the enforcement cases under review, and the companies in focus may change as new information comes to light.
The five companies are targeted because the information they provided in December raised one or more of the following concerns:
- it reported a significant number of wastewater treatment works that the company considers might not be compliant with its environmental permits.
- it raised concerns about how overall the company manages its compliance with its environmental obligations.
- it didn’t sufficiently show how the company have established whether its treatment works are meeting the requirements of its environmental permits, and so we need further information for our assessment.
In their December responses to Ofwat, all but one company reported having had some treatment works that were potentially non-compliant with the flow to full treatment (FFT) requirements of their environmental permits.
Many companies set out the steps they have taken or are taking to bring those treatment works back into compliance. However, some companies did not offer sufficient assurances that they monitor and understand the compliance of their treatment works, or the root causes of any non-compliance.
David Black, Ofwat interim Chief Executive, said: “The data that emerged at the end of last year suggested widespread shortcomings in how water companies were running sewage treatment works. The first phase of our investigation suggests those concerns are credible.
“We have identified shortcomings in most water and wastewater companies and are continuing to investigate. But we have already seen enough in five companies to cause serious concern and warrant us taking further action.
“We will now dig deeper into what these five companies have been doing, with the prospect of formal enforcement against them if we find they are failing on obligations Ofwat enforces.
“We will have further questions for all companies on this. In the meantime, we expect them to make quick progress in addressing any potential non-compliance they might have, whilst strengthening how they manage their environmental obligations as a whole.”
A spokesperson for Yorkshire Water, said: “We take our commitment to care for the environment very seriously. We will of course be cooperating fully with the investigation and it would be inappropriate to comment any further while it is ongoing.”
Ofwat’s enforcement powers can see the regulator fine companies up to 10% of their annual turnover.
