Big fines for water firms as Ofwat imposed penalties of £168 million in relation to failure to manage waste water at three companies.

Ofwat has today (6 August 2024) proposed that three water companies will be fined a total of £168m for failing to manage their wastewater treatment works and networks, as part of the first batch of outcomes from its biggest ever investigation.

Water companies fined

The penalties proposed for consultation will see Thames Water fined £104m, Yorkshire Water fined £47m and Northumbrian Water fined £17m.

The penalties relate to their management of wastewater treatment works and wider sewer networks including their operation of storm overflows. These are designed to release water in exceptional circumstances, when the sewerage system is at risk of being overwhelmed, such as during unusually heavy downpours or snowfall, to prevent sewage flooding into people’s homes.

Big fines for water firms’ failures

Ofwat has found that all three firms have:

• Failed to ensure that discharges of untreated wastewater from storm overflows occur only in exceptional circumstances which has resulted in harm to the environment and their customers.
• Shown a strong correlation between high spill levels and operational issues at wastewater treatment sites which points to these companies not having properly operated and maintained their wastewater treatment works.
• Failed to upgrade assets, where necessary, to ensure they meet the changing needs of the local area they serve.
• Been slow to understand the scope of their obligations relating to limiting pollution from storm overflows and failed to ensure that they had in place the necessary information, processes and oversight to enable them to properly comply with those requirements.

However, the scale of the breaches Ofwat has found, differs between each of the wastewater companies.  Investigations by the regulator found that:

• Thames Water had 67% of its wastewater treatment works with FFT permits found to have capacity and operational issues. 16% of its storm overflows associated with its wastewater treatment works were found to be in breach.
• Yorkshire Water had 16% of its wastewater treatment works with FFT permits found to have capacity or operational problems. 45% of its storm overflows associated with its wastewater treatment works were found to be in breach.
• Northumbrian Water had 3% of its wastewater treatment works with FFT permits found to have capacity or operational problems. 9% of its storm overflows associated with its wastewater treatment works were found to be in breach.

Therefore, in addition to the proposed big fines for water firms, Ofwat is also consulting on proposed enforcement orders which will require each company to rectify the problems Ofwat has identified to ensure they comply with their legal and regulatory obligations.

Companies will not be able to recover the money for any proposed penalties from customers and Ofwat will ensure that customers are not charged twice where additional maintenance is required.

Ofwat’s Chief Executive David Black said:

Ofwat has uncovered a catalogue of failure by Thames Water, Yorkshire Water and Northumbrian Water in how they ran their sewage works and this resulted in excessive spills from storm overflows. Our investigation has shown how they routinely released sewage into our rivers and seas, rather than ensuring that this only happens in exceptional circumstances as the law intends.

The level of penalties we intend to impose signals both the severity of the failings and our determination to take action to ensure water companies do more to deliver cleaner rivers and seas.

These companies need to move at pace to put things right and meet their obligations to protect customers and the environment. They also need to transform how they look after the environment and to focus on doing better in the future.

Looking to the future we want transform companies’ performance under our new price control that starts in April next year, so we reduce spills from sewage overflows by 44 per cent by 2030 compared to 2021 levels.

These proposed findings are the first three cases Ofwat has open in its wider investigation to reach this stage. This investigation is a priority for Ofwat, and it will continue to work as quickly as possible on the eight further cases.

Enforcement notices have been issued to the three water companies fined:

• Enforcement case in Thames Water’s management of its sewage treatment works and sewerage networks
• Enforcement case in Yorkshire Water’s management of its sewage treatment works and sewerage networks
• Enforcement case in Northumbrian Water’s management of its sewage treatment works and sewerage networks

Ofwat can impose big fines on water firms, the value of which can be up to 10% of relevant turnover. For each company, the fines applied in this investigation equates to (i) Thames Water – 9% of turnover, (ii) Yorkshire Water – 7% of turnover, and (iii) Northumbrian Water – 5% of turnover.

The big fines for water firms were issued under Section 22A Water Industry Act 1991 provides details of how financial penalties are calculated and imposed with accompanying guidance.

These penalties are separate to the commitments that have been set out as part of PR24 draft determinations for all wastewater companies which will see £9.5bn overall enhancement expenditure for storm overflow improvements to meet their new performance commitment targets.

Big fines for water firms are likely to continue when the sector is facing unprecedented challenges, with climate change, population growth, urbanisation, and emerging pollutants all putting pressure on the environment across England and Wales. To help address these challenges, a new Evidence and Performance team has been created within Ofwat to enhance Ofwat’s environmental assessment and monitoring capabilities.

A court judgment handed down by the Supreme Court this week could open the floodgates to claims against water companies.  In The Manchester Ship Canal Company Limited v United Utilities Water Limited No 2 [2024] UKSC 22, the Supreme Court Justices ruled that private individuals can bring claims in nuisance or trespass against water companies for pollution.

Background to Court Judgment

This appeal forms part of long-running litigation about discharges of foul water contaminated with untreated sewage into the Manchester Ship Canal. The Supreme Court is asked to decide whether the owner of the beds and banks of the canal, the Manchester Ship Canal Company Ltd (“the Canal Company”), can bring a claim in nuisance or trespass when the canal is polluted by discharges of foul water from outfalls maintained by the statutory sewerage undertaker, United Utilities Water Ltd (“United Utilities”). 

United Utilities is the statutory sewerage undertaker for the North West of England. Its sewerage network includes around 100 outfalls from which material emanating from sewers, sewage treatment works and pumping stations is discharged into the canal. When it is operating within its hydraulic capacity, the discharges are of surface water or treated effluent, but when the system’s hydraulic capacity is exceeded at least some of the outfalls discharge foul water into the canal. There is no suggestion that these polluting discharges are caused by negligence or deliberate wrongdoing on the part of United Utilities. However, they could be avoided if United Utilities invested in improved infrastructure and treatment processes.

The Canal Company threatened to bring a claim against United Utilities for trespass and nuisance. In response, United Utilities asked the court to make a declaration that the Canal Company had no right of action. The court was not asked to decide whether the Canal Company’s claim would be successful on the relevant facts. Rather, the question was whether the claim would be inconsistent with and therefore barred by the statutory scheme for regulating sewerage established by the Water Industry Act 1991 (“the 1991 Act”).  

The High Court judge agreed to make the declaration requested by United Utilities. His decision was upheld by the Court of Appeal. The implication of these judgments is that no owner of a canal (or other watercourse or body of water) can bring a claim based on nuisance or trespass against a sewerage undertaker in respect of polluting discharges into the water, unless the sewerage undertaker is guilty of negligence or deliberate wrongdoing. A claim of this kind would be prevented even if the polluting discharges were frequent and had significant and damaging effects on the owner’s commercial or other interests, or on its ability to enjoy its property. The Canal Company appeals to the Supreme Court.

Court Judgment

The Supreme Court unanimously allowed the Canal Company’s appeal. The Court held that the 1991 Act does not prevent the Canal Company from bringing a claim in nuisance or trespass when the canal is polluted by discharges of foul water from United Utilities’ outfalls, even if there has been no negligence or deliberate misconduct. Lord Reed and Lord Hodge give a joint judgment with which the other members of the Court agree. 

Reasons for the Decision

The starting point is that the owner of a canal or other watercourse has a property right in the watercourse, including a right to preserve the quality of the water. That right is protected by the common law. The discharge of polluting effluent into a privately-owned watercourse is an actionable nuisance at common law if the pollution interferes with the owner’s use or enjoyment of its property. The Supreme Court was, therefore, asked to decide whether the 1991 Act excludes common law rights of action in nuisance and trespass. This is a question of statutory interpretation. 

Statutory Powers

A body which exercises statutory powers, such as a sewerage undertaker, is liable in the same way as any other person if it is responsible for a nuisance, trespass or other tort, unless either it: (i) is acting within its statutory powers, or (ii) has been granted some statutory immunity from suit. If a sewerage undertaker interferes with a person’s rights, it is therefore necessary to distinguish between interferences which Parliament has authorised, which are lawful, and interferences which Parliament has not authorised, which are unlawful. When drawing this distinction, two principles are relevant. First, a person’s rights to the peaceful enjoyment of its property and to access the courts are protected by both the common law and the Human Rights Act 1998.

The principle of legality holds that fundamental rights cannot be overridden by general or ambiguous words. A statute will, therefore, only authorise what would otherwise be an unlawful interference with property rights or deprive a person of the right to bring a legal claim, if this is clear from or a necessary implication of the express language used by Parliament. Secondly, Parliament will not be taken to have intended that statutory powers should be exercised, or duties performed, in a way which interferes with private rights, unless the interference is inevitable. 

The 1991 Act does not expressly authorise United Utilities to cause a nuisance or to trespass by discharging foul water through the outfalls into the canal. United Utilities’ entitlement to use the outfalls derives from section 116 of the 1991 Act. However, this entitlement is subject to a number of statutory protections for watercourses. Section 117(5) provides that nothing in section 116 (or the other relevant sewerage provisions of the 1991 Act) authorises a sewerage undertaker to use a sewer, drain or outfall to convey foul water into a watercourse. Sewerage undertakers therefore do not have statutory authority to discharge untreated sewage into watercourses. Section 117(6) prevents a sewerage undertaker from carrying out its functions under the relevant sewerage provisions so as to create a nuisance. Section 94(4) makes it clear that the common law remedies for nuisance – such as an injunction or damages – are available in addition to any remedy available by virtue of section 94. Section 186(3) further protects the owners of watercourses, and other rights-holders, by stating that nothing in the relevant sewerage provisions authorises a sewerage undertaker to damage a watercourse, or the quality of the water in it, without consent.

Unauthorised Pollution

The Court judgment concludes that the polluting discharges similarly cannot be regarded as having been impliedly authorised by Parliament, since they are not an inevitable consequence of a sewerage undertaker’s performance of its statutory powers and duties. In the present case, the discharges could be avoided if United Utilities invested in improved infrastructure and treatment processes.

If Parliament has not authorised an interference with private law rights, it would normally follow that a claimant can enforce those rights at common law. Furthermore, since sections 117(5) and 186(3) limit the authority conferred on sewerage undertakers by the 1991 Act, there must be a common law remedy where those limits are exceeded: otherwise, the sections would have no purpose. 

Marcic Case

United Utilities argues that the Canal Company has no cause of action because the only way to avoid the discharges of foul water into the canal would be to construct new sewerage infrastructure. It relies on the House of Lords’ decision in Marcic v Thames Water Utilities Ltd [2003] UKHL 66 (“Marcic”), which it says established that Parliament’s intention was that the construction of new sewerage infrastructure should be a matter for the Secretary of State or the regulator, the Water Services Regulation Authority (known as “Ofwat”), not the courts. 

In the Court judgment, the Supreme Court rejects this argument. There are a number of indications that Parliament did not intend the 1991 Act to exclude a claimant’s right to enforce its private property right in a watercourse. First, section 186(7) provides for arbitration where water quality has been damaged without consent, at the option of the party complaining. This strongly suggests that the complainant could alternatively choose to pursue a common law claim. 

Statutory Compensation

Secondly, section 180 of the 1991 Act gives effect to Schedule 12, which makes provision for statutory compensation. Compensation is available for damage caused by the authorised acts of sewerage undertakers, but not for damage caused by acts which are unauthorised, such as the discharges of foul water into the canal. This indicates that the victims of unauthorised damage retain their common law rights of action. Otherwise, they would be left without any remedy for the damage they have suffered, which would be anomalous. They would also be treated less favourably than the victims of authorised damage, which would be perverse. 

Thirdly, the Court judgment states that depriving the victims of a nuisance or trespass of their common law rights of action would be a substantial change to the law as it stood before the 1991 Act was enacted. It is unlikely that a change of this kind would have been made in a consolidation statute.

Consolidation acts are not designed to make substantive changes to the law, but rather to reorganise and restate the existing law so that it is clearer and easier to understand. Moreover, the Court judgment notes that since the 1991 Act is detailed and elaborate, it would be surprising if Parliament had left an important change in the law to be implied rather than stated expressly. In addition, the principle of legality holds that fundamental common law rights, such as a right of action to protect private property, are not to be taken to be overridden in the absence of express language or necessary implication.

In the Court judgment, the Justices noted that United Utilities relied on section 18, which empowers the Secretary of State and Ofwat to make enforcement orders for the purpose of securing compliance by sewerage undertakers with statutory and certain other requirements. These include the general duty in section 94, which requires sewerage undertakers to provide a sewerage system. Section 18(8) makes it clear that it is not possible to enforce these statutory and other requirements by bringing a claim at common law; an order under section 18 provides the only available remedy. However, this ouster only applies to causes of action that are based on a breach of a statutory or other requirement that is enforceable under section 18. If a sewerage undertaker does something (or fails to do something) which gives rise to an independent common law cause of action, for example, for nuisance or trespass, the 1991 Act does not prevent the courts from enforcing the claimant’s common law rights and awarding any available common law remedies.

The Supreme Court accepted that the regulatory scheme established by the 1991 Act, including the making of enforcement orders under section 18, might be disrupted if the court were to grant injunctions which required a sewerage undertaker to spend large sums on new infrastructure as a remedy for interferences with private property rights. The Court judgement goes on to say that might be so if such an injunction conflicted with the arrangements in the Act for the regulatory approval of capital expenditure and the charges imposed on the sewerage undertaker’s customers.

The Court judgment states however, this does not mean that common law rights of action are excluded in such a case. Instead, the courts may make an award in damages, both for past invasions of property rights and for future or repeated invasions of those rights. This would vindicate property rights in relation to watercourses until the sewerage undertaker is in a position, with Ofwat’s approval, to invest in a long-term solution. 

Court Judgment Distinguishes Marcic

The Supreme Court’s conclusion that the 1991 Act does not prevent the Canal Company from bringing a claim in nuisance or trespass when the canal is polluted by discharges of foul water from United Utilities’ outfalls can be reconciled with the decision in Marcic. That case can be distinguished, first, because it did not concern the limits on the authority conferred on sewerage undertakers by the 1991 Act set out in sections 117(5) and 186(3).

Secondly, the Court judgment states that the defendant sewerage undertaker had not created or adopted the relevant nuisance, as it has in the present case. Instead, it was said to be liable for continuing the nuisance by failing to take reasonable steps to avert it by constructing a new public sewer. An essential ingredient of the cause of action was therefore that the defendant was under a duty to build a new sewer, in accordance with section 94(1) of the 1991 Act. That duty could only be enforced by the Secretary of State or Ofwat under section 18, not by the courts.

In contrast, the Canal Company’s proposed claim against United Utilities is not based on a breach of section 94(1), or any other requirement enforceable under section 18, but rather on independent common law causes of action in trespass and nuisance.

Conclusion

The Court judgment is likely to encourage other groups and individuals to consider claims against water companies following pollution incidents.  The increased focus on pollution incidents involving water companies has resulted in a number of investigations by the regulator, the Environment Agency, responding to public concerns.  Campaign and pressure groups will also be pleased with the Court’s decision.
