Contribution
I am happy to take that on board and back to the team for further discussion.
I turn to Amendment 40, also in the name of the noble Lord, Lord Cromwell, and supported by the noble Baroness, Lady Jones of Moulsecoomb. I thank him for proposing it, as the Government agree that it is important that water companies make information about emergency overflow discharges as easy to access as possible.
Clause 3 explicitly states that information on discharges from emergency overflows will need to be both readily accessible and understandable to the public. That duty will be enforceable by Ofwat, which will be able to access the underpinning raw data from emergency overflows to inform its enforcement responsibilities under the Water Industry Act.
Water companies have already begun to publish information on storm overflow discharges in near real time, ahead of the Water Industry Act duty coming into force in January next year. Furthermore, Water UK, in collaboration with water companies, is shortly due to publish a new centralised map of storm overflows—as referred to by the noble Lord from our discussions—which is designed to present real-time discharge data from all storm overflows in England on one website. I am sure that he will be delighted to hear that we are making good progress on this. The Minister for Water received a demonstration of the website only yesterday, and the Government understand that it is due to be published shortly.
A similar approach is intended to be followed for monitoring data for emergency overflows to meet Clause 3 requirements. In addition, if needed, guidance could be issued from the Government or the regulator to the sector to further support the implementation of the emergency overflow publishing duty. Therefore, since the industry is already planning to centralise data on sewage discharges on one website, the Government do not believe that an amendment to mandate publication on a centralised website is necessary.
The noble Lord asked a number of very specific questions. If I have not answered any of them, I am happy to come back to him in writing with more detail.
Amendment 41 is in the name of the noble Duke, the Duke of Wellington. I thank him for raising this important issue. The Government are clear that emergency overflows should be used only as an absolute last resort. We are talking about emergency overflows here, not storm overflows. Emergency overflows are different from storm overflows. They operate in response to an emergency event at a sewage pumping station, whereas storm overflows are designed to operate in combined sewer systems during heavy storm events. Discharges from emergency overflows should therefore only occur in much more limited circumstances.
As previously explained, environmental permits for emergency overflows already require companies to put in place strict protection measures to prevent, as far as possible, discharges due to power failure. That can include back-up generators or duplicate power supplies.
The Environment Agency will consider enforcement action if a company operates an emergency overflow and it can be proven that the discharge could have been avoided if the company had complied with the protection measures set out in its permits. Electrical power failure is an acceptable reason to discharge only when it is fully—I repeat, fully—outside the water company’s control and not due to any failure on its part to maintain protection measures.
The unintended impact of the amendment could be that we fail to provide for discharges that are outside a company’s control and that are necessary to protect upstream homes from flooding—for example, if a back-up generator failed or did not last long enough. For these reasons, we do not believe this amendment is necessary and are concerned about the unintended consequences.
Having said that, I appreciate that the noble Duke feels strongly on this point, so I extend an invitation to him that I hope he will take me up on. I offer him to join me on a visit to see some of the overflows in person, to enable him to look at the varied scale and types of infrastructure and protections that are already in place, to help him understand and, I hope, to put his mind at rest. I am sure that the noble Duke has never had an invitation from a noble Baroness to look at a sewage plant before and that this is an exciting first for him.
I once again thank noble Lords for their constructive engagement on the important matters of data transparency across water industry monitoring networks and the permitting of emergency overflows.
