The Parliamentary Under-Secretary of State for Environment, Food and Rural Affairs (Rebecca Pow)
It is a pleasure to be here with you this morning, Dame Angela, albeit with a very small crowd. I congratulate the hon. Member for Blaydon (Liz Twist) on securing the debate on this important issue. She painted a fine picture of her constituency—the River Tyne, the wonderful wildlife and the value that they have for local people, especially at this time. People now realise how important our river landscapes can be for our health and wellbeing. I thank her for bringing this subject to us, because water quality is dear to my heart. As the Environment Minister, I am doing a great deal of work on it, particularly on issues relating to sewage discharges, as I will explain. I hope she will see that I am putting this subject under the microscope in various ways.
We have been given a lot of information about the damaging impacts of uncontrolled sewage discharges into local rivers and streams. River health and the impact of sewer overflows is an absolute priority for me as the Environment Minister, and I am absolutely determined to take action on it. In my view, it has been overlooked for far too long, and it needs to rise right up the agenda. The debate gives me a great opportunity to talk about some of the related issues.
It is clear from what the hon. Member says that this issue is really important to local people, too—not just Surfers Against Sewage, which has gathered some really valuable data, including about the coast of the west country, where I come from. It has been working on this problem for years and should be commended for its work.
I will first describe some of the challenges that we face in resolving the problem of excessive sewage discharges. Without adequate treatment, wastewater discharges into our rivers can have serious impacts on the natural environment can cause long-lasting damage to the ecosystem. There is even a potential risk to human health—the hon. Member mentioned the water-borne bacteria and viruses—so effective treatment of wastewater at wastewater treatment works is vital.
Before wastewater reaches the treatment works, there are storm overflows within the sewerage system, which the hon. Member mentioned. Storm overflows were a design feature of Victorian sewers—they date back a very long way. They are still being used, and they remain an integral part of our infrastructure today. Many of our sewer systems are combined systems, wherein sewage is combined with rainwater, and following heavy and prolonged rain the capacity of those systems can be exceeded. When that happens, the storm overflows act as a relief valve to discharge excessive sewage, combined with rainwater, into our rivers and the sea. The idea is to protect properties from flooding and prevent the unpleasant backing up of sewage in the system into our streets and homes during heavy storms. Reliance is increasing on the storm overflows, however, largely due to escalating population growth and the consequent urban development, together with more frequent storms due to climate change and more frequent sudden weather events. All that is putting more pressure on our sewerage system and increasing the use of storm overflows.
Eliminating the harm from overflows will be challenging. It would involve disruption and high costs, which would impact on customers’ bills, but recognising the scale of the challenge is the first step towards addressing it. That is what the hon. Member has highlighted today, and that is what I am working on. We are fully committed to bringing at least three quarters of our waters closer to their natural state as soon as is practicable. That is why over £30 billion has been invested by the water industry since 1990 to protect the environment, covering improvements in sewage treatment and sewage overflows. As a result, we have seen improvements in our water quality over the years, as the hon. Member recognises. I am pleased to say that we have already achieved a 67% reduction in the amount of phosphorous in our rivers, and a 79% reduction in the amount of ammonia discharge from sewage treatment works since 1995.
Around 98% of our urban areas are now in compliance with the waste water treatment regulations’ standards, and in 2019, around 98% of our bathing waters met at least the minimum standard of the bathing water directive. Of those, 71% were classified as excellent, which is the highest water quality standard. Ofwat has also allocated £4.6 billion to water companies for the 2020-25 period to improve the water environment, and water companies plan to spend this money. Already, many have jointly committed £1.1 billion specifically to tackle storm overflows. That means that in every single water company region in England, investment is being made to address the problem we are discussing.
We are also making progress on understanding the scale of the problem. Water companies have installed event duration monitoring technology on the majority of storm overflows to improve our understanding of when storm overflows discharge sewage, and to trigger investigations and improvements when overflows operate too frequently. Increasingly, as the hon. Lady said, members of the public want to know more about their local environment and the pressures on it. We need to do more to make this information on storm overflows available to people in a consistent and user-friendly way. Indeed, I have received a great amount of correspondence regarding issues with storm overflows from people all around the country and MPs on every side of the House. However, we need the right data on that: water companies are already collecting lots of information and making it available, but I would like to see more progress in this area.
I have outlined a lot of the positives, but despite the improvements that have been put in place, I know that if we do not take further action reliance on storm overflows will increase, as will the number of sewage discharges from storm overflows across the country. We need to plan carefully, while also making sure that every step provides good value for money and leads to better outcomes—outcomes that mean more people enjoying our lakes and rivers, the sea, and the beautiful coast that the hon. Lady described. That is why, through the Government’s Environment Bill, I am placing a statutory obligation on sewerage companies to make drainage and sewerage management plans. A key objective of these plans is to ensure better management of sewage discharges into our waterways. Interestingly, water companies have had to have plans for their water—what comes out of taps—but not for sewage. Now, they will have to, and I think that is going to be really important in tackling this issue.
I recognise there is a strong desire to make even wider and faster progress. As such, last August, I set up the taskforce on storm overflows. consisting of Government regulators, water companies and environmental NGOs, in an attempt to bring together all the key stakeholders—the people who are affected by this issue and can influence this space. Our taskforce is developing clear proposals for achieving a transformation in sewage treatment and management for the benefit of us all. It will explore what actions could be taken, building on the findings of a research project, and will report back on what actions it believes ought to be taken. That will add a great deal more detail to what we want to do. I have also recently met with the CEOs of the water companies, basically to rattle their cage: to say we need more, and serious, action on tackling water quality, and that they must reduce the use of these overflows in extreme weather. In addition to that, the Environment Bill sets a legally binding duty on us to set targets, so we will be setting targets to do with water quality.
The hon. Lady touched on the private Member’s Bill of my right hon. Friend the Member for—
Rebecca Pow
I was going to say Ledbury—almost the right part of the world. I have had an awful lot of discussions with my right hon. Friend the Member for Ludlow (Philip Dunne) about that Bill. Obviously, dates are changing now for Friday sittings and private Members’ Bills, but I and my officials are continuing to discuss it with him. Of course, he raises some very good issues.
On wet wipes, and the “Bin the wipe” message, the hon. Member for Blaydon raises a great subject. I am fully supportive of her. The Department for Environment, Food and Rural Affairs has been working with the water industry and the wet wipe industry to improve labelling and consumer information, and even to come up with a “fine to flush” standard, so that if a manufacturer comes up with a wet wipe, to meet the standard of being okay to flush it has to be biodegradable and the manufacturer must prove that it does not do any damage to the environment. I fully support her on that, because we can do something about it.
The Environment Agency has a framework for all its monitoring. The hon. Lady is somewhat critical of the EA, but it has a legal framework for enforcing environmental legislation and working with the Drinking Water Inspectorate. Obviously, I will continue to hold their feet to the fire as the Minister, because we rely on their reporting back.
Rebecca Pow
Yes, of course it does, and the EA is funded. There is a framework through which it operates, but of course if we can stop the storm overflows being used so much and we can work with the farming community to reduce the pollutants that they release into the water space, all of those things will help to reduce overall pollution.
I am very grateful to the hon. Lady for introducing this debate on sewage discharges and the impact on water quality. I hope that I have conveyed to her that it is a subject that I am taking extremely seriously and working on. Measures are being put in place. I urge her to keep up her work, too, because the more of us who work on it the more success we will have.
Rebecca Pow
Of course environmental standards are crucial, as is the monitoring that goes into informing us about what is happening in the water space. We have left Europe now, as she knows, but that does not mean that we will in any way reduce our environmental standards—indeed, I believe that we can strengthen them. We can have much more bespoke systems for the whole environmental space.
I hope that the Government have demonstrated, even in the past couple of months, how much we are putting the environment at the top of the agenda. Even in this very difficult time for us all, we have committed to protecting 30% of our land space and 30% of our waters. A raft of measures and our green recovery challenge fund demonstrate that the Government are putting the environment and all that that encompasses right at the top of the agenda. I thank the hon. Lady again for raising the subject.
Question put and agreed to.
