It is a pleasure to see you in the Chair, Mr Paisley. I thank my hon. Friend the Member for Gower (Tonia Antoniazzi) for securing the debate and for her opening remarks.

I am really pleased to have the opportunity to speak in the debate on behalf of the 140 residents of Dulwich and West Norwood who signed the petition to ban raw sewage discharges, and the thousands of others in my constituency for whom this is an important issue. As a member of the Environmental Audit Committee, I pay tribute to our Chair, the right hon. Member for Ludlow (Philip Dunne), for his commitment and work on this issue over many months.

I recently had the opportunity to visit the River Windrush in Oxfordshire, where a group of local residents have come together as Windrush Against Sewage Pollution in order to take action on the impact on the ecology of the river of Thames Water’s frequent discharges into it. I pay tribute to them for their work, which has been instrumental in the struggle to hold water companies to account for the damage that they cause to health and the environment by discharging raw sewage into our rivers. Windrush Against Sewage Pollution has engaged in citizen science over several years by monitoring the water quality and ecological diversity of the River Windrush. Through such data gathering, the group is able to understand the impact of raw sewage discharge and has discovered that raw sewage discharges are underreported, going undetected by the Environment Agency in as many as 96.5% of cases. All the evidence points to the inadequacy of the Environment Agency’s action on sewage discharge.

On the same visit, we went to a Thames Water treatment works that discharges into the River Windrush. That revealed further issues with the water treatment and monitoring regime that I want to highlight. Specifically, in addition to the problem of frequent undetected and unsanctioned discharges of raw sewage, water companies are not required to measure or treat many substances that are harmful to the environment. Among them are microplastics, which are present both in river discharge and in sewage sludge, which is spread on the land for fertiliser, thereby potentially entering the food chain; antibiotics, at a time when there is a huge race against growing antibiotic resistance; and hormones, which have an impact on the reproduction of fish and other aquatic life.

We have a monitoring, treatment and enforcement framework for wastewater treatment and discharge that is simply not fit for purpose for the serious environmental challenges we face. At the same time, water companies are also failing to invest adequately in their clean water infrastructure. Across my constituency, where ageing water pipes are put under additional strain by hilly topography, there are serious water leaks and bursts every single week. I have been pressing Thames Water for years to invest in the pipe replacement that we need to secure a reliable water supply for local residents and stop the terrible waste of drinking-quality water that occurs whenever there is a leak.

I am pleased that in response to that pressure, the level of investment in my constituency has increased, but we are still far from a plan to replace all the pipes that need replacing. Thames Water still has a serious problem with the quality of its workmanship. Almost without fail, as soon as replacement works finish in my constituency, a new leak occurs because the workmanship is so poor. There have been two such instances in the last three weeks—it happens all the time.

We face a climate emergency and ecological crisis. Nature recovery is a vital part of our response to climate change, and river water quality is critical. Privatised water companies are not fit for the task. They already face competing priorities—the need for investment in both clean water and water treatment infrastructure—and are trying to face in those two different directions at the same time. They also have to face in a third direction: to deliver the returns for which they are under constant pressure from shareholders. That is not a responsible way to run such critical infrastructure, and it simply is not working.

We need the water industry returned to common ownership so that it can focus on delivering functioning clean water infrastructure and be part of the solution to the challenge of nature recovery. Our rivers and communities cannot wait any longer.

It is, as ever, an absolute pleasure to see you in the Chair, Mr Paisley. I thank all hon. Members who have taken part in this heated debate, and those people who signed the petition. Although I really respect the strength of feeling—the passion—in the petition, I want to say at the outset that I believe it was probably started when the social media campaign was whipped up. I am sorry, but a lot of misinformation was indeed spread, so we need to get over that and ensure that it never happens again.

I do understand the passion about this issue, which I think we all share. Quite frankly, I am personally also horrified by a lot of what we have seen. That is why I am so proud that, as an Environment Minister, I have made water quality a priority; indeed, so have this Government. As was so eloquently said by a number of Government Members, particularly my right hon. Friend the Member for Basingstoke (Mrs Miller), we now have a chain of actions that will deal with this. Many of them, of course, are triggered through the world-leading Environment Act. I was sorry, whatever the shadow Minister, the hon. Member for Plymouth, Sutton and Devonport (Luke Pollard), says—I do, as he knows, have great respect for him—that our Labour colleagues did not, in the end, vote to make that law to get water companies to reduce harm from storm sewage overflows. The tables were turned, and for that I am sorry. I think we need to get over that, too, and we all need to move on—

Will the Minister give way?

So I am not going to take an intervention on that.

I will also say that the issue is devolved. I thank the hon. Member for Gower (Tonia Antoniazzi) for introducing the debate. As she knows, it is for individual Governments to have their own powers, although Wales joins a great many of the powers in the Act.

I thank the hon. Lady for that; we are at pains to work with the devolved Administrations, because water does not have boundaries. I increasingly want to do exactly that, so I hand out an offer to do more. On misinformation, although I am not defending the quality of our rivers, it is comparable to that of rivers in densely populated areas of Europe.

The storm overflows system is an old Victorian plumbing system, which in many cases is not fit for purpose given our growing population, climate change and the frequent heavy extreme weather incidents that we are getting. Many hon. Members have made reference to the fact that the whole system needs improving.

I have been clear that storm sewage overflows, which are supposed to be for emergency use, are used far too frequently, which is absolutely unacceptable. I have said that frequently. We are the first Government to take decisive action on storm overflows through the Environment Act. I established the storm overflows taskforce to look into the issue and to inform us. I thank my hon. Friend the Member for Keighley (Robbie Moore), who did great work on the Bill Committee, for recognising that.

The petition calls for the elimination of storm overflows, which is a commendable ambition.

The Minister said at the start of her remarks that she thought the petition had probably been started in response to the social media campaign. To clarify, it was started more than six months ago and indeed, the Government published their response to it on 5 May.

I thank the hon. Lady for clarifying. As I said, I share the passion of the people who signed the petition, so I am not arguing about that.

The petition calls for the complete elimination of storm overflows. We need to look at how possible that is and what the function of overflows is in emergency situations. We need to look at the whole issue in the round. The recently published storm overflows evidence project report shed some light on that and the costs that we are looking at. The hon. Member for Plymouth, Sutton and Devonport keeps asking about that, but he can read all about it in an independent survey published on gov.uk. It highlights that the cost of complete elimination would be between £350 billion and £600 billion.

When we are looking at all those things, we also need to consider all the other things that we have to deal with in terms of water, such as phosphates, nitrates and soil in the water. Several right hon. Friends rightly referred to that and how complicated the picture is. We are dealing with it, as we need to.

Work is under way on that timeframe to reduce and potentially eliminate overflows. The hon. Member for Harrow West (Gareth Thomas) made some interesting points about consumer involvement and bringing the public along so that they understand what we are doing. Water companies consult consumers but, of course, that does not change their obligation to meet their requirements and regulations in law.

That is where the Government’s direction to Ofwat, the regulator, is important. We have just produced our draft strategic policy, in which we flagged the issue of storm overflows and reducing the harm for the first time. We also put the environment at the top of the agenda. I am sure we all share the view that that is the right thing to do.

The issue of enforcement has been raised several times. Action is taken and must be taken, but I understand the frustration about how long it can take. The Southern Water enforcement took years, but the fine was £90 million, which sent a clear message. Thames Water has also had some significant fines, but it is now spending £4.4 billion on the Thames Tideway Tunnel. That will be a game changer, rightly treating sewage that goes into the Thames. We have seen progress, although that is not to say that we do not need to go a great deal further.

We have seen some action. The shadow Minister keeps asking, “What is happening now?” There is some action. Yes, we need more, but through the taskforce we instigated a call for action that is happening right now. Importantly, water companies are spending £144 million in additional investment on storm overflows in the period 2020 to 2025, on top of the £3 billion they are already spending on the environment.
