Sewage Pollution: Whitburn — House of Commons, 2021-10-27
Topic: Environment
Rebecca Faye Clark (Pow) (Conservative, Centre-right): I thank the hon. Member for that. There has been no U-turn whatever. As I said, we have six pages of clauses in the Environment Bill committing to reducing sewage in our watercourses, all with essential steps that we have to take in order to fully tackle this whole issue. We have now announced a legal duty on water companies to take action to reduce harm from overflows. I am going to outline all the overall measures that we are dedicated to in this Government. There has been no U-turn whatever. Again, that is spurious spinning of the facts. I want to get that on the record I will talk a little about the sewer systems, to get all that clear. Many of our sewer systems are combined systems where sewage is combined with rainwater. During and after heavy and prolonged rain, the capacity of combined sewer systems can be exceeded. Storm overflows were a design feature of the Victorian sewers. They act as a release valve to discharge excess sewage in rainwater into the rivers and the sea if the capacity of the sewage system is exceeded. This protects properties from flooding and from sewage backing up in these kinds of extreme weather. Historically, they were designed only to be used in very infrequent, exceptional weather, but water companies are now relying on them far too often. Water companies have failed to adequately reduce sewage discharges. That is unacceptable, and I have said so unequivocally. That is why we are taking action, particularly through the Environment Bill I want to lay out the sources of pollution that we are dealing with in our rivers and marine spaces. The largest contributor to water pollution is agriculture—that is, 40% of pollution—and the water industry accounts for 36% of water pollution. Of that, a fifth is from the storm sewage overflows, but four fifths is from water that is already treated in treatment works and goes into the river. A lot of that contains too much phosphate, for example, which is one of the things polluting our rivers. That is just to get this into perspective. Clearly, action is necessary to tackle the issue on all fronts. That is why we are asking the water industry to do so much more on the environment. However, I want to put on the record that investment in this area since privatisation has been over £30 billion, so the water industry has actually invested a lot of money since 1990. Some £3.1 billion is being invested in storm overflows between 2020 and 2025. But to tackle the increasing pressures on our water environment, we really do need to do more. Reducing the frequency of the use of the storm sewage discharges is really important. On those grounds, I recently set up the storm overflow taskforce, which was tasked with a whole lot of assessments but also reporting back on what the cost of total elimination of the storm overflow outflows would be, as well as on a range of other combinations in reducing their use I want to take issue again with the stats. Nobody gave spurious statistics about this. The taskforce’s report is shortly to be published. I will share some stats with the hon. Member as she raised the issue and we need to get the record straight on that as well To reduce these overflows to zero, the taskforce has come back after much research to say that the cost would be between £150 billion and £300 billion. That would be done through increasing the size of the infrastructure, but there would still probably be some use of the overflows if we have massive storms. If we then wanted to completely separate our system so that we had one pipe for rainwater and one pipe for sewage, the taskforce estimate, after much research, that that would cost between £350 billion and £600 billion. The hon. Lady will be able to see that data clearly published, potentially tomorrow. We are happy to share that data with her just to get that really clear I have referred to some of the other measures that we are implementing to show we are determined as a Government to tackle the issue. We have set a new set of strategic priorities for the industry’s regulator, Ofwat. It is the first time any Government have set the direction in which water companies must take steps to significantly reduce the frequency and volume of sewage discharges from storm overflows. The regulator should ensure that funding should be approved to let the water companies do that. That is a really important point. As the Environment Secretary set out yesterday, we will now put that instruction on a firm legal footing. So no U-turns have occurred; this work was all in train. That direction will be enshrined in law I will just look in detail at the comprehensive measures we already voted for last week in the Environment Bill, which demonstrate we mean business on tackling storm sewage overflows. Together with the legal duty, the direction to Ofwat and the targets that will be set on water quality, the Bill will make a significant difference. Last week, on 20 October, the Government put forward six pages of new law on this issue, of which the hon. Member should be completely aware. Just in case she is not, I will run through what those things were.
