I am absolutely not saying, “You’ve never had it so good,” but I am drawing attention to the actual data, so that we can make a balanced judgment. I will come to some of the disadvantages of the last 30 years later on in my speech, so I hope I will give a balanced judgment.
We have dealt with the rivers and serious sewage incidents—[Interruption.] Hon. Members should wait and not be hasty. Sewage discharges from storm overflows have been, without doubt, the greatest area of failure for decades, in both public and private ownership. Why? It is because the problem was hidden for decades. It was not reported, and it was not measured. Back in 2010, the Labour Government monitored only 7% of storm overflows. As a result, we had no idea how frequently storm overflows were being activated, or for how long. Worse, Labour changed the law in 2008—I think one Labour Member present was in Parliament at that time—to allow the water companies to self-monitor their environmental performance.
The Liberal Democrats do not come out of this very well, either. [Interruption.] We can all agree on that. During the coalition, there was a Liberal Democrat Water Minister from 2013 to 2015. What action did they take when they held the levers of power? Absolutely none.
It was the Conservatives who forced transparency on the water industry by requiring 100% of storm overflow data to be monitored and then published within 15 minutes. That exposed the problem, and we then took action through the £56 billion storm overflows discharge reduction plan to fix the problem over 25 years. We all want to go faster, but it is about the balance between costs, the industry’s ability to react, and the time a responsible Government have to take these decisions.
We also had a plan to improve the water quality of chalk streams, which is an issue close to your heart, Madam Deputy Speaker. I believe you have the Test in your constituency, and I can beat that with the Stiffkey, the Wensum, the Bure and a couple of others.
Despite the unacceptable storm overflows, the question we need to ask is whether river water quality has got better or worse under privatisation. The difficulty is the lack of comparative data, because as we have monitored more, we have more data points identifying more discharges that were previously unrecorded. One of the best datasets to look at is invertebrate biodiversity, on which there has been a comprehensive study by the UK Centre for Ecology & Hydrology, analysing 223,000 samples taken between 1989 and 2018. It looks for biodiversity gain or loss, especially in species that are particularly sensitive to clean water—the mayfly and the caddisfly. You will be pleased to know, Madam Deputy Speaker, that invertebrate biodiversity has tripled in our rivers over the last 30 years, during the period of privatisation.
I am not defending the water companies’ lack of inquisitiveness about the number of storm overflow discharges. This terrible problem has to be addressed, and it was being addressed by the last Conservative Government, but it prompts the question: has our water got better or worse, in aggregate, over the last 30 years? The data suggests that it has got considerably better.
I will talk about the pros and cons of privatisation in terms of funding. In my view, there are definite cons to the private ownership model we have had over the past 30 years. I concede that some water companies have exploited weak regulation to take advantage of their monopolistic position. True competition cannot exist because we have monopoly providers. The role of competition is meant to be provided by regulation and, too often, the regulation has been found wanting, particularly on the financial engineering of the leverage that water companies undertook in the noughties, peaking in about 2015.
Again, I accept that that is a problem that should have been prevented, but all the major parties are guilty and played their part. It started under Labour and continued under the coalition—I am afraid that both the Liberal Democrats and the Conservatives have their fingerprints on this—before stopping in about 2015, when Ofwat belatedly tightened up its provision. Members will have noticed that the latest return on capital allowed by Ofwat is, from memory, 3.4%, which I submit is a reasonable return on capital and one that individuals might get from a high-interest account.
I hope that I have given a balanced assessment of the good and bad of privatisation over the past 30 years. We need to do that, because it is the basis on which we address the next question about the Bill: what is the right mechanism of ownership? In my view, privatisation has, on balance, been a success, because it has managed to lever in investment to improve our water quality overall, to reduce leakage and outages in the way that I have described, and to provide us with the safest water in the world.
