Water (Special Measures) Bill [ Lords ] (Fifth sitting)

Jerome Mayhew Excerpts

Committee stage
Thursday 16th January 2025 Public Bill Committees

[Jerome Mayhew (Broadland and Fakenham) (Con)]

I am sympathetic to quite a lot of the intention behind the new clause, but as ever, the devil is in the detail. Proposed new section 272B(2)(d)(ii)(a) contains a duty to publish the start time, end time and duration of all sewage spill events. Does the hon. Gentleman accept that there has already been a duty to publish that information for some time? All undertakers have a duty to publish information from event duration monitors within—from memory—60 minutes of an event being triggered. Will the hon. Gentleman give a bit more detail on what he has in mind for the authority to publish? Proposed new subsection (2)(c) says that the database must

“contain such data or information as the Authority thinks is necessary”.

Such a bland statement will be open to challenge and interpretation, with all sorts of committed parties deciding that their “independently collected and analysed information” should be in the database, and other people saying it should not. Is this not just a charter for judicial review of the authority?

[Tim Farron]

I will not rehash the debates we have had in Committee already, but we are talking about more than just event duration monitoring, as set out in proposed new section 27ZB(2)(d)(ii)(a); we are talking about flow and volume, and it is right to specify those things.

[Jerome Mayhew]

That may be the hon. Member’s intention, but the drafting does not say that. Part of the problem is that (ii)(a) deals the with start time, end time and duration, not flow. Does that particular sub-paragraph not duplicate the existing legal requirements for publication within 60 minutes?

[Tim Farron]

We dealt with that with other amendments; even though they are not part of the Bill, that would be covered by the suite of things we have proposed. Fundamentally, all we are asking for is that the information and the evidence that is put out there will be searchable historically. That cannot be beyond the wit and capability of the very clever IT specialists who I am sure are already working for the water companies. This is important, and it is part of what those of us in this corner of the Committee Room are trying to do, which is to take the Government at their word when it comes to the elevation—and we support that elevation—of the role of volunteers and citizen scientists, equipping them to do their job properly and not expecting them to be at their computers 24/7 without sleep.

[Charlie Maynard]

I thank the hon. Member for that intervention. I do not know when that changed. [Interruption] In 2015, was it? There we are: maybe it was changed in 2015. Perhaps all of us, or most of us, recognise that is not a good situation. Time and again—I have seen this in Witney, Ducklington, Bampton, Aston and Carterton—this is just waved through. When I quiz people from Thames Water about why they have waved it through, they say, “We have a duty to connect.” They do have a legal duty to connect, which they take seriously, but they take their duty to add capacity to match that increase much less seriously.

[Jerome Mayhew]

This is a request for information on my part. In my conversations with Anglian Water, one of its key asks relates to the imbalance in which the company has a legal duty to connect any planning application that is passed, yet it is not a statutory consultee. It is therefore not required—not able, in fact—to take part in the planning process. Until the companies are made statutory consultees, all this is irrelevant, so should not the new clause focus on their becoming statutory consultees?

While I am on my feet, I have a query about the drafting. The hon. Gentleman defined a “relevant time”, but I do not see that definition in the new clause. Is it contained somewhere in the draft legislation? If it is not, what might the effective definition be?

[Charlie Maynard]

The point about “relevant time” is fair and deserves to be clarified. I completely agree on the issue of statutory consultees and have no issue with that either—that would make much more sense, because there is a real failure in that regard.

I will go a step further—I have lived experience in this regard—and give a special shout-out to Thames Water employee Richard Aylard, who for two years dutifully showed up every six weeks with West Oxfordshire district council to hash through these issues. I learned a lot from him and am grateful to him, as well as to Jake Morley, Lidia Arciszewska, Phil Martin, Laurence King, Alaric Smith and Alistair Wray. They sat through all that, and we all learned together. It is important that everybody knows what came out of those meetings. When sewage treatment works’ capacity is calculated—they are very much under-capacity in my patch and, I am sure, in those of other hon. Members—there are four criteria. The first is the population or population equivalent, which is normally optimistically understated. The second is per capita consumption. Thames Water has a high per capita consumption when it suits the company and a low per capita consumption when it suits the company, so again that is understated.

The third is the Environment Agency multiplier, which is typically 3.0, and is discounted far too often. When there is a known record of spills, Thames Water is still allowed to discount the EA multiplier, often from 3.0 down to 2.4; that is a 20% cut, which means that the capacity can be 20% less. That is a real problem, and it is being done repeatedly on sewage treatment works that have dumped sewage left, right and centre for years.

The fourth criterion is infiltration. Some 47% of the capacity of west Oxfordshire’s big nine sewage treatment works comes from infiltration. That means that our pipes are leaking. There is not enough science on this matter. If we were to put in flow meters, we would have the information, but it seems that we Lib Dems are the only team in the room, alongside the hon. Member for Waveney Valley, that advocates flow meters. If we want to solve these problems, we have to get serious about the information.
