National Policy Statement (Waste Water)

Debate between Baroness McIntosh of Pickering and Mark Field

Monday 19th March 2012 Commons Chamber

[Mark Field (Cities of London and Westminster) (Con)]

I am one of 144 Members of Parliament in the Thames Water area directly affected by the issue of the Thames tunnel, and I hope that both the Minister and the hon. Member for Luton South (Gavin Shuker) will forgive me if I restrict my comments to the area that is close to my heart.

It is good to have consensus at times in politics and to be able to discuss issues in a measured way. One of the difficulties with the Thames tunnel is that there will be one hell of an outcry from many Thames Water customers in the years to come when they recognise the sheer cost implied by what is being put into place through this national policy statement for waste water, as it affects not only the London area, but the Thames Water area. Those living in the centre of London will see the tunnel being constructed, as I am sure it will be in the years to come, and will recognise that that does not come entirely cost free. I suspect that Thames Water customers in the Oxfordshires and Gloucestershires of this world will put a lot more pressure on. It is, therefore, all the more important that I use this opportunity to put certain concerns about this policy statement on the record, although I do not wish to break away too far from elements of the happy consensus that we have seen tonight.

I think we all acknowledge that if the Thames tunnel goes ahead, as I confidently predict it will, it will be a nationally significant infrastructure project. It is therefore sensible to make it one in the formal sense, both in relation to the Planning Act and, as the framework suggests is needed with such projects, with the sort of national policy statement we are debating tonight. I agree with other Members that although this debate has been relatively short, this opportunity to debate such a crucial issue is welcome. The Select Committee on Environment, Food and Rural Affairs certainly thought so when it examined this draft national policy statement last year, as we gathered from my hon. Friend the Member for Thirsk and Malton (Miss McIntosh) earlier.

The Committee also signalled some concerns about the way that the document appeared to pre-empt elements of the planning process. The waste water NPS is the key document against which the planning application for the Thames tunnel will be judged. For that reason, the Committee said that it should be “a purely generic document” to prevent the justification for the Thames tunnel project from being removed from scrutiny. It also warned that although reference to specific schemes could be put in an annex to the national policy statement,

“it should be made clear that it does not constitute information to which decision makers must have regard when considering project applications.”

I fear that the Government have rejected that element of the advice. Instead, the NPS makes it clear, on page 21, that the tunnel is the “only option” and that what would be left to the Planning Inspectorate would merely be the “specific design and route”. In its response to the Select Committee report, DEFRA said the Government want to provide a “degree of certainty” to Thames Water. I do not think there is any doubt that they have been able to achieve that result.

Let us be quite clear about what the national policy statement means in practice. It means there will be no independent analysis of the very case for a tunnel. The document we are debating removes the case for the tunnel from the planning process. I think the Minister will argue that that is reasonable because the arguments have already been heard in detail—perhaps privately in his office and the offices of his predecessors—that the evidence is overwhelming and that the final NPS makes an unarguable case. If that were true, he would have a point, but the NPS is far from entirely convincing, not least because there are a number of things that one would never learn just from reading the document. In my brief contribution tonight I shall list the ones that seem the most significant, and I join the Select Committee in asking whether there really is no need for an independent assessment.

First, the tunnel will not collect 39 million tonnes of sewage. Like Thames Water, the NPS mentions 39 million cubic metres of discharge into the Thames each year. It then states that the Thames tunnel is the preferred way to address this issue. The casual reader of the document will assume that the tunnel collects 39 million tonnes of discharge, but that figure will be more than halved without the tunnel being built. The construction of the Lee tunnel and the upgrades to the sewage treatment works will prevent 21 million tonnes from entering the tidal Thames, and improvements to Mogden sewage treatment works will tackle several million more upstream.

Rather than celebrating the huge strides already being made to clean up the Thames—I am not entirely complacent about that; there should be huge strides and we should always be looking to improve the quality of water in the Thames—the NPS makes only oblique references and never entirely quantifies them in the way that I have tried to do tonight. It is worth repeating that the amount of sewage entering the Thames will fall dramatically without the Thames tunnel project. Only 18 million tonnes of discharge will be addressed by the tunnel, by no means all of which would be stopped as there would still be three large discharge events in an average year.

Unlike the publicity we have seen from Thames Water the NPS does at least describe the discharges as a mixture of “untreated sewage and rain water”, but it does not explain that the rain water accounts for more than 95% of the total. That somewhat disingenuous use of statistics has understandably misled countless members of the public and even Members of this House. In last week’s debate on the Water Industry (Financial Assistance) Bill, my hon. Friend the Member for Hendon (Mr Offord) talked about tackling the

“39 million tonnes of effluent”—[Official Report, 14 March 2012; Vol. 542, c. 306.]

but the reality is that there are just 18 million tonnes of discharge, of which not even 1 million tonnes are effluent. Any discharge of sewage is regrettable but we should deal in facts.

[Miss McIntosh]

When the Committee put questions on the national policy statement to the Department, we asked particularly about the potential impact of SUDS and other rainfall harvesting. If, as my hon. Friend says, we are talking about mostly rainfall, that impact would be quite substantial.

[Mark Field]

I accept that there would be an impact, but the use of the word “effluent” in relation to the 39 million cubic metres gives the public and many Members of this House a somewhat misleading impression of the sheer urgency of the need to undertake the project at this time.

It has been asserted that the river has been getting better and will continue to do so, and there is no doubt about that, but a feature of debates on the Water Industry (Financial Assistance) Bill last week and less recently was the number of hon. Members who suggested that the Thames had been getting worse, and will continue to get worse without the tunnel. The hon. Members for Hammersmith (Mr Slaughter) and for Islington North (Jeremy Corbyn) made that statement in part. That claim is not supported by the facts, as regards the immediate future; it is also probably not entirely true as regards the past and present.

I note that the Environment Agency’s website no longer hosts a press release that it issued only 17 months ago, but at that time, it went so far as to describe the Thames as

“the beauty queen of the planet’s waterways.”

That perhaps goes a little too far, even for those who have no desire whatever for a Thames tunnel-type project, but what prompted the comment was real enough: the sustained and continuing improvement of the Thames, which saw it win the international Theiss river prize for outstanding achievement in river management and restoration.
