HC Deb 27 October 1992 vol 212 cc946-51
Mr. Murphy

I beg to move amendment No. 14, in page 2, line 37, after 'use', insert 'and that sluices are operational'.

I understand that the Government accept this amendment.

Mr. Gwilym Jones

The Government have no difficulty in accepting this amendment, but the hon. Member for Torfaen (Mr. Murphy) may wish to reflect on whether it is necessary. Clearly, the sluices must be operational before the Rivers Taff and Ely are totally obstructed. The proposed method of construction requires that locks and sluices be completed and operational before work commences on in-filling the last 250 m gap between the embankment and the structures at the Penarth end of the barrage. Schedule 3. paragraph 2(1)(ii) requires that works or operations shall not be commenced until details have been approved by the National Rivers Authority. I can assure hon. Members that the NRA would insist that the sluices were operational before the rivers were finally obstructed. Nonetheless, I am happy to accept the amendment.

Amendment agreed to.

Mr. Murphy

Mr. Murphy

The House will know that one of the most significant problems that people have identified with the construction of the Cardiff bay barrage refers to groundwater levels and the possibility of flooding in other parts of our capital city. Because of the lack of time and because of the importance of this matter to the local press, I move the amendment and allow my hon. Friends to speak in whatever time is left.

Mr. Morgan

We are having to go at a speed, for obvious reasons, after the timetable motion. There is a large number of amendments to which we must refer briefly before the 9 o'clock deadline. Some of the amendments relate to the matter of dispute in Select Committee as it finished its consideration in February. The Cardiff Bay development corporation still took the view that it did not require any additional powers to be conferred on the Cardiff city council to deal with the problem of impregnation flooding as distinct from overground flooding by spillage of water from the rivers Taff and Ely into adjoining residential areas—classic flooding. It took the view that, if the Select Committee accepted the evidence that had been given by Dr. Miles and Professor Rushton that there could be another form of flooding—flooding by impregnation—one could handle that in the same way that one would deal with over-the-bank flooding.

At the very minute that the Select Committee finished, the Queen's counsel representing the Cardiff Bay Development Corporation was still maintaining that there were precedents for dealing with impregnation flooding as well. He subsequently had to accept that he was wrong and that the Cardiff city council's view that it would require additional powers was right. As a result, the Government had to climb down, as on so many other matters recently, and accept that the Bill would now have to be changed, but in another place. We would much rather do that job in this place, which is why we have included amendments to grant powers to Cardiff city council to deal with impregnation flooding.

Obviously, the fears that exist in some residential areas, particularly those west of the River Taff relate to what is known as the urban swamp thesis. That matter was substantially discussed in Committee. Nobody wants to live in an urban swamp. If we are to have one, we will have to drain the swamp to enable people to enjoy the residential amenities that they deserve. That is why we had a very strong reaction by the Select Committee, and why we want to incorporate it in the amendments. At page 62.3 of his evidence, Professor Rushton said: Thirdly, there is a serious risk that the construction of a barrage would lead to dangerously high water levels in several locations in Cardiff."

People would not say that for nothing if they have reputations such as the Professor's as world experts on how to drain areas. He is a civil engineer, and he made the point very forcibly that, in his professional view, that was going to be one of the problems. We want to see tonight, rather than by way of a promise from the Government, some sign of what the Government will do when the matter goes to another place, which in turn means that it will come back to this place next year in order to reconcile the two versions. That is why we have mentioned impregnation flooding.

We have also mentioned the question raised by the Wallis and Munro studies which have been independently validated as statistically worth looking at—namely, whether the health and amenity of people in areas with high water tables will be adversely affected. The Minister earlier tried to rubbish that and say that his independent experts—we do not know who they are, where they have studied, what they have done, or how they have studied the proposals—say that it is a load of rubbish and that there is no possibility of any adverse effect on health and amenity from the consequences of a high water table and waterlogging creating cooler conditions, mists and fogs and adverse effects on health.

Perhaps the Minister is right, perhaps he is wrong—we do not know. If he is right, it will not cost a penny to accept the amendments. If there is no effect on health and amenity, one does not have a right to compensation, because one will not be able to get a penny out of the Cardiff Bay development corporation. If the Minister accepts the amendment, we can all go home happy. The right exists, but it will not cost the Minister anything. Why is he unwilling to accept the amendment in the circumstances?

Mr. Gwilym Jones

Amendment No. 15 deals with the barrage design. The corporation has agreed with the NRA that the barrage will be constructed so that it can be drained between tides to a level of 1.25 m below ordnance datum. That provision is included in clause 2 (2). The purpose of that provision is to enable the pollution from any accidental discharge either into the bay or into the rivers upstream of the bay to be cleared rapidly once it has reached the barrage. The requirements have been included in the Bill at the NRA's request. Although the clause permits a change of design with the NRA's agreement, it is extremely unlikely that that body would seek to reduce a level of protection that it has negotiated with the development corporation.

The amendment seeks to permit the change in ability to drain the bay only for the reason of better flood protection. Logic dictates that any change in design that reduces the ability to drain the bay cannot have a beneficial effect on flood protection. Although the impact on flood protection of draining the bay between tides is very marginal, I cannot envisage a situation in which the NRA would agree to such a reduction for the purpose of improving flood protection. Equally, the NRA accepts that greater ability to drain the bay than already included in the Bill is not required. The amendment therefore is unnecessary, since the corporation has already designed the barrage so that it can be drained to the specified level between one high tide and the next.

Amendments No. 100, 30, 101, 34, 102 and 103 would add the alleviation of flooding by the raising of groundwater to the purposes for which the development corporation may operate the barrage under clauses 7 and 8. They would also require the corporation to operate the barrage under directions from the Cardiff city council and the NRA to prevent or alleviate flooding from groundwater.

The amendments are inappropriate for two reasons. First, they confuse surface flooding with raised groundwater levels. Surface flooding is the overflowing of rivers at times of high river flow by overtopping of the river banks.

Impregnation of the ground is the result of raised groundwater levels. The only way in which the powers in clauses 7 and 8, which deal with the operation of the barrage, could be exercised to alleviate groundwater rise is by alteration of the impoundment level below the level of 4 to 4.5 m above ordnance datum specified in clause 9. Neither the National Rivers Authority nor Cardiff city council has requested the powers that the amendments propose for them. Indeed, to give the National Rivers Authority responsibility for groundwater would provide it with responsibility for a subject on which it has no legal powers. The point was made clear in the NRA statement of December 1991.

The city council argued before the Select Committee that its powers to deal with flooding under the Land Drainage Act 1991 did not extend to groundwater. As I already explained this evening, the Government will table an amendment in another place to include the saturation of ground within the definition of flooding under the Land Drainage Act 1991.

We have no doubt about the importance of the matters covered by the amendments, but their purpose has already been achieved by other means. The hon. Member for Cardiff, West withdrew the amendments in Committee, and I hope that he will feel able to do so now.

Amendment negatived.

It being Nine o'clock, MR. DEPUTY SPEAKER, pursuant to Order this day, proceeded to put forthwith the Questions necessary to dispose of proceedings on amendments.
