Thames Tunnel

Baroness Gardner of Parkes Excerpts

Monday 18th July 2011 Lords Chamber

[Baroness Gardner of Parkes]

My Lords, is the Minister aware that the London Group had the benefit of a presentation on this project? It said that one of the important features was to allow drainage in London, as the water level is now rising so high that it is becoming a problem, particularly with the development of more basements and sub-basements.

[Lord Henley]

My Lords, my noble friend is absolutely correct in talking about problems of drainage. We have seen, since Bazalgette built the original sewers some 150 years ago, a vast expansion of London, a vast increase in the number of people here, and a vast increase in the number of impermeable surfaces which allow water to drain off far quicker than it did in the past, creating serious environmental problems. As part of this process we need to look at all of those factors and all appropriate solutions.
