The Duke of Wellington (CB)

My Lords, Amendment 51 in my name has been put in this group even though it relates to a different clause. Clause 3 deals with emergency overflows and seeks to define an emergency overflow. It also includes within Clause 3 what is in effect a let-out for the water companies, in that, where an overflow occurs as a result of an electrical power failure, that is permitted. I must admit that I find that surprising. I am grateful to the Minister, who allowed me to come and discuss this point with her and her officials a few weeks ago. However, I cannot for the life of me understand how failure to have sufficient electrical power generation capacity in a sewerage works is sufficient reason to allow an overflow to occur. I remember that, just before or during the passage of the Environment Act, there was a major overflow by Thames Water in London, and the reason given at the time was, “Oh, sorry, there’s been a power failure”. That really does not seem good enough. Nobody running a hospital would be able to plead lack of power as a reason to close down all operations under way in the hospital at that moment. It seems to me that a sewerage works is a place where there must be sufficient emergency power generation through generators in case of a power failure. This is a simple amendment; I hope the Government will take it seriously. It simply would delete, in effect, in new Section 141G(2)(a), “electrical power failure at sewage disposal works” as a reason for permitting an emergency overflow. That is my argument and I hope the Minister will take it seriously.
