Water (Special Measures) Bill [HL]

Debate between Duke of Wellington and Baroness Browning

Committee stage
Wednesday 30th October 2024 Lords Chamber

[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.

[Baroness Browning (Con)]

My Lords, I am very pleased for the first time to be able to contribute to Committee on the Bill. I will speak to the two amendments in my name in this group, Amendments 54 and 88. The Minister will already be aware of my enthusiasm for the use of grey water and its importance in new-build domestic construction. I support my noble friend Lady Pickering in what she has just said on this group.

The Committee has already drawn attention to increasing problems of safe disposal of sewage from buildings and the challenge going forward to adequate supplies of domestic drinking water. The fact that the existing system cannot cope with either does not augur well for the Government’s planned housebuilding target, which will include mandatory planning targets set out in the National Planning Policy Framework.

The Minister will know from Second Reading that I support her endeavours in the Bill, but the two amendments in this group tabled in my name seek to mitigate what could quickly become a standoff between the Department for Environment, Food and Rural Affairs and the Ministry for Housing, Communities and Local Government. I urge the Minister to take some action through these two amendments to prevent this, if nothing else.

I am very grateful for the assistance and legal advice given to me on these two amendments by the lawyers at WildFish, a charity involved in the protection of all wild fish in watercourses.

Some developers argue that, because of the legal obligations on sewerage undertakers to treat wastewater, the question of sewer and sewage treatment capacity is not a material consideration in planning. There is therefore a reluctance among planning authorities to impose conditions to protect the environment from sewage pollution, partly because of the case of Barratt Homes v Dŵr Cymru 2009, where the Supreme Court confirmed that Section 106 of the Water Industry Act 1991 provided a right for householders to connect to the sewer network and that only in narrow circumstances could the water company refuse such a connection.
