Environment Bill

Debate between Lord Cameron of Dillington and Lord Blencathra

Committee stage
Monday 5th July 2021 Lords Chamber

[Lord Cameron of Dillington (CB) [V]]

My Lords, we now enter the chapter in this Bill on water, which has attracted a lot of attention in both Houses and in the outside world. The first thing to say is that undoubtedly Defra and the Government have recognised the concerns across the nation about the state of our waterways and, in this chapter, have tried to put in place actions to improve the situation. So at least from my perspective, there is none of the indignation I felt when trying to sort out the set-up of the OEP.

I hope all my amendments to this chapter are as helpful as intended. I, and others, are trying to make certain that what the Government are trying to do really works for all those whose lives are touched by our aquatic environment—and that is probably most of us.

Amendment 160A is on “may” or “must”. I know the Minister, in his letter to us today, indicated that the point of the word “may” is to allow the Government to consult, but the Defra fact sheet that also came out today indicates that it has already consulted the water companies on this matter. I guess my point is that, if the idea is good and the water companies have been consulted, it must be done—and this is a good idea.

We know for a fact that some parts of England, notably the south-east, will be stretched to provide enough water for all human needs over coming decades, let alone for nature. If we are going to build 1 million new homes along the Oxford-Cambridge arc and 300,000 new homes every year, which we probably need to, if Southern Water is predicting a supply-demand deficit by 2030 equivalent to 50% of its current supply, and if we are going to get hotter summers, meaning less rain and more evaporation, we have to do some serious planning sooner rather than later, as proposed new Section 39F in Clause 77 rightly suggests we do.

I like the idea of moving water between catchments; I also like the idea of more reservoirs, probably numerous smaller reservoirs, which might be easier to plan, bearing in mind that there have been no significant reservoir constructions in England for over 40 years. I know we are coming on to abstraction later in the Bill, but this is a serious issue that needs serious long-term planning. There is no “may” about it; it quite clearly “must” be done.

The purpose of my next two amendments, Amendments 160B and 160C, is just to bring the necessity of putting the all-important wider consultation process, and the stipulation of who is to be consulted, under the “must” part of the clause as per Amendment 160A. Note that this is consultation on what the regulations should cover, not on whether they should actually be introduced because, in my view, they should all be “must”s. I beg to move.

[Lord Blencathra (Con)]

My Lords, I declare my environmental interests as in the register. I support the noble Lord, Lord Cameron of Dillington, and his Amendment 163A, which encourages sewerage under-takers to consider nature-based solutions for wastewater treatment.

We have new and emerging threats in trying to treat wastewater. We have microplastics and increasing levels of hormones and other pharmaceuticals, as well as an increasing range of chemicals flushed down toilets to clean them. These are called contaminants of emerging concern—CECs—and the traditional approach would be to use different and even stronger chemicals to neutralise them, although I am not sure how one can neutralise microplastics. This is where nature-based solutions can play a big part. We all know that nature-based solutions near and on rivers can reduce flooding, cut down on nutrients getting into rivers and the sea and improve biodiversity. They can do the same thing before treated water even gets to the rivers.

In the next group is the new clause from my noble friend the Minister on stormwater overflows, which is long overdue. We must stop ordinary rainwater from entering the sewerage system and adding millions of gallons of clean water to wastewater, making the whole lot in need of treatment. In addition, we need a campaign to educate householders not to pour gallons of poisonous cleaners down the loo. I think we are still trapped—well, some older noble Lords might remember this—in the old Harpic advert of the 1980s, with its slogan of it being essential to clean “right round the bend”. It was a great slogan that has encouraged millions of us to use unnecessarily powerful chemicals to tackle a non-existent problem of cleaning sewerage pipes and not just the toilet itself.

In addition to reducing the amount of water which becomes wastewater in need of treatment and reducing the poisons we add to it, we need sewage treatment works to adopt, where possible, alternatives to chemical treatment. The main alternative has to be reed beds, which work exceptionally well and do a perfect job. Of course, reed beds and treatment require space and they are not the solution for many urban areas but they can be a much greater solution than they are now. Amendment 163A merely states that a sewerage undertaker in its management plan must address

“the opportunities for nature based solutions”.

As I read it, there is no compulsion, no fixed targets; it merely asks them to look at the opportunities to do it. In my opinion, that does not impose an unreasonable burden on them and I urge my noble friend the Minister to accept it, or accept the concept, anyway.
