Degraded Chalk Stream Environments

Oliver Heald Excerpts

Monday 22nd July 2019 Commons Chamber

[Mr Charles Walker (Broxbourne) (Con)]

Thank you, Mr Deputy Speaker, for calling me for my Adjournment debate this evening. I am delighted that I did not try your patience with a spurious point of order, as that really would have been naughty. If I had tried your patience with a spurious point of order, it would have been on an environmental matter, and I would have just wanted to know how I could bring to the attention of this House the fact that, on Friday afternoon, the Secretary of State refused a planning application by Veolia to build a massive incinerator in my constituency. I was delighted with the refusal, and I now hope, as do all my constituents, that Veolia will give up its plans to put the incinerator in my constituency, give up trying to put one in Hertfordshire and disappear. If I had made a spurious and bogus point of order, that would have been it.

[Sir Oliver Heald (North East Hertfordshire) (Con)]

rose—

[Mr Walker]

I will give way on that point, but I would like to get to the substantive part of my speech.

[Sir Oliver Heald]

Does my hon. Friend agree that mine was not a spurious point of order? I have seven chalk streams and I want to make a speech.

[Mr Walker]

Of course, and there was nothing spurious about my delight at Veolia failing to get its application through—it was just that I wanted to bring it to the attention of a wider audience.

[Mr Walker]

I thank my right hon. Friend for alerting the House to that very important point. HS2 does pose a risk to chalk stream and riverine environments. No doubt if time allows, my right hon. Friend will bring her concerns to the attention of the House.

[Sir Oliver Heald]

I had miscounted; I have eight chalk streams in my constituency.

[Mr Walker]

My right hon. and learned Friend is such an honest and decent man. He could have misled the House that there were seven chalk streams in his area, but he has corrected the record without being summoned back—in fact there are eight.

Let us now get to the serious part of this debate, because this is a very serious matter that causes a great many colleagues on both sides of the House a huge amount of concern. The Colne; the Beane; the Mimram; the Gade; the Ver; the Chess; the Misbourne; the Wye; the Rib; the Hamble; the Bulbourne; the Quin; the Hogsmill; and the Wandle. The list could go on, but these are all chalk stream rivers that are degraded or dying around my constituency in Hertfordshire and the constituency of my right hon. Friend the Member for Chesham and Amersham (Dame Cheryl Gillan) in Buckinghamshire. This country has over 85% of the world’s chalk streams, and these streams are a unique habitat.

[Sir Oliver Heald (North East Hertfordshire) (Con)]

I pay tribute to my hon. Friend the Member for Broxbourne (Mr Walker) for his remarkable and important efforts in this area.

In my constituency, we have eight chalk streams: the Upper Rhee, the Rib, the Ash, the Quin, the Beane, the Mimram, the Lea—near Bayford, where I think my hon. Friend fishes—and the Ivel. There has been some progress with the Beane and the Mimram following the WWF campaign “Rivers on the Edge”, of which Martin Salter was a strong supporter and about which we had debates in this House. There has been a 90% reduction in abstraction at Whitehall pumping station near Watton-at-Stone, and the Fulling Mill pumping station at Welwyn Garden City was completely decommissioned; that represented some success.

As my hon. Friend said, however, the condition of the northern part of the rivers is very dry. The Upper Rhee is dry, and there is a lot of concern about the Rib in the Standon area and north of Standon. The situation is similar with the Ash and the Quin. The Beane at Walkern, north of Watton-at-Stone, is short of water. There is a campaign in the constituency of my hon. Friend the Member for Hitchin and Harpenden (Bim Afolami) about the Mimram. The Lea is low, and the Ivel springs in Baldock are so dry that people regularly write to me to express their concern.

It is worth thinking about what the unique chalk stream environment is like. My constituency has small hills, between which are the chalk streams, and they create a unique environment with unique flora and fauna. Nestling in the environment provided by these ecosystems are flowers such as saxifrage, as well as small English crustaceans and the water vole. Tewinbury nature reserve is a very good place to measure the activity of flies and little creatures, and that is a remarkable thing to do. I pay tribute to the Herts and Middlesex Wildlife Trust, which does so much to support that.

[Mr Charles Walker]

I am sorry to cut my right hon. and learned Friend off as he is paying tribute to the Herts and Middlesex Wildlife Trust, but I want to pay tribute to it as well. Jeremy Paxman recently wrote that we no longer have to clean our windscreens, because there are now no insects splattered on them. There are so few insects because our rivers—and, in our part of our world, our chalk streams—have been so degraded that insects can no longer live there. Without insects, we have no fish and no kingfishers; the whole ecosystem and food chain begin to collapse. My right hon. and learned Friend is entirely right to raise that concern.

[Sir Oliver Heald]

I am grateful to my hon. Friend for that intervention. People such as Jeremy Paxman, Feargal Sharkey—he used to be a pop star but now spends his time campaigning on this issue—Charles Rangeley-Wilson, whom my hon. Friend will know, and Martin Salter, on the angling side, are dedicating their lives to trying to make people realise that this environment is as precious as the Brazilian rainforest. We have a major part of a unique environment. The water that comes up—or should do—from the aquifer is so pure, and that is a wonderful thing.

As my hon. Friend said, the problem is a mixture of abstraction; climate change, which means that in the next 25 years we will have 20% less water than we do now; and growth in housing, which means that we are trying to do more with less water. Some of the predictions that house builders and developers make in planning applications—they say that they will be able to get people to use no more than 100 or 120 litres of water a day—are just not in the real world. In my constituency, the average is about 175 litres a day. The first thing that people do in a water-efficient house is to put in a power shower, spoiling the good work of the designers. My hon. Friend is right to say that those predictions do not add up.

Soil erosion is a big issue, on which I have campaigned with WWF; it recently ran a campaign about the subject. As has been said, one of the effects of not having strong rivers is that they end up with soil in them, particularly if farming techniques are not respectful of the surrounding environment. In an area such as ours with hills that have chalk and soil on top, it makes a lot of sense to go for no-till farming, so that the soil is not blown off the tops of hills and into rivers. There is a lot that can be done.

I pay tribute to the societies in my constituency—including the Friends of the Mimram, the River Beane Restoration Association and the new organisation for the River Rib—which are trying hard to highlight the plight of the rivers. Despite the campaigns, the work that has been done and the reports in this House going back some years, we have made only a little progress against a background of deterioration. It is a question of one step forward and two steps back. I am grateful to my hon. Friend for raising this issue and giving us a chance to highlight the importance of this environment and ecoculture. Much more needs to be done.

On the Abingdon reservoir, I came into this House in 1992, and Thames Water was lobbying us then about building the Abingdon reservoir. Here we are 27 years later, and it has still not been built; it is still a few years away. We need to get on and do this. The background is against us, and action is needed.

--- Later in debate ---

[Dame Cheryl Gillan]

I am afraid my hon. Friend is right. I came into the House at the same time as my right hon. and learned Friend the Member for North East Hertfordshire (Sir Oliver Heald), in 1992. That reservoir is not overdue, but long overdue and should have been built many years ago.

May I also pay tribute to the authors of “Chalk Streams in Crisis”? Four of the organisations that contributed are closely associated with my constituency. The Chilterns chalk streams project—a fantastic project started in 1997, prompted by the low flows in the 1990s—was expanded in 2000 to include all the rivers. It is led by the Chilterns Conservation Board, with the River Chess Association and the Berkshire, Buckinghamshire and Oxfordshire wildlife trusts. All these organisations work constantly and tirelessly to try to protect our environment.

[Sir Oliver Heald]

In my constituency, there are people who can remember swimming in the River Beane north of Watton-at-Stone when they were very young; now it is completely dry. Does my right hon. Friend have constituents with such recollections about the Chess?

[Dame Cheryl Gillan]

Yes, very much so. Both the Chess and the Misbourne, at times in the past, flowed really well and invited people in during the hot weather, such as we are going to experience this week, in safety. Safety is very important, because although there is now the amazing rough swimming movement, it is important to remember that rough swimming must be carried out in safety. People need to think about how they are getting into the water and how they are getting out. I fear there will be plenty of people diving into the water later this week, as the temperatures soar.

--- Later in debate ---

[Richard Benyon]

I have heard similar stories, and I do not know the circumstances of this. I wrote to the company before this debate asking for it to give its side of the argument, but I did not hear back. I am not necessarily criticising the company, as I approached it only at the end of last week.

My point is this: in our management of these rare systems, we need not just to be getting the sort of thing I was just discussing right, but to be looking at agriculture. My right hon. and learned Friend the Member for North East Hertfordshire was so correct in what he said about that. Min-till—minimum tillage—agricultural systems are vital, not least because of the worms that are allowed to prosper in the soil, which affects the permeability of that soil crust so that water goes through to the aquifer, rather than running off and taking with it a lot of the topsoil. We have a wonderful, rare and special opportunity that we can now deliver through the Agriculture Bill and the environment Bill. We are talking about changes that can make sure we are incentivising farmers and working with them right across a catchment to deliver extraordinary benefits.

[Sir Oliver Heald]

I wonder whether my right hon. Friend would wish to comment on the state of the River Kennet, which is a precious chalk stream close to him. Where does he think the Kennet is going—is it improving? Some attempts were made to improve its condition. Secondly, when he was preparing the water White Paper, I think he was hoping that it would be possible for water companies to move water more easily from one area to another. Has he any take on how that has been going?

[Richard Benyon]

One of the most enjoyable things I did in government was writing the water White Paper, and I refer my right hon. and learned Friend to page 35—I think that was the one. It showed a scene of good farming on one side of a river and bad farming on another, so that figuratively laid out before us was what we needed to see more of and what we had to stop happening. I bored my civil servants with that and I bore most of my family, with my wife referring to the River Pang as my mid-life crisis, but the River Kennet is in such trouble. A few years ago, someone spilled about an egg cup-worth of Chlorpyrifos into the system somewhere and it effectively killed several miles of life. That shows us just how extraordinarily vulnerable these ecosystems are.

We can debate great matters of state in this place, and we often do, but rivers are about people’s sense of place. As has been said, we can hold our heads high internationally if we are getting it right on rivers and we cannot if we are getting it wrong. What is shaming is that, while 85% of the chalk streams in the world are in the UK, we are getting it wrong. Wonderful things are done by organisations such as Action for the River Kennet and many of the other organisations that hon. Members in all parts of the House have talked about, but I believe the recommendations at the end of the river fly census are really worth reading.

In the context of the water framework directive, which we are transposing, correctly and with more ambition than exists in that directive as it stands, we should have a special designation for chalk streams. We should also look at the impact of phosphorus spikes and recognise that after we leave the European Union the world is our oyster and we do not have to be stuck by the same rules that govern rivers in southern France and northern Spain. This is our ecosystem, and we have to get it right.

--- Later in debate ---

[Sir Oliver Heald]

When I spoke earlier, I made the point that builders and developers have suggested that it is possible for new homes to achieve water use of perhaps 120 litres per person per day. At the moment, in my constituency and others, the figure is about 175 litres. What does the Minister make of that? Does she think that such a reduction is realistic?

[Dr Coffey]

It is entirely realistic. Indeed, we want to go further and get the figure down to 110 litres. We believe that that is entirely possible, and I will address that further in my contribution, especially as the hon. Member for Warwick and Leamington (Matt Western) referred to it as well.

Work has also been done by water companies to improve the water quality of chalk streams, which my hon. Friend the Member for Broxbourne also identified as an issue. More than £3.4 billion has been invested between 2010 and 2015 to support the achievement of the water framework directive environmental objectives. I shall repeat that figure: £3.4 billion has been invested by the water companies. This has contributed to substantial reductions in phosphate pollution, to which chalk streams are particularly sensitive, and additional investment is proposed to secure further improvements. Water companies are also engaged in research to overcome technical limitations on phosphorus reduction. Additionally, 650 sewage treatment works across England, serving 24 million people, have phosphate removal in place, and many of them are on chalk streams.

The Government expect to see a multi-sector approach to managing water resources and want water companies to continue to engage in the catchment that they serve. We want them to take the lead on developing local catchment solutions to address the needs of all water users in their region. We are already seeing how this can work. I am particularly proud of Anglian Water, as Water Resources East is taking an innovative cross-sector approach and making important links to improve water abstraction management.

As my hon. Friend said, a large proportion of the water that is abstracted is for public supplies. Reducing the pressure on such supplies will also help to protect the environment. To do this, we need a twin-track approach of reducing demand for water, including driving down leakages, while increasing supply. That is why we recently launched a consultation, to which I hope my right hon. and hon. Friends will contribute, to understand by how much we can reduce personal water use by 2050 and the measures we need to implement to get there, including tightening building regulations, the labelling of water-using products and metering. This autumn, we plan to lay our national policy statement for water resources infrastructure, which will streamline the planning process for nationally significant water resource infrastructure projects, helping to increase water supplies.

I hope my hon. Friend will appreciate that Thames Water and Affinity Water are still developing their water resources management plans. They recently referred their statement of responses to their consultations to DEFRA, which the Department and the Environment Agency are assessing. That process is ongoing, and that assessment includes the proposed reservoir near Abingdon. The evidence from the National Infrastructure Commission is clear that new water infrastructure is required alongside a reduction in leakage, and I welcome the proposals from Thames Water, Affinity Water and others to develop regional strategic solutions for the south-east.

We want to see water companies taking more of a regional approach to water resource planning. They will need to make an assessment of the needs of different water users, including the owners of new homes, and the needs of the environment. That will be informed by the Environment Agency’s national framework, which is due to be published at the end of this year and will illustrate the regional and national challenge of water availability, as well as the needs of different water-using sectors.

I am pleased to say that we have also consulted on legislative improvements to ensure that water companies’ plans are informed by effective collaboration, taking into account the plans of regional groups. We also recently consulted on a number of additional legislative measures regarding abstraction. Ofwat, the Environment Agency, and the Drinking Water Inspectorate all recognise the importance of a regional approach, which is why they set up the water Regulators Alliance for Progressing Infrastructure Development—water RAPID—team to ensure a smooth regulatory path for strategic water transfers and joint infrastructure projects.

My right hon. and learned Friend the Member for North East Hertfordshire (Sir Oliver Heald) mentioned several streams in his constituency, and he is a champion on this matter. Anyone who looks at his website will see the long list of actions that he has taken, and he is right to praise the Herts and Middlesex Wildlife Trust for its important work. I have already referred to my hon. Friend the Member for North West Hampshire and the fact that I grew up in Whitchurch, so I know about the importance of the River Test. My right hon. Friend the Member for Chesham and Amersham referred to the important Ox-Cam issue, and my hon. Friend the Member for North West Hampshire is the Minister for that project and is aware of the importance not only of environmental issue, but of the water needs of households in that area.

My hon. Friend the Member for Broxbourne started to talk about windscreens, insects and so on, and the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services report recognises the biodiversity challenge that we face. The main problem is with habitats and the change in land use. Rivers also face challenges, and he is right to stress that. As my right hon. Friend the Member for Newbury (Richard Benyon) pointed out, 80% of species under threat of extinction are invertebrates, which is why we must cherish habitats such as chalk streams.

I should also point out to my right hon. and learned Friend the Member for North East Hertfordshire that the aerodynamics of modern cars also contribute to our seeing fewer dead insects on our windscreens, but we are also driving somewhat slower because we are complying with speed limits when compared with what we might have got away with in the past—not “we”; I should not attribute that comment to any person in this House. He also talked about soil erosion and no-till farming, and I completely agree with him and the others who made this point. They should be champions for no-till farming, but they also need to be champions for glyphosate, as the people who advocate no-till farming rely on glyphosate. Indeed, its existence is under threat from 2022.

--- Later in debate ---

[Sir Oliver Heald]

Will my hon. Friend give way?

[Dr Coffey]

I am afraid that I will not give way on that point, because I am still trying to answer the points raised by other hon. Members. We may have time at the end of this debate, but I feel there is another time for another debate on the glory of glyphosate—I am sure that I will be slandered on social media tonight for having said those words. My right hon. and learned Friend also mentioned how long it has taken to get a new Thames reservoir, and I genuinely hope we will see the plan come forward soon.

The hon. Member for Warwick and Leamington referred to his childhood roots, and in this House it is always important to recognise that, although we represent very special parts of the country, we sometimes have our roots elsewhere, which I think makes us better politicians. I appreciate that he has stayed here to talk about the impacts. He also mentioned grey water resources and how they might help water consumption. Indeed, there is a theory that the consumer is not keen on grey water, and we might need to do more work to promote the use of grey water resources in the water challenge of new homes, which I am sure he will recognise are important to his constituency, as they are to other parts of the country.

My right hon. Friend the Member for Chesham and Amersham also talked about water consumption, and I hope she will participate in the consultation. Importantly, she mentioned the challenges faced by the River Chess and the River Misbourne. It is astonishing to hear that the average consumption is 173 litres, which we need to change. I am sure she will be an active champion on that matter, as we already know she is an active champion on behalf of her constituents when it comes to High Speed 2. She referred to a number of different issues, but I am conscious that her work on the possible impacts on Ox-Cam will not have been lost on the Housing Minister, who was present for the majority of the debate—he had the wisdom perhaps to leave for my contribution.

My hon. Friend the Member for Chelmsford (Vicky Ford) told us of her intention to go up the River Chelmer on a canoe, and I hope she returns with a paddle. My right hon. Friend the Member for Newbury, who I am delighted to say is leading a review on highly protected marine areas, does not forget the rivers and streams in his own constituency. Indeed, he referred to a number of them, including the River Lambourn.

On the number of years of drought—just make it rain—it is perhaps of some comfort to the Prime Minister that, in her three years in office, she has never had to worry about a flood or a drought. Who knows how long that luck can last?

My right hon. Friend the Member for Newbury highlighted that 80% of species are invertebrates, which get ignored in our debate on the environment, and I am glad he is here today. He also talked about chemicals going into the water. That is important, and in the development of our chemical strategy over the next year, the Government will take account of how we get the balance right on chemicals, which produce much magic for our everyday lives, but we need to be very conscious of the impact they can have. Of course, he also referred to the River Kennet and to water transfer.

A number of issues have been raised about how we need to preserve these habitats, and I fully agree. The habitats in our country are so special. They are quite a small part of our British Isles, but they are so important to the world, which is why this Government will continue, in the 25-year plan, to make sure we pass on an environment that is in a better state than this generation inherited. We will do that domestically and internationally.

I thank the House. I know this has been a long debate, but one of the special things about this Chamber is that something that might seem quite parochial has huge global significance, and I am delighted to have shared this debate with so many right hon. and hon. Members tonight.
