Degraded Chalk Stream Environments

Jim Shannon Excerpts

Monday 22nd July 2019 Commons Chamber

[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.

[Jim Shannon (Strangford) (DUP)]

The hon. Gentleman and I share many loves of the countryside—particularly a love of country sports, but also a love of the environment. Does he agree that there is a delicate balance to be struck to ensure that companies can continue to operate as they attempt to find alternative sources of water rather than chalk streams? What more does he feel can be done as a matter of urgency to protect these environmental treasures, because treasures is what they are?

[Mr Walker]

My hon. Friend is very perspicacious in his observations. I shall come to the matter later in my speech. He is absolutely right to raise that point and I hope that both the Minister and I will be able to address it, as I know other colleagues share his concerns.

The degradation of our chalk streams is one the two greatest environmental scandals of the late 20th century and the start of the 21st. Of course, the other great environmental scandal is the destruction of the marine environment off the west coast of Scotland through salmon farming—an industry that has laid waste to numerous sea lochs off the west coast of Scotland and has destroyed the native fish runs in many of the rivers that feed those sea lochs.

It is important that I put the situation in context. As I said a moment ago, we have 85% of the world’s chalk streams and most of them are highly degraded. I find it extraordinary, given our own poor environmental record, that colleagues in this House lecture Indonesia and Brazil so freely on their responsibility to the rain forests. Of course, those two countries have a huge responsibility to the rain forests, but if we cannot save the chalk streams that are literally in our own backyard, what are we doing lecturing other countries on their environmental responsibilities? Saving the world does not start with the rest of the world. Saving the world starts right here, right now, doing our bit locally with our chalk streams—think locally, act globally.

As my hon. Friend the Member for Strangford (Jim Shannon) has just pointed out, our chalk streams are literally being abstracted to death. Parts of the streams that I named at the start of my speech do not flow. In fact, a few of them barely flow at all from their source to where they join a bigger river. That is our record and it is one that none of us should take any pride in—and it is getting worse. We have had three dry years in a row. There is this myth that we live in a wet country. Certainly, parts of our country are wet but the east and the south-east are actually dry, and they are getting drier. The aquifers are not being replenished by rainfall and they are getting more abstracted, so even less water is going into our rivers.

Let me give an example from the constituency of my right hon. Friend the Member for Chesham and Amersham. In the last 10 years alone, there have been five dry events in the Upper Chess—the most stunning river, which I have the great privilege of visiting once a year as a guest of Paul Jennings and my right hon. Friend.

[Richard Benyon]

My right hon. Friend is right. We look forward with interest to what the Glover review will deliver, because it is an opportunity to look at our most precious landscapes and to see whether we are protecting them in the right way. We have an enormous number of designatory tools at our disposal, but they do not seem to stop the problems happening or result in our Environment Agency and other organisations cracking down on wrongdoing as much as they should. This is an opportunity to stand up for what we believe in on the natural environment and say, “Here is something really special, and we are going to get it right.”

[Jim Shannon]

The hon. Gentleman, I and many others in the Chamber agree on and appreciate the wonderful work of the National Farmers Union and the Northern Irish Ulster Farmers Union on habitat, climate change, their commitment to carbon zero and many things. Should we not have on record in this debate the good work of the NFU and farmers who are committed to changes to make things better and preserve the environment for the future, which he and I believe in?

[Richard Benyon]

I entirely agree with my hon. Friend. Perhaps I can conclude by entirely endorsing what the farming unions of these islands have agreed, and Minette Batters’ very brave and clear statement about moving to net zero considerably before the rest of the country and making sure that agriculture fulfils its responsibilities. Part of that is about looking at catchments and saying, “How can we lock up more carbon?” The clear, easy way of doing that is to have a more broken-up mosaic of land use, which includes grass as part of the rotations. With encouragement for minimum tillage, not only can we start to see more carbon being locked up, but our rivers will be protected from many of the things that are causing problems at the moment.

--- Later in debate ---

[Dr Coffey]

I entirely agree, and I hope that that will happen. I think that the term of the current chair of Ofwat, who is a doughty defender of the consumer, is due for a short extension until 2020. I also genuinely believe that any future holder of the great office of Secretary of State—if that person is not our excellent right hon. Friend the Member for Surrey Heath (Michael Gove), who has done so much for the environment and, indeed, so much in challenging water companies—will take that point into account.

[Jim Shannon]

No one has mentioned one issue so far tonight, but it is important for it to be on the record in Hansard. I refer to the issue of water leakages. If there is a demand for more water—which clearly there is—water companies need to address the issue. Will the Minister make that a priority, so that water is not wasted as it clearly is being wasted now, and we can use that precious resource much better?

[Dr Coffey]

The hon. Gentleman is absolutely right. For several years there has been an economic calculation about the cost of repairing the causes of leakages rather than doing something else to keep water flowing. I will not say that the price of repairs is irrelevant, but it is not the only factor under consideration. Water users struggle. My right hon. Friend the Member for Chesham and Amersham (Dame Cheryl Gillan) spoke extensively about the water consumption of residents, and the need for us to consume less. If the water companies are allowed not to take the issue quite as seriously as they have been, why should the end user make a difference? I think that the situation is changing, but we need to recognise that the economics do not always add up.

As the hon. Gentleman will know, this matter is devolved. Our 25-year environment plan for England, which concerns reserved matters, sets out our commitment to protect our water environment and how we will do that, to ensure that there is enough water for the environment as well as for homes and businesses.

Our abstraction reform plan, launched in 2017, explains how we will ensure that abstractors can access the water that they need, and that there is enough water in our rivers, and groundwater, to maintain habitats and water quality. That includes reducing the damaging abstraction of water from rivers and groundwater, so that by 2021 the proportion of water bodies with enough water to support environmental standards will increase from 82% to 90% for surface water bodies, and from 72% to 77% for groundwater bodies. Earlier this year we published our abstraction reform progress report to Parliament, which shows that the Environment Agency is on track to meet those targets.

The Environment Agency has already reviewed thousands of abstraction licences, and has changed many of the most damaging. Seventy-one abstraction licences on 15 chalk streams across England have now been changed. Those changes will return 16 million cubic metres of water per year to the chalk streams, and will remove the risk of another 8 million cubic metres per year being taken. This is equivalent to the average annual domestic water use of approximately 200,000 people, the approximate population of Oxford.

Developing a stronger catchment focus is a key aspect of abstraction reform. The Environment Agency is now testing innovative solutions to protect the environment and improve access to water in priority catchments. The Cam and Ely Ouse and the East Suffolk priority catchments both contain rivers that are fed by chalk groundwater. In these priority catchments, there are now stakeholder groups, which are made up of a wide variety of abstractors with an Environment Agency co-ordinator, who are working together to develop and trial new solutions to address sustainability issues. I look forward to the Environment Agency launching more of these water resource catchments later this year.

The River Bulbourne in Hertfordshire is impacted by the Canal and River Trust operations, including groundwater abstractions. The Environment Agency is presently negotiating delivery of recommended solutions with the trust. Affinity Water has also completed an investigation for the River Bulbourne and as a result will implement river restoration projects in the catchment by 2025, subject to its business plan being approved by Ofwat, and I see no reason for Ofwat to reject it. The Environment Agency’s chalk stream partnership “Bringing Back the Bulbourne” has been an award-winning success story.

Turning to the River Kennet in the constituency of my right hon. Friend the Member for Newbury (Richard Benyon), the Environment Agency, working with Thames Water, has changed abstraction licences that impact the Kennet, Wye and Hughenden stream. This includes reducing Thames Water’s licence at Axford to restrict groundwater abstraction when flows are low, revoking its Ogbourne licence, and investing in a £30 million pipeline that prevents up to 10 million litres of groundwater from being abstracted when river levels are low.

Turning to parts of north London and an issue not directly in the constituency of the hon. Member for Dagenham and Rainham but close to the heart of Feargal Sharkey, the River Lee below Ware weir lock splits between the old River Lee and the Lee navigation. The loop was the original course of the River Lee and is the site of two fisheries clubs. Flows in the loop are influenced by the volumes abstracted upstream from the Lee by Thames Water and by navigation activities. The Environment Agency seeks to manage flows on the Lee between Thames Water, the Canal and River Trust and the Amwell Magna loop. Thames Water operates under a voluntary flow trigger to reduce its abstraction volumes. This assists with downstream flows but its abstraction is still a significant volume of the available flow. Thames Water has invested in habitat enhancement improvements in the loop, working with the fisheries and the Environment Agency.

Several contributors to the debate talked about the impact of dry weather on chalk streams. Some of our chalk streams are showing flow impacts that could be attributed to the prolonged dry weather we have experienced over the last couple of years. Impacts are visible in chalk streams in Cambridgeshire, Bedfordshire, Hertfordshire, north London, Lincolnshire and Northampton, but I have to admit that the national picture is variable.

The impacts we are seeing in chalk streams include changes to fish movement, a decline in the numbers of invertebrates and an increase in algae. The Environment Agency’s current actions include leading and co-ordinating the National Drought Group, which brings together a wide range of stakeholders responsible for water and for those who need the water. This partnership includes water companies, the Government and non-governmental organisations, including the National Farmers Union, environmental groups and business groups. The Environment Agency also collates and monitors evidence of impacts of dry weather on chalk streams and actions undertaken to protect the streams.

If required, the Environment Agency will implement abstraction restrictions to protect the environment. For example, as we have heard, the Environment Agency is likely to implement restrictions in a number of places, including the River Stour catchment in Essex, which is a chalk stream. That will affect 16 abstraction licences, and there will be a reduction of 25% to their weekly abstraction limit. The Environment Agency is discussing these matters with individual abstraction licence holders in other parts of the country, particularly Hertfordshire, Berkshire and Herefordshire.

My right hon. Friend the Member for Chesham and Amersham referred to the designation of sites. The Government have designated 11 high priority chalk rivers as sites of special scientific interest to protect them from the pressures they are under and to begin work to restore them. Each of those 11 designated chalk rivers that has been assessed to be in an unfavourable condition has a river restoration plan. For the record, those rivers are the Kennet, the Nar, the Test, the Frome, the Hull headwaters, the Lambourn, the Itchen, the Wensum, the Bere streams, the Moors rivers system and the Avon system. By implementing these action plans, we have enhanced more than 40 miles of priority chalk river habitat through 60 projects since 2011.

Chalk rivers are protected from harmful effluent discharges by a rigorous permitting process. When an operator seeks to discharge effluent, they must first get a licence from the Environment Agency. In consultation with Natural England, civil society and the public, the agency will then grant the permit to discharge into a priority chalk stream only if the environmental risk is low. I am conscious of the example that was used earlier, and I will draw it to the attention of the Environment Agency so that it can investigate further the concerns about discharges.

Natural England has been delivering catchment-sensitive farming, offering a combination of grants and advice to help to reduce pollution from farms within priority catchments, including chalk streams, across the country. There is clear evidence that this advice has led to improvements in water quality and a reduction in serious water pollution incidents, and ecological communities have responded positively to the reductions in sediment pressure. However, it is important to stress that all water companies also have a significant role to play in protecting the environment. A large proportion of companies look after the chalk aquifer, which is the major aquifer of southern and eastern England. These companies include Thames, Affinity, Southern and Anglian. Apparently, South East is also included, as is Yorkshire, for some reason. This just goes to show how far the power of Yorkshire stretches, as my hon. Friend the Member for Thirsk and Malton will know.

There are good examples of partnership work in action. The Environment Agency’s work with Affinity Water to reduce abstractions at 11 pumping stations across seven chalk streams means that 70 million litres of water a day will be kept in the environment by 2025, and they have reduced abstraction from the River Mimram and the River Beane by over 40%. In the north London and Hertfordshire area alone, the Environment Agency is working to improve more than 150 miles of chalk streams by 2025. The agency also hopes to remove or bypass 50 weirs or other structures to improve fish passage and habitats in the north London area.
