I beg to move,
That this House has considered sewage discharges.
It is a pleasure to serve under your chairmanship, Ms Elliott. I thank all colleagues who are here to debate this important issue. I also thank the public and the e-petitioners for driving us to seek this change. I welcome the Minister to her place, and I pay tribute to my right hon. Friend the Member for Ludlow (Philip Dunne), the Chairman of the Environmental Audit Committee, for everything he has done on this matter. Many hon. Members wish to speak, so I will try to limit interventions. I recognise that there is a Minister here—my right hon. Friend the Member for Hereford and South Herefordshire (Jesse Norman)—who cannot make a speech, and I hope some of these words will apply to him.
Let me illustrate why I sought this debate. As of 16 September, on nine out of the 16 days of the month Bexhill’s beach had been issued with a pollution risk warning and signs warning against bathing because of the risk of sewage discharge. On 18 August, a fault at a pumping station at Galley Hill caused a discharge of waste water, and sewage was pumped into the Bexhill coastline. It lasted for two and a half hours, starting at 2.59 pm, and bathers were not warned about what was occurring until early evening. In the settlement of Heathfield, residents at the bottom of the hill are up to their knees in discharge when heavy rain comes. That has led to rat infestations, illness for children and pets and contamination of homes and gardens.
Our sewerage system is not fit for purpose, and yet we keep building homes in these areas and making the situation worse. Much of our nation is covered by combined sewerage systems comprising hundreds of thousands of miles of sewers. When those systems cannot cope with the volume, rather than back up into properties, they discharge into our seas, our rivers and our waterways from approximately 15,000 combined sewer overflows. The practice is disgusting. Last year, there were more than 370,000 monitored spill events. Every discharge impacts our environment and our marine life, and our ability to enjoy it and make a living from it. This can no longer be tolerated.
Successive Governments have failed to tackle the issue, going back to the 19th century when much of the combined sewerage system was installed, although I welcome the Government’s latest steps to tackle the problem. Our job is to find solutions. With that in mind, I have four issues that I wish to touch on, and I will ask the Minister a number of questions.
The first issue is the storm overflow discharge reduction plan. I welcome the concept, but we could be more ambitious with the deadlines to eradicate storm overflows. The plan relies on data being correctly and fully recorded. Many citizen scientists, for whom we should all be very grateful, believe that the discharges are not fully recorded. I therefore ask the Minister the following questions. Given concerns about under-reporting, is she confident that the discharge data is accurate?
The event and duration of overflow discharges is monitored, but not the volume and impact. The Environmental Audit Committee recommended the installation of volume monitors on overflows. Will the new Minister explain why the Department rejected that recommendation?
Given that the 2035 and 2050 targets have been criticised for lacking sufficient ambition and urgency, will the Minister consider allowing Ofwat to permit sewage companies to deliver their improvement plans earlier and to higher standards? Southern Water, in the area I represent, aims to meet the storm overflow targets, but it would hit 80% by 2030, rather than 75% by 2035, which is the Government’s target.
The second issue is bathing water testing and quality. To use an example local to me, Bexhill’s bathing water quality is rated sufficient. There was a concern recently that it would drop to poor. The town comprises 40,000 people, and that number swells during tourist season. To assess water quality, testing occurs weekly between May and September. It is tested at different times of the day, but always in the same place in the sea. I am told that the water is tested in the busiest part of the beach, but our beach has no focal point and surely a wider area of bathing water should be tested. We are adjacent to excellent bathing water at St Leonards, so swimmers cross from excellent to sufficient in one stroke.
Every day—I am sure it is the same for other colleagues—the Environment Agency sends me pollution risk warnings. However, for many days, Bexhill has been the only beach where signs advising against bathing should be displayed. When I asked what made Bexhill unique, given that it rains across the Sussex coast, I was told that there was something particular about Bexhill and heavy rainfall. In Bexhill’s case, the testing place is adjacent to an outlet coming from a stream, which is the responsibility of the Environment Agency. In three years in which the agency has tested sub-optimal bathing water, Southern Water’s own testing in the immediate vicinity has come up clear on the same day.
Many suspect that heavy rainwater is coming from the highways into the stream and then entering the sea. That may or may not be the cause of the low bathing water quality. However, the fact that we do not know why our bathing water is only just sufficient tells us that we do not know enough about what is going on and therefore we do not know how to clean things up.
Does the Minister believe that it would be more optimal to test water quality on different parts of the beach and on a continuous basis? Given that the bathing water testing regime is some 30 years old, does she believe that the Environment Agency’s testing takes into account the latest pollutants, such as plastics, and gives an adequate reading of our bathing waters? Will the storm overflow discharge reduction plan prioritise busy bathing areas, such as Bexhill, which have bathing quality status below excellent or good?
The third issue is the impact from roads and house building. I will refer to the experience of residents in Heathfield, who have been blighted by sewage and flooding, and they still are when heavy rain comes. This is not just about the sewage companies, but about highways agencies ensuring that their drains can take heavy rainfall rather than it ending up in the combined sewer and causing a discharge or backfill. Despite this, Heathfield has more house building on top of the ridge below which these other roads sit.
On house building and roads, does the Minister believe that it is right to put the onus mainly on water companies to deliver fixes in the storm overflow discharge reduction plan, when many of these assets and the responsibility for them rest with the highways authorities? Has she considered giving the highway authorities a statutory duty to act and to maintain these assets after action has been taken, along with the funds that are to be generated for the plan? Alternatively, would she consider a prohibition on surface water from the highways entering the sewerage system? Either would reduce the chances of the combined sewer becoming overwhelmed in inclement weather. Next, will the Government commit to implement the plan for sustainable drainage systems—or SuDS, as it is known—thereby removing the automatic right to connect to the public sewer system, in order to prevent new developments from adding more surface water to the combined sewerage network?
Highways authorities can refuse to allow connection to their water courses. Will they be required to provide this access in order to avoid a situation in which developers connect to the combined sewers? Will the planning provisions in the forthcoming Levelling-up and Regeneration Bill enable further action to ensure that development takes place only where it will not put further pressure on the combined sewerage system, or will it provide local planning authorities with a justification for saying that further house building cannot take place without the establishment of separate drainage systems? Will the new planning rules allow for sewage companies to be statutory consultees on new planning applications rather than on just the local plan? My right hon. Friend the Member for Ludlow has a fine amendment in mind for that, and I would fully support it.
The final piece is the role of all of us—the role of the public. With more understanding of the combined sewer system and a demand that we end discharges into our waters, the public stand ready to play their part. However, many householders just do not know whether they are putting the heavy rainwater from their gutters into the sewerage system. If they did, many of them would take action to halt the flow and thereby halt the number of discharges when the system is overwhelmed. It might be cheaper to provide water butts to homes for free than to cope with an overwhelmed drainage system.
Will the Minister consider a requirement for householders to be informed if they have a combined sewerage pipe from their homes? Will she consider further financial incentives for householders to ensure that their rainwater goes into a water butt or tank, to help to reduce volume and to help when water is scarce in drier times?
I am so pleased that we are having this debate. I will end my remarks there because so many people wish to speak, and I am grateful to the Minister for the response that she will give.
As everyone can see, this is a highly subscribed debate. If everyone gets to speak—I want to try to get everybody in—they will have a minute and a half. I will have that limit informally for the first couple of speakers, but I will quickly introduce it formally if people do not stick to it.
Thank you, Ms Elliott, for chairing us so efficiently. I thank the Minister for the responses she has given. I thank the other two Front-Bench speakers, the hon. Members for Leeds North West (Alex Sobel) and for Kilmarnock and Loudoun (Alan Brown), and all the other colleagues who have come forward with their ideas. With so many ideas having been put forward, would it be possible for the Minister’s Department to collate those in its response, so that we get a full response?
The hon. Member for Leeds North West asked whether we in East Sussex are satisfied. We are never satisfied in East Sussex! That is what keeps us here. My neighbours —my hon. Friends the Members for Hastings and Rye (Sally-Ann Hart), for Eastbourne (Caroline Ansell) and for Lewes (Maria Caulfield)—and I are in a car. It is the East Sussex car and we will continue to drive it.
I will say this to the hon. Member for Leeds North West: I could give him £56 billion-worth of reasons why I am happier, because this Government are the first to do something about it. No other Governments have. We should all encourage the Government for that.
The hon. Member for Leeds North West is right that I did vote with him and my right hon. Friend the Member for Ludlow (Philip Dunne). However, we were not voting to end discharging, as has been put out on social media—not at all. It was just discharge at certain levels. Nobody who voted the other way was doing anything but voting for improvements for the first time. It pains me to see some of the abuse that goes on. We are not campaigners here. We can work effectively together for all of our constituents’ sake to make a better environment. All I would hope is for us to stick with the facts and the ideas and be nicer to each other and to our waterways.
Question put and agreed to.
Resolved,
That this House has considered sewage discharges.
