Water Supply in Kent

Kevin McKenna Excerpts

[Kevin McKenna (Sittingbourne and Sheppey) (Lab)]

It is a pleasure to serve under your chairship, Mr Twigg. I commend my hon. and caring Friend the Member for Ashford (Sojan Joseph) for securing this important debate, which is very pressing for everyone in Kent. As the right hon. Member for Herne Bay and Sandwich (Sir Roger Gale) has just said, this issue is causing a lot of anxiety and aggravation for residents across the county.

In my constituency, there are two main elements to that: the supply and the outfall—the sewage. In terms of supply, my constituency is in one of the driest parts of the country—drier even than other parts of Kent, which is already the driest part of the country—because we are on the north side of the north downs and in the rain shadow. That is great for growing apples and pears, and for a lot of the nature and wildlife that we have, but it keeps our marshes a little drier than they would be otherwise.

However, we have real challenges with the supply of water, even with the large investment coming into the area, particularly to the Isle of Sheppey, which is exceptionally vulnerable. It is connected to the mainland of Great Britain by only a single water main that goes under the bridge. I had the pleasure of going underneath the Swale to see it, and it is surprisingly narrow. The entire island—nearly 40,000 people—is supplied by that very narrow pipe. Other infrastructure on the island is old, weak and creaking, and the cast iron water mains need replacing. I am grateful that the extra investment will mean that the 11 km east-west water main across the island will be replaced.

The fundamental problem, though, is that we have not been building reservoirs across most of the country, to ensure that we can store water in the wetter months of the year. Sittingbourne is an industrial town with huge water users: we have the largest paper mill in the entirety of the United Kingdom—the second biggest in Europe—which uses massive amounts of water, as do other key industries in my constituency’s towns. They are competing with residents—my constituents—for drinking water. Ironically, the water level in Sittingbourne is very high. Since we lost the other water mill, the River Bourne, which runs underneath the town, and the river at Periwinkle are both running high. We have water in the area that is coming off the north downs, but we cannot necessarily access it for industrial use. There is a bit of abstraction, but not enough. We cannot access water for industries that could really benefit the area, such as hydrogen plants and other things that might come online.

There are options for desalination. We are coastal and have lots of marsh areas, so I would appreciate hearing what the options for Kent are from the Minister. Other parts of the world that are even drier manage better than we do, so there is a fundamental question about how resilient we are in Kent. I would also like to hear from the Minister whether we have a clear plan for securing that sort of resilience across the supply by the end of the decade. What does that look like? My local council, Swale borough council, is extremely concerned by this. It has written to Southern Water and South East Water about the supply problems we have been facing and it wants to understand what the plans are for the future.

As my hon. and caring Friend the Member for Ashford said, we want to understand why the communication has been so poor. It is poor partly because we have a hodgepodge of different organisations—multiple water companies, a drainage board and, to some extent, the Environment Agency as well, which is involved in land drainage. Who people need to go to is often confusing, and when crises are happening, it is hard to get through to the right people; it is not joined up well enough with local government. Recently, as the crisis was happening in places such as Whitstable and Herne Bay, we got a lot of emergency supply come into the area, particularly the Isle of Sheppey. Bottled water stations were set up—they thankfully did not need to be used—and water tankers were moved on, but even while that was happening, it was still hard for local councillors and me to find out exactly what was happening and where. I got a lot of agitated calls from residents and councillors saying, “Do you know what’s happening? How likely are we to lose water supply?” That needs to be tightened up.

In terms of the drainage off the land, the sewage that is going into our waterways is a real concern, as the right hon. Member for Herne Bay and Sandwich said. I am grateful that Sheerness beach recently got its blue flag status renewed—please come to Sheerness for your summer holidays. Lots of local residents have been looking at the water. In Milton Creek in Sittingbourne, Raybel Charters, a group that restored the barge there and are in the water a lot, found that it is dirtier than the River Seine. Open water swimmers have been doing inspections at Queenborough and found bacteria there. National treasure and local legend Danny Dyer, who has been filming on the Isle of Sheppey, has also been investigating, and has found shocking amounts of E. coli and coliforms in the water—he does not want to damage the tourist reputation, given his caravan park.

This is a real risk, and I want to understand what we can do about it. In particular, what are we going to do about securing future supply, especially through reservoirs and desalination plants? What is the plan, Minister?
