My Lords, apart from the Government, I have the bulk of the other amendments in this group so I thought I would go through them now. I thank the noble Baroness, Lady Willis; she is very knowledgeable and it is interesting to hear what she has to say. She brings an extra dimension to our debates on this issue, and I hope the Minister will agree with that.
Part 7 provides an opportunity to address nutrient pollution, particularly from development. There is a duty on water companies to upgrade their sewage disposal works; that is welcome, but some of our amendments are to do with the wording, because we are a bit concerned that the wording about how water companies are to deliver the required upgrades is unnecessarily prescriptive. For example, Amendments 391 and 393 look at how the Government have come to the wording of the exemptions. Amendment 391 is to new Section 96D in Clause 153, which says:
“A plant is exempt … if … it has a capacity of less than a population equivalent of 2000”,
while further down it says,
“the plant has a capacity of less than a population equivalent of 250”.
The amendments probe where those figures have come from and why they are there.
My Amendment 400 probes whether broken sewage monitoring stations are contributing to sewage discharge. We are aware that Ofwat has recently announced that water and sewerage companies will face increased penalties from 2025 for using faulty or broken equipment to measure pollution from storm overflow pipes. Obviously we welcome that announcement, but the Government and the regulators need to enforce existing legislation. My amendment would place a duty on the Secretary of State to monitor the situation so we would ensure that what is legislated for actually happens. The narrow focus on sewage disposal works locations also means that the upgrades will be delivered onsite, usually through the traditional engineering methodology, which the noble Baroness, Lady Willis, talked about—using concrete, steel and chemicals has a high carbon cost.
My Amendment 401 probes the implementation of the environmental action plan. It asks the Minister for an explanation of how that is related to Part 7 and how it all ties together.
My Amendment 402 probes the potential for rebuilding sewage works with new concrete and steel rather than creating woodlands, reed beds and wetlands. The noble Baroness went into a lot of detailed explanation about why we need both options. A prescriptive site-specific approach closes down that environmentally beneficial alternative for upgrades. Habitat restoration can be done from wetlands and riparian woodlands and you can enhance farmland through hedges—the Minister knows all this. It would be good if that were also included as an option.
We know there have been pioneering partnerships between water companies and nature organisations, including locally where I am in Cumbria, and they have demonstrated how effective habitat restoration can reduce nutrient pollution levels and achieve nutrient neutrality. Again, why not use those pioneering partnerships to drive forward best practice? Other countries have done so, such as Belgium, so there is proper evidence and information as to why that is a good way forward.
I shall be brief because we still have quite a bit to get through. I finish by reiterating our strong support for everything that the noble Baroness, Lady Willis, has said and her amendment, and I urge the Minister to consider accepting it. We also support the amendment tabled by the noble Lord, Lord Stunell.
