I thank all noble Lords for their thoughtful and helpful contributions on these important issues.
The drainage and sewerage management plans introduced by Clause 78 will deliver improvements for both customers and the environment. They will be produced at least every five years and cover a 25-year planning horizon, enabling sewerage undertakers to develop and maintain a complete picture of their networks, including their capacity and the future demands on them. This is essential for undertakers to understand risks to their networks, their customers and the environment, and to develop mitigations to address them.
Regarding Amendments 162 and 163 in the name of the noble Duke, the Duke of Wellington, Amendment 164 from the noble Lord, Lord Bradshaw, and Amendment 192 from the noble Baroness, Lady McIntosh of Pickering, the Government wholeheartedly agree that water companies must improve their drainage and sewerage systems and report on discharges. It is for this reason that Clause 78(3) sets out the specific matters that drainage and sewerage management plans must address. Plans must provide an assessment of the sewerage undertaker’s drainage and sewerage system capacity, including “current and future demands”, as well as its resilience. The sewerage undertaker must set out in the plan how it will maintain an effective system of sewerage and drainage and when any necessary actions with regard to this will be taken.
Paragraph 681 of the Bill’s Explanatory Notes makes it explicitly clear that
“environmental risks will include storm overflows and their impact on water quality.”
The relevant Ministers may also make directions specifying additional matters that must be addressed by the plan. I want to be clear that the Government will not hesitate to use this power of direction if any sewerage undertaker’s plans fall short. The Government are also clear that sewerage undertakers must be transparent. Clause 78(5) requires sewerage undertakers to review their plans annually and
“send a statement of the conclusions of its review to the Minister.”
In addition, the new government amendments to the Bill, which we discussed on Monday, will further commit English sewerage undertakers to report annually on storm overflow activity.
Finally, the plans will facilitate collaboration between sewerage undertakers, local authorities and developers to understand proposed new housing developments and possible future pressures that may be placed on an undertaker’s system. Drainage and wastewater management plans will be taken into account for the first price review and every subsequent review. My understanding is that work on the next review begins pretty much immediately after the first review is finished. I say that in response to the noble Baroness, Lady Bakewell, who I think raised that issue.
I move to Amendments 162A, 163A, 175A, 193 and 194A from the noble Lords, Lord Cameron of Dillington and Lord Berkeley, the noble Baroness, Lady McIntosh of Pickering, and my noble friend Lord Caithness. The Government are clear that we expect plans to deliver for both customers and the environment. I am pleased to inform noble Lords that the UK Government, the Welsh Government, Ofwat, the Environment Agency and Natural Resources Wales will shortly be issuing joint guidance to undertakers making it clear that we expect them to consider green infrastructure and nature-based and low-carbon solutions when mitigating risks.
As I said on Monday, our view is very much that, where a nature-based solution exists, it must be the default. In these days of tightened budgets and reduced access to resources, it is incumbent upon government to make sure that when we purchase a solution, it delivers in the broadest possible way and, almost every time, that is a nature-based solution. I hope that that reassures the noble Baroness, Lady Bakewell, who made a very passionate case for nature-based solutions. Clause 78 must therefore be as broad as possible to enable all this to continue as plans are placed on a statutory footing. Again, I reassure noble Lords that the Government will not hesitate to make directions to undertakers specifying additional matters that must be addressed by the plans if they are inadequate.
I emphasise that it is current government policy that nature-based solutions should be considered first, as I said earlier. The Government promote the use of blue-green infrastructure, such as sustainable drainage systems, grey water recycling and natural flood management. Indeed, the National Planning Policy Framework already ensures that blue-green infrastructure is provided in all new developments unless there is clear evidence that this would not be appropriate, and it should be given priority in new developments in flood risk areas.
Last year, the Government also published the Flood and Coastal Erosion Risk Management: Policy Statement, which sets out our long-term ambition to create a nation more resilient to these increasingly unpredictable risks. The statement sets out our commitment to
“double the number of government funded”
flood management projects, which includes natural flood management. Alongside this, the Government’s Storm Overflows Taskforce, set up to eliminate harm from storm overflows, is considering a number of drainage issues including blue-green infrastructure, and will be reporting in the summer.
I take this opportunity to add a response to a comment that was made by the noble Lord, Lord Cameron of Dillington, on this issue right at the
end of the debate on Monday. He suggested that I had dismissed the possibility of eliminating harm from storm overflows on the basis that it would be too expensive. That really is not at all what I said. I pointed out the estimated cost, which is anything from
“£200 billion to £500 billion”.—[Official Report, 5/7/21; col. 1137.]
We do not know exactly how much it is going to cost. It is therefore surely right that a Minister standing at the Dispatch Box should not casually accept an amendment that would lead to that scale of investment over an unknown period. However, we are committed to tackling this area and are doing the work to inform the appropriate policy steps. Like all noble Lords who have spoken on this issue, we do not regard it as acceptable that sewage is poured into our waterways and water systems.
The Government’s environmental land management schemes also have reduction of flood risk as one of the key outcomes eligible for public money. The Government have committed to delivering an integrated approach to managing water, and the actions I have outlined will support water quality, flood risk management and climate resilience goals to protect communities and the environment. They will also contribute towards the Government’s commitment to the UN’s global sustainable development goals.
Regarding Amendment 194 tabled by my noble friend Lady McIntosh of Pickering, water and sewerage undertakers and internal drainage boards maintain strong relationships and engagement with local authorities in relation to planning. This helps identify significant future developments long before formal planning consent is sought for them and enables early discussion.
Clause 78 provides for regulations as to
“the persons to be consulted”
on drainage and sewerage management plans. The meaning of “persons” is very broad and will enable the Government to set out in regulations all existing statutory consultees as well as a range of other stakeholders to be consulted. As water companies will co-operate with developers and local authorities in the preparation of their drainage and sewerage management plans, this will help mitigate the impacts of automatic connection by planning better for future housing developments. I say that in response to my noble friend Lady McIntosh, who rightly raised that issue.
Also, for my noble friend’s benefit, regarding the assurance provided by my honourable friend in the other place, Rebecca Pow, I can reconfirm and reissue that assurance here in front of this Committee. Under the Flood and Water Management Act 2010, water and sewerage companies and a number of other bodies are statutory flood-risk management authorities and therefore must co-operate with each other. To avoid any possible doubt, we are committed to preparing an amending statutory instrument to ensure that it is crystal clear.
I will respond very briefly to the noble Baroness, Lady Hayman. We refer to drainage and sewerage management plans in the Bill because that is the wording used in the Water Industry Act, which this Bill amends. I am assured that it means the same thing in real terms and there is no discrepancy.
Regarding Amendment 175 from the noble Lord, Lord Teverson, I am pleased to say that my right honourable friend the Environment Secretary last week published a Written Ministerial Statement on reducing water demand. This announced actions the Government will take in response to the 2019 consultation on measures to reduce personal water consumption. In response to the noble Lord, Lord Berkeley, this includes plans in 2022 to
“develop a roadmap towards greater water efficiency in new developments and retrofits”,
including through building regulations and using new technologies to meet these standards. I am happy to confirm that we will be considering the use of grey water recycling further as part of this work.
The lead department in relation to planning is of course not Defra but MHCLG, and I am in regular discussions with that department, as is my noble friend Lady Bloomfield. I have been asked by the Secretary of State for MHCLG to help identify things that need to be included in building regulations that will further add to protections of the environment, not just in relation to water but to a whole range of biodiversity and nature-related issues. That is an invitation that I and Rebecca Pow will greedily accept.
2.30 pm
We will also ensure that any relevant underlying legislation can, where appropriate, accommodate any potential future expansion of rainwater harvesting as well as other water reuse and storage options. I hope that the details I have set out about how the measures in this Bill and future actions will interlock with and support other areas of government policy on water management have been helpful. Sustainable management of water delivers multiple benefits to society and the environment. I thank noble Lords for their contributions and hope that I have shown that the Government have listened. I respectfully ask that the amendment be withdrawn.
