Contribution
My Lords, I again thank noble Lords for the discussion on this group, for their amendments and for the thoughtful consideration that we have had since Committee on these issues regarding the environmental duties of water companies and the regulators.
Amendment 26 tabled by the noble Baroness, Lady McIntosh of Pickering, and Amendment 55 by the noble Lord, Lord Gascoigne, would require water companies to consider further opportunities to use nature-based solutions. I thank noble Lords for meeting me to discuss these amendments and nature-based solutions more broadly.
One thing the Government are clear about on these amendments is that water companies need to be encouraged to increase their use of nature-based solutions. In line with that, I am very pleased to see that Ofwat has proposed an allowance of over £2 billion for investment in nature-based solutions in the draft determinations at price review 2024. Alongside this, Ofwat has been clear, publicly, that it remains open to companies to identify where additional nature-based solutions can be delivered. We very much support this approach.
The noble Baroness, Lady McIntosh, and the noble Lord, Lord Roborough, mentioned the catchment approach. Again, that is something we are very supportive of. If we are to make a real difference in our water quality, and our approaches to our waterways, we need a whole-catchment approach.
Ofwat’s £200 million innovation fund aims to grow the water sector’s capacity to innovate. Since 2020, the fund has awarded funding to 93 collaborative projects where water companies work with different sectors to solve the water sector’s biggest challenges. The main- streaming nature-based solutions to deliver greater value project is one example that is working to overcome barriers to the adoption of nature-based solutions.
What I am trying to get across is that the nature-based solutions the Government are supporting are not just about what is in the Bill; it goes much broader than that. That is important, because we need to look at this approach right across the board. I hope that helps to reassure noble Lords and answer some of their questions.
The regulators have, for example, recently approved several new and innovative nature-based solutions. One example is the use of sustainable drainage systems in Mansfield to manage flood risk. That is a £76 million scheme and includes over 20,000 sustainable additions to the built environment in the area, including rain gardens, planters and permeable paving, creating the equivalent of 23 Olympic-size swimming pools of storage and protecting 90,000 people from flood risk. Again, this is about much more than just what is in the Bill. There is further funding proposed for nature-based solutions alongside this—for example, reed beds and wetlands—and the Government are also supporting water companies trialling nature-based solutions for groundwater-induced storm overflows. There is a lot of work going on in this area.
Having said that, we recognise the strong support in this House for the Government to do more to ensure greater use of nature-based solutions across drainage and sewerage systems specifically. I am therefore pleased to table Amendments 42, 61 and 64, which require sewerage undertakers in England and Wales to address how nature-based solutions have, or will, contribute to the resilience and development of their network within their drainage and sewerage management plans. I thank noble Lords who have expressed their support for these amendments today.
Drainage and sewerage management plans are the key planning mechanism for the entirety of the sewerage undertakers’ wastewater network. This new requirement will ensure that water companies consider the use of nature-based solutions at the very start of the investment planning process. In this way, they embed solutions into delivery.
We intend to commence this new requirement very quickly—two months after Royal Assent—and it will apply also in respect of the next round of drainage and sewerage management plans, which will be published ahead of the 2029 water price review. Sewerage undertakers will need to demonstrate that they have addressed the use of nature-based solutions in their draft, and final, drainage and sewage management plans and will be held to account if they fail to do so, because there is no point in bringing forward amendments if they are not going to be delivered as swiftly and as effectively as possible.
The noble Baroness, Lady Willis, asked whether the review would look at things such as adaptation and further environmental matters around reservoirs. Absolutely: the review has a very broad scope in these areas. I remind the House that in our manifesto we pledged to build new reservoirs, because we know how critical they are.
I hope that noble Lords agree that these government amendments will support the future exploration, development and delivery of nature-based solutions by adding this requirement into existing planning frameworks.
I turn to Amendment 44, in the name of the noble Baroness, Lady Boycott. I thank the noble Baroness, Lady Willis, for introducing it on her behalf. It looks to improve public access to real time and operational water company data. I will explain why the Government do not support the amendment; I had a discussion with the noble Baroness, Lady Boycott, about this. I know that the noble Baroness has questioned this, but we believe the amendment would duplicate existing requirements for transparency from water companies.
