Sewers: Property Development

The question

To ask the Secretary of State for Environment, Food and Rural Affairs, whether his Department has made an assessment of the potential impact of implementing schedule 3 of the Flood and Water Management Act 2010 on the (a) number and (b) effectiveness of sustainable drainage systems in new developments.

Answered by Emma Hardy

The Government is strongly committed to requiring standardised Sustainable Drainage Systems (SuDS) in new developments. These should be to designs that cope with changing climatic conditions as well as delivering wider water infrastructure benefits, offer reuse opportunities, reduce run off and help to improve water quality, amenity and biodiversity. It is also important to ensure appropriate adoption and maintenance arrangements are in place.

We believe that these outcomes can be achieved through either improving the current planning led approach using powers now available or commencing Schedule 3 to the Flood and Water Management Act 2010. A final decision on the way forward will be made in the coming months.

We will review the planning system holistically and consider whether further changes are required to address SuDS when we consult on further planning reform, including national policy related to decision making, in 2025.
