Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, what steps his Department is taking to promote the separation of clean water from (a) sewage systems and (b) natural surface water drainage ponds in new housing developments.

The Government is strongly committed to improving the implementation of Sustainable Drainage Systems (SuDS) and we are looking at what additional steps might be taken to support this. Better delivery of SuDS may be achieved by continuing to improve the current planning policy-based approach and looking at ways of improving the approach to adoption and maintenance, rather than commencing schedule 3 to the Flood and Water Management Act 2010. A final decision on this matter will be made in the coming months.

In June this year, the Government introduced new national standards, making clear that SuDS should be designed to cope with changing climatic conditions as well as delivering wider water infrastructure benefits in the form of flood prevention and storm overflow reduction, offering reuse opportunities, reducing run off, and helping to improve water quality, amenity, and biodiversity.
