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

To ask the Secretary of State for Environment, Food and Rural Affairs, what assessment he has made of the potential merits of supporting the installation of water saving technology designed to conserve rainwater, make appropriate use of greywater and reduce flooding in (a) new build and (b) existing properties.

In our 2021 written ministerial statement on reducing demand for water we committed to developing a roadmap towards greater water efficiency in new developments and retrofits. As part of this roadmap we are exploring water saving technologies including rainwater harvesting and greywater reuse.

In August 2021 the Government announced a review of the implementation of Schedule 3 of the Flood and Water Management Act 2010. The review is looking at the benefits and impacts of implementation and the Government will publish the review and decision regarding implementation of Schedule 3 to the Flood and Water Management Act 2010 in due course.
