To ask Her Majesty's Government what plans they have to implement the recommendations contained in the report by Sir Michael Pitt The Pitt Review: Lessons learned from the 2007 floods, published on 25 June 2008, in particular to end developers’ automatic right to connect new developments to public sewers.
The Government implemented recommendations from Sir Michael Pitt’s review through the Flood and Water Management Act 2010. The Environment, Food and Rural Affairs Committee’s report on the Post-legislative scrutiny of the Flood and Water Management Act 2010 was in its Sixth Report of Session 2016–17, published on 26 April 2017.
The Government response to the Committee’s report notes that planning practice guidance includes a hierarchy for sustainable drainage options that favours non-sewer solutions. Draining to a combined sewer should be the least favoured option in new development, to be considered when sustainable drainage options are not reasonably practicable. Removing the right to connect to an existing sewer therefore would offer no clear benefits over current arrangements and is likely to add costs and delay to the planning process for new housing.
