Hampstead and Highgate Dams - Judical Review:  From 2006 to 2012 we have worked with the City of London to develop a plan to restore the hydrology and water quality of the ponds on Hampstead Heath. Since 2002 the City of London has been advised that the engineering of the dams would not able to cope with an extreme flood event and that should that flood event occur, the dams were likely to fail. In 2012, Hampstead Heath Society sought a Judical Review on the City of London's interpretation of the 1975 Reservoir Act and the level of safety required in the engineering of dams. The Judical Review rules in favour of the City of London and its engineers on the 28th November 2014. A copy of the ruling is attached for those that maybe interested. The ruling explores the history of reservoir safety in the UK and the intensions of the Government in setting up the 1975 Reservoir Act. THE HONOURABLE MRS JUSTICE LANG noted that the Government's "... main intentions are to ensure that, where a community could be endangered by the breach of a dam, the risk of any breach caused by a flood is virtually eliminated".  The role of the Reservoir All Panel Engineer is to ensure that the engineering of a dam "virtually eliminates" the risk to communities and the proposed works to the Hampstead and Highgate dams were deemed to meet this requirement by the THE HONOURABLE MRS JUSTICE LANG. Groups opposed to the works on the Dams have opposed the planning application for the scheme. The Planning permission for the scheme was approved by the Local Council in January 2015 and the groups opposed to the scheme are considering whether to appeal against the decision.
