 The issue was taken to UK Parliament by Jonathan Evans where he stated that an independent report by the Halcrow Group (advising for the Environment Agency) explained that draining the reservoir could create 'new risks to reservoir safety'.Evans' predecessor, Julie Morgan, had previously taken the issue of saving the reservoir site to parliament, and had garnered support from politicians such as Peter Hain (the Welsh Secretary) and Ed Miliband (later leader of the Labour Party), who visited the site during the May 2010 general election campaign, commenting on the site's tranquillity.In March 2011, WPD applied to Cardiff County Council for planning permission for a miniroundabout on Lisvane Road and listed building consent to alter the structure of the reservoir.
