News: Waverley drainage plans outlined at Catcliffe meeting

Specially designed drainage solutions for the proposed Waverley community development have been outlined at a public consultation meeting in Catcliffe. Experts from Jacobs, who have developed the surface water drainage system for the site, were on hand to answer questions from flood-concerned residents at the consultation event at Catcliffe Memorial Hall on Friday 16 May. The plans include a gravity fed Sustainable Urban Drainage system utilising restored contours to discharge surface water into large reservoirs, which would contain and then release water into the nearby River Rother at a restricted rate. This ensures river levels are not raised excessively downstream and meet strict requirements of the Environment Agency and Rotherham Metropolitan Borough Council. The reservoirs can accommodate the volume of water for a 100 year design storm plus 30 per cent for the potential impacts of climate change. A management company for the site will maintain the surface water drainage system. Swales are also being included in the proposals in conformity with sustainable urban drainage principles and will connect to drainage channels. Approximately 35 per cent of the whole site will be impermeable.
