Flood gates to be installed on River Irwell to help protect homes from '1-in-100 year' catastrophe

Plans have been lodged to install flood gates on the River Irwell to provide protection to thousands of homes and businesses in Radcliffe. The Hardy’s Gate Bridge flood gates in Radcliffe would be designed to reduce the risk of a repeat of the extreme floods of Boxing Day in 2015 if approved.

That day was classed as an ‘extreme flood event’, measured to be the worst on record on that stretch of the River Irwell. The harm associated with the rainfall from Storm Eva was considered to be extensive.

More than 700 homes and businesses were affected as well as critical infrastructure such as substations, which caused further electrical failures to around 1,500 properties. The nearby waste water treatment plant was also overwhelmed by the rain and also polluted the flood-water.

Flood defence schemes have already been completed or approved at Close Park and Dumers Lane for the downstream element and another phase for flood defences have been built at Tork Street, Redvales Business Park, Bury Point, Keswick Drive, Warth Business Park and Lower Hings.

"The two flood gates will extend across Dumers Lane to secure the bridge if an extreme flood event were to occur. Each flood gate has been devised to achieve minimum level of 69.85m based on the likelihood of 1-in-100-year event, with an
