The site of the proposed Whittle Brook outfall PLANS to protect hundreds of homes in Penketh from flooding have been submitted. The Environment Agency has teamed up with Warrington Borough Council for the major scheme around Whittle Brook and Penketh Brook. The scheme will protect 225 homes from the risk of very significant flooding. The works involve: n Construction of a new culvert to improve conveyance under the railway line and canal and reduce the risk of flooding on the Penketh Brook. n Construction of a tidal outfall that will act to minimise tidal ingress and silt accumulation from the River Mersey.
