Sankey Brook Proposed Flood Risk Management Scheme

The proposed schemes on these pages are currently still in the appraisal stage meaning funding has not been secured. There is therefore no guarantee that these schemes will secure funding and progress to a completed flood scheme. For more information on how Flood Risk Management Schemes are funded and delivered, please visit our dedicated page here.

The Sankey Brook Flood Risk Management Scheme (FRMS) aims to reduce the flood risk to homes and businesses from Sankey Brook, Dallam Brook and Longford Brook in Warrington. There are more than 1,700 residential properties currently at risk of flooding during a 1 in 100 year flooding event (1% chance of occurring in any given year). The onset of flooding for some of these properties is as frequent as once every 10 to 20 years. Key areas include Sankey Bridges, Dallam, Bewsey and Callands.

The Environment Agency will be working in partnership with Warrington Borough Council, United Utilities, the Department for Education, and the North West Regional Flood and Coastal Committee.

This project is a recommendation from the Warrington Flood Risk Management Strategy (dated 2010).

Linking to this Strategy, to date the Environment Agency have delivered the River Mersey Flood Risk Scheme in Warrington which provides flood protection to over 2,000 properties and businesses along the River Mersey. For further information about this scheme can be found here:

We also completed, in December 2023 the engineering works on the Penketh and Whittle Flood Risk Management Scheme; and in Spring 2024 will be finalising the planting and landscaping works. This project has been delivered in partnership working with Warrington Borough Council and aims to reduce flood risk to 221 properties from Penketh and Whittle Brooks.
