Flood Risk Management

Lead Local Flood Authority (LLFA)

The Flood and Water Management Act (FWMA) 2010 introduces a range of new powers, duties and responsibilities and makes Knowsley Council a Lead Local Flood Authority (LLFA). The Flood and Water Management Act 2010 sets out the requirement for LLFAs to manage 'local' flood risk within their area. 'Local' flood risk refers to the flood risk from surface water, groundwater and/or from ordinary watercourses. (An ordinary watercourse is any river, stream or channel which is not identified on the Environment Agency Flood Map as a Main River). Flooding from Main Rivers, the sea and large reservoirs is managed by the Environment Agency.

What are we doing / our responsibilities?

Who we are working with

  • The Environment Agency - Manage the risk of flooding from main rivers, reservoirs, estuaries and the sea.
  • United Utilities - Operate and maintain the condition of sewerage systems including foul, surface water and combined systems.
  • The Merseyside Partnership (Liverpool CC, Sefton MBC and Wirral MBC)
  • Knowsley MBC’s Highway Authority
  • Other neighbouring authorities
  • Local Flood Action Groups
  • Riparian Owners - Maintaining the river bed and banks within their section of the watercourse. A riparian owner is anyone who has a watercourse within or adjacent to any boundary of their property.

Are you Flood Ready?

Flooding can have devastating impacts and it’s important that you are prepared.

The North West Regional Flooding Resource website will help you understand more about flooding and provide you with practical advice about what to do before, during and after a flood.

Be prepared and keep up to date with the latest flood warnings from the Environment Agency and Met Office.

Knowsley MBC also has guidance on preparing for emergencies.

The Flood Hub

The Flood Hub has been designed to be a one stop shop for flood information and resources to support householders, businesses and communities across the North West in becoming more flood resilient. We have pulled together multiple sources of guidance to produce a hub of information that gives an overview of flood resilience and it’s many related topics. By signposting a variety of other useful sources, you will easily be able to find all the information you need either within our content or by visiting one of the linked websites.
