WINEP Case Studies: Northumbrian Water

The movement of raw water and invasive non-native species (INNS): Improving biosecurity

This is a collaboration between 13 water companies who operate raw water transfers between their assets, together with the Environment Agency, Natural England and other potential stakeholders.

The scheme is an investigation addressing the movement of raw water between water company facilities and water bodies, which can accidentally spread invasive species. Options, issues and technologies will be assessed to improve biosecurity.

Phased over 5 years, it builds upon previously completed risk assessments. The investigation will explore the feasibility of novel options for reducing the risk of spreading INNS when water is transferred, assess the risk associated with this pathway and how to monitor the effectiveness of such interventions. A trial will be carried out of mitigation options and the monitoring of their effectiveness at suitable sites.

This investigation will improve the evidence base to determine the level of invasive species that are being transferred by raw water transfers rather than hypothetical assumptions and help develop a viable methodology to test raw water transfer biosecurity.

Other Examples:

There are 120 actions planned within the WINEP to investigate, monitor, or directly target invasive species which can have an impact on the wider native ecology, as well as use of water for consumption, recreation, and navigation.

Another example of an action planned within the WINEP to address invasive species includes Yorkshire water’s investigation into the eradication of a discrete population of narrow-clawed crayfish prior to their spread in the area and potential impacts on wider aquatic ecology.
