WINEP case study: Affinity Water (AMP7) Ex.1

Preventing introduction and spread of invasive species through partnership projects

The Water Industry National Environment Programme (WINEP) is a cornerstone of environmental regulation in England, setting out the actions water companies must deliver to meet statutory obligations and contribute to wider environmental goals. AMP7, which covered 1 April 2020 to 31 March 2025, represented one of the most ambitious WINEP cycles to date, with over 11,900 actions aimed at improving water quality, protecting biodiversity, and supporting sustainable water resources. The case study below provides an example of one of the completed AMP7 projects.

Affinity Water's 'INNS Out Scheme' supports partnerships projects in the Affinity Water catchment area that aim to prevent introduction and spread of invasive non-native species (INNS). Especially in protected sites such as those of Special Scientific Interest (SSSI).

The scheme has provided both financial and volunteer support to people and organisations in the catchment to carry out INNS prevention projects. Affinity Water's Biodiversity team, alongside other colleagues and contractors have volunteered at numerous events.

Since the launch in 2021, over 80% of applications to the INNS Out scheme have been successful and £350,000 funding has been awarded. Volunteer events have included floating pennywort removal and himalayan balsam days, along with projects tackling over 30 different species at 25 different water spaces.

The Environment Agency aims to build on the successes and continue to enhance relationships with local stakeholders and communities to reduce the impact of INNS in the Affinity Water catchment areas.
