Biodiversity Action Plan

Why is biodiversity important?

A healthy environment is critical to our business and with 85 per cent of water we supply coming from sources beneath the North Downs and the remainder from the River Eden, we rely heavily on the environment to be healthy and abundant.

We impact the environment every day with the emissions we create and energy we use through the water treatment process. To protect and enhance the environment both now and in the future, our Biodiversity Action Plan within our business strategy sets out to:

  • Minimise the impact that we and our customers have on it
  • Actively improve areas of benefit to our customers

How will we deliver this?

For the successful delivery of our Biodiversity Action Plan (the Plan) the following key areas have been identified across the business for us to focus on:

  • Company land management
    • Continue keeping our Company land rich in biodiversity while meeting all legal requirements for supplying drinking water
  • Minimising the impact of Company activity on the environment
    • Prevent potential loss of biodiversity and mitigate risks to the environment as a result of Company operations and reinstate the environment where loss has occurred due to our operations
  • Partnership working
    • Extend our work with these groups to both enhance but also protect existing biodiversity
  • Engagement, education and awareness raising
    • Raise awareness and report our activities to reach the largest number of people possible while making sure the information and work we have delivered is used to inform catchment decisions

Our actions:

  • We’ve begun phase one of the Plan and are carrying out habitat surveys on Company land
  • Following hedgerow training for our outside maintenance staff, we enhanced the hedgerows on company land in early 2018
  • We’ve begun surveying for (and controlling) invasive non-native species on our sites to avoid any spread and treating those identified appropriately
  • We have initiated the process of achieving the wildlife trusts ‘Biodiversity Benchmark’ to achieve continual biodiversity enhancement and protection on three of our sites by 2025
  • We have identified conservation and environmental volunteer days which we promote to our employees to get involved in

Case studies

We installed eel screens at our Goat bridge site in Hackbridge to support the recovery of eel populations in 2017.



Barn Owl boxes have been installed on land we lease to Kent Wildlife Trust near Bough Beech, Edenbridge. This increases the available areas for barn owls to nest and to help reverse the loss of nesting sites.



Chalk grasslands are home to incredibly rich and diverse plants and insects and are often rare and fragmented. We adapted our maintenance regimes to enhance biodiversity within our sites by creating wildflower areas to enhance our chalk grasslands.
