In the document, which covers the period from 2020 to 2080, South East Water said it was looking ahead 60 years despite environmental and economic regulators only requiring a plan until 2045 because of the challenges of operating in a water-stressed area, with population in its supply area forecast to grow by 53% to 3.34 million by 2079/80.

While reducing leakage and encouraging less water consumption play a significant role in the company's plans, there are a number of larger-scale proposals for the 2020-2045 period, which include:

  • Building a new water treatment works at the former Aylesford Newsprint site, Kent, by 2023
  • Upgrading existing water treatment works at Ford WTW in east Kent by 2027
  • Developing a water reuse scheme at Peacehaven, East Sussex, by 2028
  • Building a new reservoir next to its existing Arlington reservoir in East Sussex by 2032
  • Creating a new reservoir in Broad Oak, Kent by 2033
  • A water re-use scheme at Aylesford, Kent, by 2038
  • Developing a regional water transfer scheme from SES Water

Long-term considerations for the 2045-2080 period are:

  • Desalination at Eastbourne, Reculver and the River Medway
  • Water re-use on the River Stour, east Kent
  • A new reservoir in West Sussex
  • New raw water abstraction and treatment works from the River Thames near Maidenhead, Berkshire
  • Regional water transfers from Portsmouth and Thames Water
  • A new groundwater resource near Farnborough, Hampshire

The company said in the document: "Over the 60-year planning period we estimate that the current cost of our plan will be £1053.9M in net present value (NPV) terms and will increase the supply of water by 294.2 Ml/d."

Residents are now being encouraged to provide feedback on the draft plans over a 12-week period.

South East Water's Head of Water Resources, Lee Dance, told local media: "We are looking far into the future, right to 2080, to make sure we have a secure and resilient water supply for homes and businesses, while also balancing the needs of the environment and keeping customers’ bills down. 

"The draft plan represents a £1BN investment in water supply infrastructure and has been developed with input from customers, communities, other water suppliers and our stakeholders."
