What have we done

We have completed a number of schemes to ensure we can make the most effective use of available water.

  • Installed nearly 450,000 new water meters with leak alarms for the majority of our customers. The leak alarms are expected to save up to five million litres of water a day. We have increased the number of water meters from 25 per cent to more than 65 per cent.
  • Improvements to underground boreholes (including Worthing in Sussex, Kettle Hill, Chatham and Cuxton in Kent), such as refurbishments and improved treatment, meaning more water can be abstracted.
  • A £12 million reservoir, which takes water from the River Arun near Hardham, in West Sussex. Water can be abstracted from the river and put into the storage reservoir before being pumped to Hardham Water Supply Works for treatment. It can provide 10 million litres of water per day for Sussex. 
  • Reinforcement of a transfer main between Hardham Water Supply Works and Crawley in West Sussex. This makes it easier to move water around the supply area.
  • A bigger pipeline to supply the Isle of Wight with up to 20 million litres of water a day from the mainland – more than 40 per cent of its demand. The £15 million project involved replacing twin 2km water pipes under the Solent, supplying water from Lepe in mainland Hampshire to Gurnard on the Isle of Wight.
  • A regional water network of pipes to transfer water around the South East. This includes pipes from Bewl Reservoir, in Kent, to Darwell Reservoir, in East Sussex, from Sussex to the Sussex coast and from Medway to Thanet in Kent.
  • A bulk transfer scheme has been set up between us and Portsmouth Water. Up to 15 million litres of water a day can be moved from Portsmouth Water’s Littleheath Reservoir to Whiteways Lodge, near Arundel, and then to our supply works at Hardham.
