Our reservoirs offer a range of facilities from walking and biking to sailing and bird watching.


We operate four key reservoirs across the South East which store vital drinking water supplies. Some also have public access – read more about the reservoirs below.

  1. Bewl Water 
    • The largest of the reservoirs is Bewl Water, located near Lamberhurst on the Kent/Sussex border. 

      Find out more information on Bewl Water and its extensive leisure facilities.
  2. Weir Wood 
    • Weir Wood Reservoir, near East Grinstead, in West Sussex, has a number of activities including sailing which is organised through Weir Wood Sailing Club.

      The Millennium Walk footpath runs from the water treatment works at the reservoir and joins a public footpath along the fence line, with a picnic site offering spectacular views across the water about one kilometre west of the works. 

      Parking is available – marked in red on our map of Weir Wood Reservoir – for access to the Millennium Walk footpath only. Please note this is an operational site and is in use by staff 24 hours a day.

  3. Darwell 
    • Darwell Reservoir, near Battle, in East Sussex, has public rights of way through the woodland that surrounds the site.

      There is no public car park available at Darwell.
