Bewl Water is a reservoir in the valley of the River Bewl (which is a tributary of the River Teise), straddling the boundary between Kent and East Sussex. It is about 4 km south of Lamberhurst, Kent, England. The reservoir was part of a project to increase supplies of water in the area. It supplies not only Southern Water’s customers in the Medway towns, Thanet and Hastings, but is also used by other water companies in the area.
Work began to construct the reservoir in 1973 by damming and then flooding a valley. It was completed in 1975 having been filled with over 31,300 million litres of water. It is now the largest body of inland water in south east England.
