MORE INFORMATION

The Three Valleys area suffered its worst drought since 1976, with two exceptionally dry winters and consistently below-average monthly rainfall between November 2004 and September 2006.

But above-average rainfall enabled the company to lift restrictions in January 2007, although it is urging customers to continue to use water sparingly because of fears of another drought later in the year.

Most of the company's supply comes from deep chalk boreholes which produce naturally hard water from aquifers. A further third comes from the River Thames.

Three Valleys Water, along with Folkestone and Dover Water and Tendring Hundred Water, is owned by Veolia Water.
