Supply source: 31% surface, 69% ground
RESTRICTION LEVEL
Hosepipe ban introduced in all supply zones except Hampshire - the earliest in July 2005 - but after above-average rainfall in late 2006, the restrictions were lifted on 18 January 2007.
Non-essential use drought orders were granted for Southern Water's Kent and Sussex zones on 25 May 2006, although the company held off implementing them because it said supplies were sufficient.
MORE INFORMATION
About 70% of Southern Water's supply comes partly or wholly from ground sources and the region's second-driest winter since 1904 depleted levels in the aquifers - underground reserves.
Although none of the company's four available reservoirs is fully recovered yet, the company believes there has been sufficient rain to enable it to lift the long-standing restrictions, especially as it has stepped up its efforts to combat leakage.
Southern Water treats waste water from a larger area than it supplies with drinking water.
