2. Introduction

SWS supply water to more than one million homes and businesses in Kent, Sussex, Hampshire and the Isle of Wight.

Most of the region is officially classed as ‘water-stressed’, which means that at times the demand for water can be higher than the amount available. However, each county also has different water sources and experiences different weather. It's not unusual for one area to be in drought while supplies are normal in a neighbouring area. The map in Figure 1 (below) shows where we supply water and the average amount of water used. We divide the area into 14 ‘water resource zones’.
