The South East includes the counties of Berkshire. Buckinghamshire, Hampshire, the Isle of Wight, Kent, Oxfordshire, Surrey, East Sussex, and West Sussex. So are these areas primarily supplied by hard or soft water? Let’s take a look!
What is the scale of hardness?
We can categorise water hardness into 3 different groups, the ppm stands for parts per million and refers to the amount of calcium carbonate and magnesium present in the water:
Soft to moderately soft water – 1 -100ppm
Medium to moderately hard water- 100-200ppm
Hard to very hard water – Over 200 ppm
Water is hard when it runs through or sits in areas with high mineral content. Water taken from certain sources is much more likely to be hard. Groundwater sources such as underground aquifers are a prime example of a hard water source.

Which Water suppliers are active in this region?
There are 8 different water suppliers across the South East region. We’ll take a quick look at each of them and where they source their water from.
Affinity Water: Over 60% of Affinity’s water is sourced from groundwater taken directly from Aquifers. The remaining water comes from the Thames.
Anglian Water: Anglian water sources 50% of its supply from rivers and above ground reservoirs and the other 50% from underground reservoirs and aquifers.
Portsmouth Water: Portsmouth water gets almost all of its supply from the chalk aquifer of the South Downs.
Southern Water: 70% of Southern waters supply comes from chalk aquifers another 23% from rivers and the final 7% from surface water reservoirs.
South East Water: South East water mostly uses groundwater from boreholes and wells with the rest coming from rivers and surface reservoirs.
Sutton and East Surrey: Water: 85% of SES Water comes from the North downs Chalk Aquifers, the rest is sourced from their Bough Beech reservoir.
Thames Water: Thames waters supply is sourced 56% from rivers and 35% from aquifers.
Wessex Water: 80% of Wessex Water’s supply comes from underground aquifers with the rest coming from surface reservoirs.
The South East has some of the hardest water in the country on account of the prevalence of chalk Aquifers as a water source. Every county in the South East is supplied with water in the Hard to very hard category. If you are moving to the South East or already live there and are fed up with the limescale you may want to look into a way to treat your water.
