Southern Water supplies fresh, quality drinking water to more than one million households and treats and recycles wastewater from nearly two million households across Sussex, Kent, Hampshire and the Isle of Wight.

Each day we supply 555 million litres of drinking water from our 90 water treatment works along more than 13,600 kilometres of water mains to our customers’ taps.

We take nearly 69 per cent of the water from underground sources, called aquifers, 26 per cent from rivers and five per cent from storage reservoirs.

Each day we also treat and recycle 1,300 million litres of wastewater at 371 treatment works after it is pumped through a sewer network of more than 21,500 kilometres.

Southern Water is owned by Greensands Investments Limited, a consortium made up of pension and infrastructure funds.
