Southern Water supplies fresh, quality drinking water to almost 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 576 million litres of drinking water from our 95 water treatment works along 13,700 kilometres of water mains to our customers’ taps.

We take nearly 70 per cent of the water from underground sources, called aquifers, 23 per cent from rivers and seven per cent from storage reservoirs.

Each day we also treat and recycle 1.3 billion litres of wastewater at 370 treatment works after it is pumped through a sewer network of more than 39,200 kilometres.

We are owned by Greensands Investments Limited, a consortium made up of pension and infrastructure funds.
