Southern Water Services

Our Company

Each day we supply 535 million litres of drinking water from our 90 water treatment works along 13,753 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 700 million litres of wastewater at 368 treatment works after it is pumped through a sewer network of 39,600 kilometres.

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