About us

Each day we supply 529 million litres of drinking water from our 90 water treatment works along 13,735 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 730 million litres of wastewater at 368 treatment works after it is pumped through a sewer network of 39,000 kilometres.

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