Southern Water
Southern Water provides water supply and wastewater treatment services across 4,450 square kilometres from East Kent, through parts of Sussex, to Hampshire and the Isle of Wight.
Raw water is taken from aquifers (70%), rivers (23%) and from storage reservoirs (7%), and each day the company supplies 576 million litres of drinking water from 95 water treatment works along 13,700 km of water mains. The company also operates a sewer network of more than 39,200 km, and every day the company treats and recycles 1.3 billion litres of wastewater at 370 treatment works.
