Cambridge Water Company
Boreholes drilled into the chalk strata south of Cambridge provide 97% of the water, while 3% comes from a greensand source to the west which feeds Gamlingay and the surrounding villages. Cambridge Water operates 23 water treatment works that process 73 million litres of water per day, supplying 300,000 people through 2,300km of water mains.
In 2013 CWC was acquired by South Staffs Water.
