where does the tap water in london come from
London water supply infrastructure Most of London's water comes from non-tidal parts of the Thames and Lea, with the remainder being abstracted from underground sources.[22]
Port of London The Port of London lies along the banks of the River Thames from the capital to the North Sea. Once the largest port in the world, it is currently the United Kingdom's second largest port, after Grimsby & Immingham. The port is governed by the Port of London Authority (PLA), a public trust established in 1908 whose responsibility extends over the Tideway of the River Thames, but which neither owns or operate any facilities.
