Present Day
Most of London's water still comes from the River Thames and River Lea, with the remainder being abstracted from underground sources.
Much of the water piping in London is still cast iron piping which dates back to the nineteenth century and is slowly deteriorating. This has led to widespread criticism of Thames Water for the amount of water lost to leaks in its distribution network. As of 2007, Thames Water is still in the process of a rolling programme of upgrading the water supply network to use modern plastic piping.
The single largest infrastructure project in recent years has been the creation of the Thames Water Ring Main, a "backbone network" for London's water supply. This connects all the waterworks, and pumping stations.

Famous quotes containing the words present day, present and/or day:
“The East knew and to the present day knows only that One is Free; the Greek and the Roman world, that some are free; the German World knows that All are free. The first political form therefore which we observe in History, is Despotism, the second Democracy and Aristocracy, the third, Monarchy.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
“There is not any present moment that is unconnected with some future one. The life of every man is a continued chain of incidents, each link of which hangs upon the former. The transition from cause to effect, from event to event, is often carried on by secret steps, which our foresight cannot divine, and our sagacity is unable to trace. Evil may at some future period bring forth good; and good may bring forth evil, both equally unexpected.”
—Joseph Addison (1672–1719)
“The phenomena of the year take place every day in a pond on a small scale. Every morning, generally speaking, the shallow water is being warmed more rapidly than the deep, though it may not be made so warm after all, and every evening it is being cooled more rapidly until the morning. The day is an epitome of the year. The night is the winter, the morning and evening are the spring and fall, and the noon is the summer. The cracking and booming of the ice indicate a change of temperature.”
—Henry David Thoreau (1817–1862)
