Balancing Lake

A balancing lake (also "flood basin") is a term used in the U.K. describing an element of an urban drainage system used to control flooding by temporarily storing flood waters. The term balancing pond is also used, though typically for smaller storage facilities for streams and brooks.

In open countryside, heavy rainfall soaks into the ground and is released relatively slowly into watercourses (ditches, streams, rivers). In an urban area, the extent of hard surfaces (roofs, roads) means that the rainfall is dumped immediately into the drainage system. If left unchecked, this will cause widespread flooding downstream. The function of a balancing lake is to contain this surge and release it slowly. Failure to do this, especially in older settlements without separate storm and foul sewers, can cause serious pollution as well as flooding.

Famous quotes containing the words lake and/or balancing:

    Wordsworth went to the Lakes, but he was never a lake poet. He found in stones the sermons he had already hidden there.
    Oscar Wilde (1854–1900)

    Men are to be guided only by their self-interests. Good government is a good balancing of these; and, except a keen eye and appetite for self-interest, requires no virtue in any quarter. To both parties it is emphatically a machine: to the discontented, a “taxing- machine;” to the contented, a “machine for securing property.” Its duties and its faults are not those of a father, but of an active parish-constable.
    Thomas Carlyle (1795–1881)
