Cistern in the Mission District, San Francisco, California. The Auxiliary Water Supply System (AWSS, though often referred to on manhole covers and hydrants as HPFS for High Pressure Fire System) is a high pressure water supply network built for the city of San Francisco in response to the failure of the existing emergency water system during the 1906 earthquake.
Portuguese cistern (Mazagan), El Jadida, Morocco (1514) The difference between a cistern and a well is in the source of the water: a cistern collects fresh water where a well draws from groundwater. A cistern (from Middle English cisterne ; from Latin cisterna , from cista 'box'; from Ancient Greek κίστη ( kístē ) 'basket' [ 1 ] ) is a ...
Commonly, the catchment area, known as an agor, is a concave cemented funnel-like slope directing water into a collection pit that reduces the sediment load of water before it enters the underground cistern via a suitable mesh supported by bars in an angle iron frame to filter out other large debris.
An elevated water tank, also known as a water tower, will create a pressure at the ground-level outlet of 1 kPa per 10.2 centimetres (4.0 in) or 1 psi per 2.31 feet (0.70 m) of elevation. Thus a tank elevated to 20 metres creates about 200 kPa and a tank elevated to 70 feet creates about 30 psi of discharge pressure, sufficient for most ...
An exploded-view drawing is a diagram, picture, schematic or technical drawing of an object, that shows the relationship or order of assembly of various parts. [1]It shows the components of an object slightly separated by distance, or suspended in surrounding space in the case of a three-dimensional exploded diagram.

The Cisterns of Tawila, or the Tawila Tanks, is a historic site in Aden, Yemen designed to collect and store the rain that flows down from the Shamsan massif through Wadi Tawila, and to protect the city from periodic flooding.
The Union Watersphere is a water tower topped with a sphere-shaped water tank in Union, New Jersey, [11] and characterized as the World's Tallest Water Sphere. A Star Ledger article [ 12 ] suggested a water tower in Erwin, North Carolina completed in early 2012, 219.75 ft (66.98 m) tall and holding 500,000 US gallons (1,900 m 3 ), [ 13 ] had ...
The water is typically pressurised by pumping the water into storage tanks constructed at the highest local point in the network. One network may have several such service reservoirs. In small domestic systems, the water may be pressurised by a pressure vessel or even by an underground cistern (the latter however does need additional pressurizing).
