[2] [3] It consists of five concrete containment silos with heights of 65 metres (213 ft) and diameters of 32 metres (105 ft), connected by 6.4 kilometres (4.0 mi) of tunnels, 50 metres (160 ft) beneath the surface, as well as a large water tank with a height of 25.4 metres (83 ft), with a length of 177 metres (581 ft), with a width of 78 ...
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 ...
FRP tanks and vessels designed as per BS 4994 are widely used in the chemical industry in the following sectors: chlor-alkali manufacturers, fertilizer, wood pulp and paper, metal extraction, refining, electroplating, brine, vinegar, food processing, and in air pollution control equipment, especially at municipal waste water treatment plants and water treatment plants.
Tanks built below ground level are sometimes used and referred to as underground storage tanks (USTs). Reservoirs can be covered, in which case they may be called covered or underground storage tanks or reservoirs. Covered water tanks are common in urban areas. Tanks can be mounted on a lorry or an articulated lorry trailer.

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 ...

Water located beneath the ground surface An illustration showing groundwater in aquifers (in blue) (1, 5 and 6) below the water table (4), and three different wells (7, 8 and 9) dug to reach it. Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in ...
Most of the solids are removed by the interceptor tanks, so the treatment plant can be much smaller than a typical plant and any pumping for the supernatant can be simpler without grinders (sometimes water pumps are sufficient). An alternative effluent sewer which is similar to the STEG system is the STEP system.
