  2. Underground storage tank - Wikipedia

    en.wikipedia.org/wiki/Underground_storage_tank

    "Underground storage tank" or "UST" means any one or combination of tanks including connected underground pipes that is used to contain regulated substances, and the volume of which including the volume of underground pipes is 10 percent or more beneath the surface of the ground. [1]

  3. Drawdown (hydrology) - Wikipedia

    en.wikipedia.org/wiki/Drawdown_(hydrology)

    Static level is the level of water in the well when no water is being removed from the well by pumping. [8] Water table is the upper level of the zone of saturation, an underground surface in which the soil or rock is permanently saturated with water. [9] Well yield is the volume of water per unit time that is produced by the well from pumping. [8]

  4. Specific storage - Wikipedia

    en.wikipedia.org/wiki/Specific_storage

    is the mass of water released from storage ([M]); and is the decline in hydraulic head ([L]). Volumetric specific storage (or volume-specific storage) is the volume of water that an aquifer releases from storage, per volume of the aquifer, per unit decline in hydraulic head (Freeze and Cherry, 1979):

  5. Storage tank - Wikipedia

    en.wikipedia.org/wiki/Storage_tank

    Capacity table for horizontal cylindrical storage tank [3] In order for volume measurements from the tank to be used, it typically has a capacity table created using appropriate standards. [3] Each row of capacity table contains fill level value and corresponding volume value (and other related data).

  6. Water tank - Wikipedia

    en.wikipedia.org/wiki/Water_tank

    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 ...

  7. Stormwater detention vault - Wikipedia

    en.wikipedia.org/wiki/Stormwater_detention_vault

    A stormwater detention vault is an underground structure designed to manage excess stormwater runoff on a developed site, often in an urban setting. This type of best management practice may be selected when there is insufficient space on the site to infiltrate the runoff or build a surface facility such as a detention basin or retention basin .

  9. Groundwater flow equation - Wikipedia

    en.wikipedia.org/wiki/Groundwater_flow_equation

    Used in hydrogeology, the groundwater flow equation is the mathematical relationship which is used to describe the flow of groundwater through an aquifer.The transient flow of groundwater is described by a form of the diffusion equation, similar to that used in heat transfer to describe the flow of heat in a solid (heat conduction).
