2. Water well pump - Wikipedia

   en.wikipedia.org/wiki/Water_well_pump

   These pumps, often submersible and powered by electricity, can access water reserves located much deeper than shallow wells, ensuring a consistent supply even during periods of drought. They include different kinds of pumps, most of them submersible pumps: Hand pump, manually operated; Injector, a jet-driven pump; Mechanical or rotary lobe pump ...

3. Groundwater recharge - Wikipedia

   en.wikipedia.org/wiki/Groundwater_recharge

   Water balance. Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table ...

4. Well - Wikipedia

   en.wikipedia.org/wiki/Well

   Man cleaning a well in Yaoundé, Cameroon Hand pump to pump water from a well in a village near Chennai in India, where the well water might be polluted by nearby pit latrines. Shallow pumping wells can often supply drinking water at a very low cost. However, impurities from the surface easily reach shallow sources, which leads to a greater ...

5. Comparison of pumps - Wikipedia

   en.wikipedia.org/wiki/Comparison_of_pumps

   Different types of pumps are suitable for different applications, for example: a pump's maximum lift height also determines the applications it can be used for. Low-lift pumps are only suitable for the pumping of surface water (e.g., irrigation, drainage of lands, ...), while high-lift pumps allow deep water pumping (e.g., potable water pumping ...

6. Pumping station - Wikipedia

   en.wikipedia.org/wiki/Pumping_station

   In this configuration pumps are installed below ground level on the base of the dry well so that their inlets are below water level on pump start, priming the pump and also maximising the available NPSH. Although nominally isolated from the sewage in the wet well, dry wells are underground, confined spaces and require appropriate precautions ...

7. Multilevel groundwater monitoring systems - Wikipedia

   en.wikipedia.org/wiki/Multilevel_groundwater...

   An essential design element of all MLS systems is that they must prevent hydraulic connection of the various monitored intervals within the wellbore. [1] While installed primarily in water-saturated sediments and rock, MLS systems can also be installed in the vadose zone for the collection of depth-discrete soil gas samples. Hybrid MLS systems ...

8. Sedimentation (water treatment) - Wikipedia

   en.wikipedia.org/.../Sedimentation_(water_treatment)

   The settling velocity, defined as the residence time taken for the particles to settle in the tank, enables the calculation of tank volume. Precise design and operation of a sedimentation tank is of high importance in order to keep the amount of sediment entering the diversion system to a minimum threshold by maintaining the transport system ...

9. Drawdown (hydrology) - Wikipedia

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

   It is the height of the free surface of water above a given point beneath the surface. [4] Pumping level is the level of water in the well during pumping. [8] Specific capacity is the well yield per unit of drawdown. [8] Static level is the level of water in the well when no water is being removed from the well by pumping. [8]
