2. Water well pump - Wikipedia

   en.wikipedia.org/wiki/Water_well_pump

   Deep well pumps extract groundwater from subterranean aquifers, offering a reliable source of water independent of municipal networks. 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.

3. 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 ...

4. Vacuum sewer - Wikipedia

   en.wikipedia.org/wiki/Vacuum_sewer

   Vacuum technology is based on differential air pressure. Rotary vane vacuum pumps generate an operation pressure of -0.4 to -0.6 bar at the vacuum station, which is also the only element of the vacuum sewerage system that must be supplied with electricity. Interface valves are installed inside the collection chambers. They work pneumatically.

5. Groundwater recharge - Wikipedia

   en.wikipedia.org/wiki/Groundwater_recharge

   In 2007, on the recommendations of the International Water Management Institute, the Indian government allocated ₹ 1,800 crore (equivalent to ₹ 54 billion or US$640 million in 2023) to fund dug-well recharge projects (a dug-well is a wide, shallow well, often lined with concrete) in 100 districts within seven states where water stored in ...

6. Submersible pump - Wikipedia

   en.wikipedia.org/wiki/Submersible_pump

   Submersible pump cables are electrical conductors designed for use in wet ground or under water, with types specialized for pump environmental conditions. [5] [6] [7] A submersible pump cable is a specialized product to be used for a submersible pump in a deep well, or in similarly harsh conditions.

7. Deepwater well integrity - Wikipedia

   en.wikipedia.org/wiki/Deepwater_well_integrity

   For example in the South China Sea region, shallow areas usually meet with three shallow problems when drilling in deepwater areas, namely shallow gas, shallow water flow, and natural gas hydrates. [ 4 ] [ 5 ] During drilling operations, complex accidents such as gas invasion and overflow are prone to occur. [ 6 ]
