2. Water aeration - Wikipedia

   en.wikipedia.org/wiki/Water_aeration

   Water aeration. Fountains aerate water by spraying it into the air. Water aeration is the process of increasing or maintaining the oxygen saturation of water in both natural and artificial environments. Aeration techniques are commonly used in pond, lake, and reservoir management to address low oxygen levels or algal blooms.

4. Submersible pump - Wikipedia

   en.wikipedia.org/wiki/Submersible_pump

   A submersible pump (or electric submersible pump (ESP) is a device which has a hermetically sealed motor close-coupled to the pump body. The whole assembly is submerged in the fluid to be pumped. The main advantage of this type of pump is that it prevents pump cavitation, a problem associated with a high elevation difference between the pump ...

5. Underwater environment - Wikipedia

   en.wikipedia.org/wiki/Underwater_environment

   Great Barrier Reef, Australia. An underwater environment is a environment of, and immersed in, liquid water in a natural or artificial feature (called a body of water), such as an ocean, sea, lake, pond, reservoir, river, canal, or aquifer. Some characteristics of the underwater environment are universal, but many depend on the local situation.

6. Water pumping - Wikipedia

   en.wikipedia.org/wiki/Water_pumping

   Water pumping. The pumping of water is a basic and practical technique, far more practical than scooping it up with one's hands or lifting it in a hand-held bucket. This is true whether the water is drawn from a fresh source, moved to a needed location, purified, or used for irrigation, washing, or sewage treatment, or for evacuating water from ...

7. Pumped-storage hydroelectricity - Wikipedia

   en.wikipedia.org/wiki/Pumped-storage...

   A pumped-storage hydroelectricity generally consists of two water reservoirs at different heights, connected with each other. At times of low electrical demand, excess generation capacity is used to pump water into the upper reservoir. When there is higher demand, water is released back into the lower reservoir through a turbine, generating ...
