Piping systems are prevalent throughout our everyday world. Most
of us think of piping systems as underground structures used to
convey liquids of one sort or another. To the novice, the concept
of pipeline installation underground sounds relatively straight
forward: a) dig a trench, b) lay the pipe in the trench, and c) fill the
trench back in.

the maximum depth fish can live is 400 meters under water
The recommended depth for burying a 1 inch PEX underground water line is at least 18 inches to protect it from damage and freezing.
Loch Morar with a maximum depth of 310 m. Loch Ness is second with a maximum depth of 132 m.
Not a plumber however I do know it varies buy region. You need to know the depth of the freeze line in your area. That will determine the depth to install your hydrant.
PADI -> 60 Ft or 18.3 M
Excessive water pressure at depth would implode the Sub destroying it and all soles within.
Depth of water
The wave base is the maximum depth at which waves cause significant water motion. Below the wave base, water is relatively undisturbed by wave action. The depth of the wave base is determined by the wavelength of the waves.
To determine the maximum depth at which a wave will not be refracted, we can use the rule of thumb that the water depth should be at least half the wavelength. If the wavelength is ( \lambda ) meters, the critical depth for minimal refraction would be ( \lambda / 2 ) meters. Therefore, a wave will not be refracted in water with a depth greater than ( \lambda / 2 ) meters.
Underground water is called underground water, because it is "underground" not because it is fresh or salt. You can have underground salt water reservoirs just like you can have fresh water ones.
Underground water is cleaner.
The equation to calculate water depth is: [ Water Depth = Volume of Water / Surface Area of Water ]
