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.

If it under crossing or any road not less than 0.80 Meter. And in any place away from roads about 0.5 Meter.
the maximum depth fish can live is 400 meters under water
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.
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.
The equation to calculate water depth is: [ Water Depth = Volume of Water / Surface Area of Water ]
To find the difference between the initial and final depth of water is to subtract the final depth by the initial depth. The initial depth of what is what the water depth starts at and the final depth is the depth of the water once it is finished filling up.
the maximum depth that you can go in the water without a decompression stop is 130 feet. Below 210 feet it is dangerous to dive without mixed gases.AdditionThe maximum depth is not known since people are always trying to break the record. But you must be properly trained and have the necessary equipment. For normal recreational diving, the above answer is absolutely correct and the recommended limit is 130 feet for many good reasons.
Underground water is cleaner.
