All over the world, graves are made at about the same depth - 2 meters. This standard has its own reasons, originating in ancient times.
In 1655 Great Britain suffered from the bubonic plague. The Black Death mowed down the entire country, especially large cities with a high concentration of the population suffered. London was suffocating under the yoke of thousands of bodies, no one knew what to do with the dead.
The decision of the City of London to bury the dead at a depth of 6 feet made it possible to arrest the sources of infection. 6 feet is about 2 meters. Over time, such a standard spread throughout the world, and is still used today.
In our country, according to GOST R 54611-2011 (yes, there is one!), The maximum depth of the pit should not exceed 2.2 meters, so as not to accidentally get to the groundwater.
The minimum pit depth is at least one and a half meters. And yes, this is also regulated by GOST.
