Water pipes are typically placed underground to protect them from environmental factors and physical damage. They are often located beneath roadways, sidewalks, and private property, running parallel to the street. In some cases, pipes may also be installed above ground in areas where underground placement is impractical. Proper placement ensures accessibility for maintenance while minimizing disruption to surface activities.

In general, water in underground pipes is less likely to freeze compared to above-ground pipes because the surrounding soil acts as insulation. However, in very cold climates or if the pipes are not buried deep enough, there is still a possibility for the water to freeze. Insulating the pipes properly can help prevent this from happening.
No, soil pipes should not be laid above ground. Soil pipes should be installed within the building structure and connect to the sewer or septic system underground to ensure proper drainage and sanitation. Above ground installation can lead to leaks, odors, and potential health hazards.
how to identify grade of G.I pipe ?
I have worked on wells for years and never found any well frozen ( I live in Canada and it does get very cold here). You are possibly referring to well water that has been pumped to the surface and is in pipes or a tank. We keep all well pipes under ground at least 18 inches and insulate the pipes when they come above ground level. This is essential in any area that drops below '0' at all.

Well, it's really a great questions. As for the black pipes, it's because during the manufacturing process, some materials are added to pretect the pipe, ususlly to anti-UV.

Justi like RIIFO's PPR pipes that are usually green.
The damage from an earthquake can destroy underground electric mains and water pipes as a hurricane only forms above surface and can not destroy nothing under the surface and can only effect above ground level
The Empire State Building primarily utilized cast iron pipes for its above-ground drainage systems. Cast iron was favored for its durability and resistance to corrosion, making it suitable for handling wastewater and stormwater. Additionally, some sections may have incorporated alternatives like PVC or other materials, but cast iron remained the predominant choice during the building's construction in the 1930s.
