What is the reason for laying the circulating water main pipes and fire protection pipes underground?

As the title suggests, the pipes are too large, resulting in high costs for overhead installation; they are non-toxic and harmless, pose little risk when buried, and this approach is also taken to prevent freezing in winter. I’m not sure if it’s due to these reasons
It’s not easy to be hit by tractors when buried; only an excavator can break it apart with a single shovel strike
You’ve almost run out of answers. . . Another point is that for general circulation water pumps, those with high flow rates and low head pressures are usually chosen. If the pump is to be installed on a pipe rack, it becomes necessary to increase the pump’s head pressure; however, some pumps with high flow rates but high head pressures may not be suitable choices
