Why did the guy in charge of this use a giant bridge instead of the bottom method? Is he stupid?
Digging used to be much more expensive, and calculating pressure much dicier. The Romans used the pressure method over short distances, with reliable piping (noting that pipes under high pressure would need to be sealed with earth or concrete), but over large distances, it was easier just to make a giant-ass water bridge and ensure it was sturdy.
Plumbing engineer here. Digging is still fucking expensive.
I dug like an 8 inch hole next to my walkway the other day and it took like 5 hours and I didn’t accomplish what I wanted.
But that's the life of a plumbing engineer. When he's not drowning in pussy.
When it comes to DIY I'm not touching anything remotely similar to something Colin Furze would make a video about.
So far that rule of thumb seems to hold up quite well.
Oh please, I dug a 6 inch wide, 1 foot deep hole yesterday and outside of the cost of the shovel it cost me nothing. People these days just don't want to work /s
There goes my mind again, sliding that dash sideways.
Relevant xkcd
Digging is hard and if it leaks, finding / repairing the leaks is harder.
Have you ever dug a ditch? It's fucking hard!
Because this post is inaccurate, the Romans used both techniques.
