The Romans absolutely used this technique.

With lead seals in the pipes and aqueduct.

Geniuses, It took us almost 2000 years to figure out how to get that lead airborne.

He may have killed more people than hitler. Lead is now believed to be a significant cause of heart disease

He determined it could be used as a anti knock additive to satisfy some general motors exec who didn't want to use alcohol as a ping inhibitor because of? You guessed it, cost

The auto industry determined in the 50's that lead was a poison. But it took until the 70's for politicians to do anything about it. prop airplanes use fuel that has lead in it to this day.

fire up the gpt and spark up, let's knock it out. I've kinda been lookin out for some crippling debt opportunities 👉👈

Which was totally fine as long as the water wasn’t acidic, which mobilizes the lead

In a cave, with a box of scraps!

Why did the guy in charge of this use a giant bridge instead of the bottom method? Is he stupid?

[–] PugJesus@lemmy.world 60 points 3 months ago* (last edited 3 months ago) (2 children)

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.

[–] tyler@programming.dev 26 points 3 months ago

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.

[–] Iheartcheese@lemmy.world 13 points 3 months ago

But that's the life of a plumbing engineer. When he's not drowning in pussy.

[–] Contravariant@lemmy.world 3 points 3 months ago

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.

[–] Scubus@sh.itjust.works 2 points 3 months ago

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

[–] niktemadur@lemmy.world 13 points 3 months ago (1 children)

There goes my mind again, sliding that dash sideways.

giant ass-water bridge

[–] GBU_28@lemm.ee 11 points 3 months ago

Digging is hard and if it leaks, finding / repairing the leaks is harder.

[–] Anticorp@lemmy.world 6 points 3 months ago

Have you ever dug a ditch? It's fucking hard!

[–] carl_dungeon@lemmy.world 3 points 3 months ago

Because this post is inaccurate, the Romans used both techniques.

[–] timduncant@lemmy.world 3 points 3 months ago

What have the Romans ever done for us?
