If you don't take in any liquids for long enough you won't have any urine. It's carried by your blood from source to destination. Your sweat similarly is from liquid transported by your blood

Sounds more like we pee from genitals and skin, with skin being higher priority.

this may be anecdotal, but yes? worked in a high humidity/heat job and no matter how much water i drank, I'd only have to piss once that day

but would sweat so much!

I wonder what the limiting thing was. Was it your body's ability to process the water you were drinking? So, if you'd had more to drink, it might not have been safe? Or was it that your body's thirst signal was turned off, but you still could have processed more water, it just wasn't necessary?

Do you remember if that one piss was dark yellow? I wonder if you were sweating so much that your kidneys were making very concentrated pee because the amount of "unclaimed" water in the blood was low, and most of it was going towards sweating.

That reminds me of going motorcycling in the summer. I was sweating buckets, but as soon as my body squeezed out a drop of sweat, it was immediately whipped off by 100 km/h winds. I remember drinking crazy amounts of water, and being surprised that I didn't pee nearly as much as I was drinking. But, I still think I was peeing more than once per day.
