When do we run out of drinkable/potable water?

I don't know why, but since I was a kid I always worry that we will run out of water, we seem to waste it, heavily...watering lawns, extra long showers, dripping faucets, etc.

It is the only thing that really makes me scared, just think...no pottable/drinkable water, insane chaos would ensue.

? It's not like water just dissapears after you take a shower and can never be used again.
 
This is true.

Are you saying the water wasted in a long shower goes back and potentially gets reused?

Yeah. Especially if you have a septic system. You use energy to pump water out of the ground from your well. Then you flush the toilet and take a shower and it goes into your septic system, then the leach field, and then it drains right back into your well where it came from.

Not in big cities, no?

What about acid rain though? Is that usable/reusable even?
 
It goes into the drain for a shower, but watering lawn, pools, that sort of thing?

It all goes back to the water supply eventually through various means -- evaporation, sinking through the ground and back into the water table, sweat evaporating (in the case of animals), etc.
 
Depends on where you live. East coast is pretty good on water. They're already short out west, and it isn't getting replaced as fast as it's being used.
 
Same thing with food, eventually we are going to eat all of it. Anyone know any projected dates when all the food runs out?
 
You live in Minnesota and worry about running out of water? You'll run out of mosquitoes before you run out of water.
 
For perspective, the US draws about 450 billion gallons per day for consumption Roughly 300 billion gallons of water pass by New Orleans each day through the Mississippi River.
 
Dammit, Vivi, now you've got me worried. What about air? That's gotta run out at some point, too, right?

It's a real problem. With the advent of hot air poppers much of our air is being locked up in popcorn. Not to mention hair dryers.
 
FUD-victim.

also, maybe time to revisit elementary school and learn about the water cycle. where do you think the water you water your lawn with goes?

we know how to distill, desalinate, purify and filter water. hell, we even can create pure H2O as a byproduct of combining hydrogen and oxygen in a fuel cell.

there may be a day where we cant drink water unless its been processed in one of those fashions, but to think we would ever pollute ourselves out of existence is retarded. i dont think there is a word to describe the thinking that water disappears forever unless it goes down a drain...
 
The earth is two-thirds water.
Reverse osmosis works.
We just need to figure out large scale production.

Dump the salt back in the sea, let the fresh water drain back in after we use it.

Oh, and for those of you who dont know: Drinking H2O will kill you.

Water filtration isn't a cheap process. There's places in the world that already can't deal with the pollution, and in the first world, we have energy production issues. Wasting water is how retards deal with the problem.
 
Apparently sometime in the last year. Turns out my municipal water has unsafe levels of lead and other carcinogens in it.

Nice. Considering I have 5 kids at home.

Even knowing this, I still worry!!
