Well that was quick. Just back in January the water levels in Lake Michigan were nearing an all-time low. Now, mainly because of the large rainstorms that caused flooding havoc in the area, our main weatherman Tom Skilling is reporting that the lake is now 8 inches above where it was last year at this time. While that might not seem like much, because of the lake's size that adds up to a staggering 3.1 trillion gallons of water. Chicago uses approximately 1 billion gallons of water per day.




I wonder how many toilets use those 1 billion gallons of water, hmmmmm. Time for toilet math.
Typical Toilet = 1.28 gal/flush
Chicago water usage = 1,000,000,000.00 gallons of water.
Estimate Usage for Toilets = 212,500,000.00 gallons (I pulled this out of my head.)
EUT/TT = 166,015,625 toilets.
Of course these are pretty wacky estimates, given that not all toilets are created equal in capacity, water usage, and/or type. But still, gosh that is a lot of toilets.
The lake is still at historical lows...
@sumsinnow It would seem to me that your formula calculates total number of flushes, not toilets. But what do I know, I'm no math whiz. (HA!)
lol@prescott.hahah
@sumsinnow, unfortunately 1.28 is closer to a urinal flush. The ultra low flow toilet mandated federally is at 1.8 gallons per flush and any toilet made before 1995 ranges from 3.5 to 7 gallons.
heh, yeah, calculating flushes.. I think I'll stick to taking pictures. :)
