Using portable toilets to save water
Athens Family Dental Center (located in Athens, GA) has come up with a unique way to cut back on water — they’ve installed two portable toilets in their parking lot for their 30 employees and seven doctors to use. They still allow patients to use the regular toilets. Seems like a pretty good way to cut back on water usage. Assuming two flushes per day per person at about three gallons per flush, they’re saving about 6,600 gallons of water per month
Another way to save the same amount of water would be to install a gray water system, but I have to imagine the portable toilets were far less expensive.
In the event that Atlanta goes dry, I would expect a mad rush on portable toilets since all of the normal toilets would no longer flush. Maybe it’s time to invest some money in a Porta-Potty company?

A cheap greywater system for home use is the bathtub and a small bucket. An additional big bucket will make life easier.
1) Put plug in bathtub drain
2) take morning showers (assuming your shower is not sperate from bathtub)
3) use water from tub to flush toilet
4) use the big bucket to hold extra water, so you don’t have to stand in cold water next morning
This has been done for years in San Francisco during their frequent drought years.
