MUST READ Re-purposing air-con water # 3

Personally, I would highly recommend that this water is only used for flushing toilets, doing laundry or watering non-edible plants (which are nowhere near a veggie bed / fruit tree)

Answer Wiki

A majority of answers state no. Reasons include bacterial and possible heavy metal contamination.

A minority of answers also point out that condensate is almost de-ionised, making it less than ideal for sustenance.

In engineering parlance, condensate is equivalent to rain water in terms of cleanliness: boil first.

1 Well, it's not wastewater. It's condensate.
While water condensed from the air is distilled, the collection leaves a lot to be desired. The coils where it condenses and the drip pans that catch it are not kept clean and is a breeding ground for various molds and bacteria.

If you have a typical years old house the A/C drain pan and plumbing gets dusted once a year and sterilized… never.

I would strongly advise not drinking it.

I know for a fact that if I don't dump a cup of bleach into the condenser pan every few months the the black slime mold will clog up the drain and cause an overflow and leak. Same black slime you get on the nozzles of ice and soda machines at restaurants if they don't keep it clean.

2  But I would like to add that Legionnaires' disease can live in AC's.  There is some belief that drinking water from an AC can cause the disease, if you inhale any of it while drinking it.  Of course the risk of this being in your home is rare.  

Another thing to add is that your AC coil is a very dirty place.  

Here is a picture of one that is not that uncommon.

I would not drink anything that dripped out of this.  

Bare in mind that all the dust you have in your house goes through this cooling coil.  Sloughed off skin cells, pet dander, cooking vapors and anything else air born.  Add water to this mix and you get all sorts of mold and bacteria.

3 I wouldn’t drink it without treatment, because it might contain lead or other metals (from the drip pan) or legionella bacteria (from constant damp). My uncle, though, piped his to a flowerbed. Living in central Louisiana, with about a 2,300 sq ft house, he produced about fifteen gallons a day.
