Water is generally not harmful unless inhaled (drowning) as noted.
As with many things there are some exceptions to the rule.
De-Ionized Water (DI water) is ultra purified water. Water is a solvent so the potable water we normally consume generally has a lot of minerals and stuff dissolved in it making it relatively benign.
Because DI water is so pure its a pretty aggressive solvent which can readily dissolve and corrode plastics, metals and even stainless steel more so than regular water.
Note the link to the MSDS (Material Safety Data Sheet) First Aid for ingestion is to seek medical treatment if irritation or symptoms occur.
So DI water could give you an upset stomach or worse depending on how much you ingest. If not chemically hazardous there may be a biological hazard as DI water is NOT treated with chlorine or otherwise for human consumption.
DI water will readily leach metals and chemicals from piping and containers, concentrations of these materials maybe be in higher concentrations than allowable drinking water standards. The DI system in the lab at work has a conductivity meter on it. We flush the line to clear water that has been sitting in the pipes until the conductivity drops. (red vs. green led so I can't quantify the conductivity value other than go/no go)

It is a shame that people are so poorly educated in science these days that a little joke can cause panic.
The really bad part is that some of the ignorant pseudo chemical ideas are finding their way into regulatory language in the USA. I mean words like "calory," "solvent," "organic" and "all natural."
Water is a solvent (in fact it is sometimes called the "universal solvent") and everyone knows that solvents are really dangerous chemicals.
What's wrong with "calory," you say? As used in nutritional labels, it is 1000 times the value of the scientific one. I think that the ag department and HEW decided that people are too stupid to know what a Kilocalory is.
I hear that some polititians want to ban Carbon dioxide. Whoops, there goes all green plant life and other living things that depend on it. This will really help the planet, though.

The "DiHydrogen Oxide" moniker came from a (very, very smart) 14-year-old Junior High School kid who got hundreds of people to sign a petition calling for this 'dangerous' substance to be banned! After all, it will cause death if inhaled, and causes almost everything it touches to corrode. The kid wanted it banned because "big corporations" were using it as an ingredient in baby food!
His point was to highlight how even many adults are ignorant of the simplest concepts in science.
Given that, here are some entertaining links: (top link is to the Snopes.com history of this)
Enjoy!

While others have said that it is not toxic, consuming too much water in any form can kill you (we're talking gallons here) as it strips away electrolites and other minerals that are essential for your survival. Learned this the hard way my first 24 hours in an overseas desert. Drank so much water that I was told the reason I didn't feel well was I was drinking too much. Did a quick web search to back my statement and it is found below.

Legends and artifacts dating back thousands of years have ignited man's imagination for decades to centuries with theories of ancient astronauts and alien beings from other planets. Sightings of "UFOs" or "unidentified flying objects" of varying sizes, shapes and other characteristics have been recorded around the world for hundreds of years, possibly thousands. In popular TV shows, it is claimed that "sky people" are purportedly recorded as having brought advanced culture to the hominids who have lived on this planet. According to these legends, supposedly, this "first contact" had occurred previously, following cataclysm. Some stories relate this civilizing event to have happened several times during Earth's history. Geological, paleontological, anthropological and archaeological data reveal that there have indeed been many cataclysms on this earth, several on a global level, with climate change and mass extinction. The tales allegedly recount that after such a catastrophe, many surviving humans were reduced to the Stone Age but that more advanced humanoids descended from spacecraft and reestablished civilization. Are these claims true? Were these "sky people" aliens? Have there been "aliens" among us all along? Or is it all just an illusion?

There is a common joke among chemists about the dangers of "Dihydrogen monoxide." Dihydrogen monoxide does kill thousands of people every year (by drowning).
The joke lies in recognizing that in the nomenclature rule for a non-metal to a non-metal, you are supposed to name each atom contained in the compound's molecular formula with a prefix indicating how many of each atom are contained in the molecule (mono-, di-, tri-, etc.)
With water, the technical name for it is dihydrogen monoxide. Many people fall for the joke initially because of the tendency of people to readily accept that anything that sounds like a chemical is, in fact, toxic. This joke's ability to fool someone is indicative of the scientific ignorance of the person falling for it.

Pure water is not at all poisonous. If u drink it twice or thrice its not a problem. but' if u go on drinking it as u drink water normally u can have problems. Bcoz normal drinking water has essential dissolved salts in it which maintains the electrolyte balance of the body.
But pure water can drain dissolve all the minerals and electrolytes of ur body and can affect ur health. So, pure water is not poisonous but excess of it can cause elctrolyte imbalances in ur body.

"Pure" water is composed of H20, OH- and H3O+ in equilibrium at a PH of 7.0. However, it's virtually impossible to remove ALL impurities from water, even when going through multiple distillations and the best filters made. But no, it's not toxic.
Hydrogen dioxide would be HO2, not H2O and would be a completely different molecule if it could even exist.

No. H2O in it's purest form is only toxic if inhale it instead of drink it.
By the way, water has many other names, Hydrogen Hydroxide, Hydric Acid, Diydrogen Monoxide, and many, many more...
water is water...
Oh, and by the way, regarding the post below... urine is sterile and is no more poisionous than a tear or saline solution... (unless the person has some sort of urinary infection)

Pure water is non-toxic. You can drown in it, but that is not poisoning. It is asphyxiation.
