Apart from cavilling at the wording (surely it is almost the definition of "too much" that it can be harmful!), this article highlights something that is so very important. Lots and lots of water is not good for us.
For a change, it is the "medicial advice" that is criticised rather than patients. So who was responsible for the poorly worded advice that sends the wrong message. We should be told!!!
Drinking too much water when ill can be harmful, finds study
Doctors warn excessive intake can pose risks for some patients and say medical advice needs to be more specific
The common advice to drink plenty of water when ill is based on scant evidence and can actively harm chances of recovery, doctors have warned.
Medics at King’s College hospital NHS foundation trust, in London, raised the alarm after they treated a patient with hyponatremia – abnormally low sodium – from drinking too much water to help with a recurring urinary tract infection.
In the case highlighted, a 59-year-old woman consumed several litres of water based on medical advice she recalled from previous similar episodes to “flush out her system”. She became progressively shaky, muddled, vomited several times and had significant speech difficulties.

I usually quote the very sad story of the woman who suffered severe brain damage after following advice to drinks large quantities.
Also, well worth pointing out, the amount is meant to include coffee, tea, soft drinks, even soup!
