When I was on chemo, I was told it was very important to drink ALOT of water (flushes out the toxins in the body, which protects the kidneys!). One liter, I believe, is about the equivalent of two bottles of say, Poland Spring water. I don't think that's near enough. I drank 2 bottles of Gatorade every day, along with eating watermelon, which I craved anyway, Ensure nutritional drinks, ice pops, ice cream. Please try to get him to drink, drink and drink some more.
