"carrying along more than a liter or two of water is just plain realistic." Well if you say so!
Also, I hike a ton, many miles up many mountains. 3 liters really isn't that much weight at all, many camelbak style products support that volume, and will get you through a pretty long and arduous day. In my experience 12-15 miles in hot climates.
