I've read that 1/2 your body weight in ounces of water is what is recommended. I'd be drinking about 67 oz. of water, which is perfectly fine. So, you'd need about 65 oz. of water which would only be about 2 L. That might be the confusion, not the number of actual kg or lbs, but oz.
Goals for 2014:
