I recently bought a Drinkwell fountain and unless there is another way the fountain empties itself, it seems Nano is drinking 20 oz of water on a daily basis. I start off with a full fountain and then add a full 16.9 bottle of filtered water each day (full bottle = 16.9 oz, 500 mL) and sometimes more just to keep up. In addition, I still catch her periodically drinking out of the bathroom faucet. She might easily be drinking 25 oz of water every day for all I know.
Granted she is a 14-15 lb cat, but this is approaching how much water a small to medium sized dog might drink on a daily basis!
On the plus side, all the typical tests (scruff neck, etc.) show her to be well-hydrated and she seems to have no pain/trouble urinating it back out. On the negative side, if 20 oz/day actually is a lot of water, it might suggest her kidneys are really shot and she is in serious trouble. But to even things out, she has been with me for six months and has always been interested in drinking water so it hasn't gotten worse -- it is just that she used to drink fro the faucet and the new fountain has actually let me measure what she is drinking.
So how much water do your cats drink and what is considered normal?
