Probably 7 since that's neutral. You wouldn't want to be drinking something acidic or basic... would you? And if it's higher or lower than 7 I wouldn't want to know.

City water supplies are chlorinated to kill any bacteria that might be present. This creates a slightly acidic water which would quickly rust steel mains pipes, so authorities add some lime to adjust the pH to about 7.2. (The pH of your blood is usually between 7.2 and 7.4).
