r1 vs r2

suppose you drink some water. part goes out thru the urinary system. the urethra. i call that route1 or r1. part goes out thru the rectum. it becomes part of the fecal bolus. that is r2. i want to know if the ratio r1/r2 depends on what you drink. i live in the tropics where i can get coconut water. would that be just as good as water for bringing more liquid to the bowel to help clean the bowel.
