How about the drugs?: There is nothing you can add or subtract from diet to pass a drug test, except eliminating the drugs. You don't need all that water, and it will cause a dilute urine which will automatically flunk the drug test. This idea that we need lots of water is bogus; thirst is the best guide. We get all the water we need from our food (60% water), if your urine is dilute you are drinking too much.
