Drinking a bunch of water in the days or weeks before a U/A is of no help. Unlike other types of drugs, THC is not water-soluble. THC is fat-soluble. THC is stored in the fat cells and remain stored until the fat cells are burned for energy. Therefore, you cannot "flush" or otherwise rid the fat cells of THC by drinking copius amounts of water.
When fat cells burn, the THC metabolites are released back into the bloodstream. The kidneys filter the THCA from the bloodstream and are deposited into the bladder for the eventual exit. The rate of filteration is unaffected by copius water consumption.

Drinking water is only helpful on the day of the U/A. Thats because the water consumption serves to dilute the THCA concentration that is present in the bladder. The dilution pnenomena, however, is only temporary - once the fluids ingested had all been urinated out, the bladder is replenished with fresh THCA-laden urine by the kidneys, and thus the donor is right back to square one.

You should pick up a home THC test kit and test yourself to see where you stand. When testing yourself, be sure to use the first-mornings urination. If you test positive, then you should consider looking towards substitution and find a clean urine sample to use for the scheduled U/A. Read up on the Substitution "sticky" thread.
