THC in
urine, if they are looking for drugs, yes, it shows up in a
urine test. A basic urinalysis though, they are probably not checking for drugs and it would not have been tested for. However, that you added water (they aren't dumb, if it were that easy, all who use drugs would do this) and they will surely know--- you've just made them suspicious of you.
