Urge to urinate within an hour of drinking some water?

If I drink even a small amount of water, say, one or two mouthfuls, I usually get the urge to urinate within an hour of drinking it. When I do urinate, the amount is not large and roughly corresponds to the amount I just drank. Sometimes, I get the urge to urinate in much shorter intervals (30 mins or less) usually after I eat.

Is this normal?
