Maybe he likes water. Call your family docter or take him for a checkup. Good luck

My in laws cat drinks lots because it diabetic, that may be a something to think about

I think you maybe should be concerned cause there is such a thing as water toxic
Where you can drink yourself to death.
He could have an electrolyte imbalance or something so ask the vet.

Farmerjohn is right too it could be a sign of diabetes

At 16 years old, this is a geriatric boy! He definitely needs to see the vet. Increased water consumption can be a sign of kidney problems, diabetes, infections, or other serious problems. Occasionally older dogs have a problem similar to Alzheimer's in people, and their eating/drinking or sleep/wake cycles can change dramatically.
It may turn out to be nothing major, but an ounce of prevention..
