Hmm, I haven't heard of this issue in a male dog before...it's very common in spayed females. This happens to some of them either after the spay or when they're a bit older, muscles lose their tightness from lack of estrogen, not unlike women going through menopause.
I have heard decent things about the belly band for dogs who mark, I would assume this is alright for him, as a temporary solution. I know some folks who use those doggy diapers on their females as well and are pleased with the results. You could put those on for bedtime.
Does the urine smell different than regular urine? How about his breath, does it have a funky tinge to it?
I'd have a full bloodwork panel run, and talk to your vet and see if he or she thinks that something like Proin could work for him. Clearly it's not an estrogen thing, but Proin tightens up urinary muscle in males and females.
Keep us posted, I'm really interested in what this could be.
p.s. The water intake thing makes me wonder too, can you ask the former owners exactly what was going on with his kidney values? As in, ask them to provide bloodwork numbers, vet records, etc.
