Around 20% of homes in America have their own septic tank. And essentially all of them flush their toilet paper like everyone else.
They did put sewers in about 15 years after the houses were built, and mandated hooking into it on the next septic tank pumping. But the tanks are left underground, as removing them would leave a 20 foot hole in the backyard of each house.
In short, what's this about tossing your stool in the trash?
What? Where/when/why is that necessary?

After moving back to the USA it was just as weird to put paper in the toilets (though drinking the same water you bathe in was the weirdest part).
I think people exaggerate the weirdness and difficulty of adjustment, because in both instances it took me a week at most to get used to either way.
Surely you mean the water that enters the house via plumbing, is used for both bathing and drinking from via a faucet. As opposed to drinking bath water.
Is the weirdness of that because they don't drink tap water in the Dominican?
Yes, almost nowhere in Central America would you (or locals) drink water from the tap. Things like brushing your teeth are a grey area.
