I discovered a nasty case of dry rot in the sill that rides on my
foundation. Luckily, it looks like I caught it just in time, the
floor joists are still level and the sill isn't totally shot.

So, I thoroughly wet it down with a garden hose until I have most of
the dry rot washed away. However, I don't really know how to keep it
from coming back, other than by wetting it down every day, which I am
loath to do.

So, how do I keep everything from drying out and rotting again? Can
I install some sort of drip system like gardeners use? What do most
people use to keep their basements damp enough to prevent dry rot?

Thanks in advance for any answers.

Keeping it wet will not help. You need to cut out the rotted portion
and replace it with new, pressure-treated wood.
