What do you mean by "soak away"?

================

I'm not the original poster, but I believe that he is referring
to a system in which a lawn drainage system terminates
in one or more dry wells. The water is, in theory, drained
from problems areas, routed to dry wells, and hopefully it
"soaks away" underground far from the original problem
area.

For any sort of serious drainage problem, especially in heavy
clay, this is generally an unsuitable approach. Instead, drain
"to daylight" and get the water as far away as possible.
