Where does the water in a drywell go?

To prevent this, downspouts and drains redirect rainfall and runoff from non-absorbent surfaces (like a roof and driveway) into a concrete galley or dry well that has been buried underground. The perforated unit(s) allow water to dissipate slowly and drain out of the holes, into the ground.

Do dry wells freeze in winter?

A dry well is a large hole placed below the frost line where water can collect and have enough time to dissipate into the ground before freezing.
