Dry well to help drain off well water....

[JohnT]

Normally such dry wells are placed in the backfill for the pool, which is where the ground water tends to accumulate. It would probabl depend on your soil type whether one adjacent to the pool like that would help.

I have one under the deep end of the pool and I can valve it in to the main circulating pump and pump it to waste to remove that water than would otherwise get behind the liner.
