How Many Well points does it take??

Not a fan of well points. They don't work well in many soils. If you dont have sandy type the water wont flow to them. Best is a sump pit using a 10" PVC standpipe and a large hole around it filled with clean gravel and filter fabric. Depth to the deep point of the pool about even with deep end. If they are trying to dewater to install liner they should just wait for dry weather or put pump inside pool and work quickly it can be done that way

Only 3 of the well points have been pumping significant amounts of water.

There are 3 tied together on one side, and 3 on the other. They stopped using the others.

Pensacola Bay is across the road and there is a drainage pond about 1/2 block away.

Water was coming into the pool at the deep end.

Now, the good part. The pumps in the deep end have been running for about 2 weeks. Yesterday we were told to completely fill the pool and a worker came by to put the drains, skimmer panels, coping and tiles on as it was filling. I wake up this morning and there is place about the size of a football that is caved in at the deep end where the well point is. I’m assuming this is serious? The company isn’t calling me back.

What should I do?

Also, is it possible the pump has been pumping everything in that area out?

If only they would have! Thank you.
 
With that much water, the soil can be weakened and collapse. A lot depends on how much stress the liner is under at the cave in spot. If it's stretched out, it should be repaired quickly.
