If you mean what looks like a drain at the bottom of the pool and the pool is empty you are probably seeing the hydrostatic valve at work. it is there to allow ground water into the pool in order to stop it from floating in ground water that builds up under the pool when it is not full of water.
to keep drunks from peeing in it....

One way would be to install drain tile in the yard around the pool deck to carry excess ground water away from the pool.
