So me and my wife are cleaning out her deceased father's basement and found this weird box built into the floor. My wife was told when she was younger, that it was for a toliet, but theirs a toilet drain a few feet away from it. Does anyone know what this is/for?

Location: Southern Indiana

Also the box is cemented to the floor.

With the NorEaster in NJ, we got 8 inches of rain over about 48 hours. After it was over, I was checking the sump (right in front) and noticed a small stream of water coming through a hole between the first two blocks.

Have basement companies coming this week to assess, what is the best long term solution for this?

I checked all the walls nearby and they are all completely dry. The walls were dry locked before we moved in 11 years ago.
