Sump pit with no pump

We have had a lot of rain recently in the Maryland area so I was poking around looking for water infiltration. I took the cover off of the sump pit and saw very little water. I knew that I did not have a sump pump but I do have a question. Why do I have this pit? It has exposed rocks in the bottom and two 4 inch pipes leading into the pit. It looks like very fine particulate is mounded up under both pipes. Is this a silt basin? I have no water problems at all but this thing doesn't make since to me. It is poorly covered and I want seal the cover to keep moisture and radon out of my laundry room. I do have a fairly sloped yard from front to back with a walkout basement. This pit does seem to be in the "low" corner of the house. Can I use this as my main suction point for a radon mitigation system or would I just be sucking air out of the pipes and not from under the slab? Thanks.

Sounds to me as though it's a drywell for a french drain system?

Do you know that you have a radon problem? or just thinking ahead?
