If the rest of the basement isn't even sloped towards this drain, why
do you need to keep it accessible?

Does it (or will it ever) serve any purpose at all?

Apparently I can swim in it and/or wash my dog.

From a local building code perspective, it has to be accessible. It
will also be convenient for the annual 'drain-the-water-tank'
maintenance, but generally it will be unused.

I think the answer in this case will be to pour new concrete to fill
the area in, then use it as if it was a normal floor (with an access
hatch cut for the drain).
