I have a similar issue, where the water that is seeping in from the foundation walls (under the sprayfoam insulation) pools in one end where there is a small drywell. The drywell fills up if we get too much water too fast. And if it gets to a certain amount, it starts to flow toward the actual sump pump pit...great. But.... it's pitched a little sideways too, so some water flows right past it, and collects around my boiler. The boiler is safely up on 4" of blocking, so that's fine, but its difficult to remove that water once it is laying over there.

Also, when I try to squeegee the water from the overflown drywell over TO the sump pit, it spreads too far left and right, getting under the Oil tank and generally going other places I don't want it to.
So, I decided to get creative with concrete. I did not want to cut into the floor, as I feel it might introduce more potential issues. Instead, I imagined putting some strategically placed small 1" or less tall speedbumps formed from concrete that form mini-dams funneling the water as I squeegee directly to the hole. Several of these can be placed radially like spokes of a wheel toward the sump pit. Also, I think I may put one around the boiler about a foot away to just keep everything away from there.
I think this is a pretty solid idea...I plan to paint them bright yellow or orange like speedbumps so I can see them easily and no one trips. Haven't laid them down yet, because I have just been tinkering with various methods of forming it to the size that I want. I think I've come up with a pretty good forming tool that I made from a plastic bottle with a fairly large mouth (little larger than a Gatorade mouth.) I think it might have been a baby bottle? Comes out pretty professional looking.
