Holes in sewage pump basin?

I'm putting a sewage pump basin in my basement for a bathroom, it has a 4" waste inlet.

Upon excavating for the basin i found where our historical water problem in the basement is coming from. Water is entering the soil under the slab when it rains hard and eventually finds its way to above the slab.

What i would like to do is drill 1/4" holes around the side of the basin at a height between the top of the basin and the side inlet. My theory being that it will let the rainwater in but the waste should theoretically never get high enough to escape out through these holes.

bad idea?

horrile idea. you need to install a sump pump completely separate from the ejector pump each in it's own hole. ejector pump should sit in it's own completely sealed basin for odor and health reasons. the sump pump should sit in it's own open bottom basin which is filled with large sized crushed stone so as not to clog the pump and allow water to rise naturally. then the sump pump will pump water to the exterior of the house via a pvc pipe and the ejector pump will pump waste into the sewer system.

That is a excellent reply for a junior member.
