If you don't have drains you will create a dry area around the sump pump.
The water under your floor would rather go to the dry area then up through
your floor. Its ability to do that will vary with your soil. Drains make
it much easier for the water to get to the sump pump.

By bringing the water up on to the basement floor or by collecting
water that is already on the basement floor?
