We moved into our house in Draper June of 2011 after a winter with huge snow falls.
The finished basement started taking on water the day we moved in. Not a happy camper.
Our solution was to knock a hole in the floor and put in a large 2" sewage/sump pump in a 36" deep sump.
I calculated from the dimensions that every time the pump ran it would pump out 32 gallons and that spring, the pump would come on every 45 sec.
I've since added a second 12v backup pump and deep cycle battery.
A couple years back, they redid the drainage in conjunction with the new Draper High School and the pump hasn't run a single time since.
Bottom line, if there is positive pressure from water outside the structure, it will find a way in. Removing the water is the best solution.
edit: I had a local plumber put the pump in, core drill the foundation wall and curb, and run the drain line to dump into the street for 2K$
