You can be sure that this is not the first time that water has leaked in. Consider yourself fortunate that you are finding this out now. Was this defect listed on the Form 17 (IIRC that's what it is called)?
Solution? Either eliminate water source (often difficult if not impossible) but check for downspout discharge locations, yard sloped towards the foundation, and other potential sources for outside water.
Long-term solution is to lower the hydraulic pressure on the other side of the walls. This is typically done by saw-cutting a trench in the floor along the perimeter walls and installing a drainage pipe which leads to a sump in one corner in which a sump pump is located. Trench is filled with drain rock and then cemented over. Pump discharges outside somewhere where the water will not make it back into the house.
If you plan on ever finishing any of the basement spaces, they have these really-cool 1/4" thick "water-collection" panels that are porous on the back and sealed on the opposite side which are permanently attached to the cement walls, with the bottoms of the panels draining into the floor trenches described above. Wall is then covered with moisture barrier and finished conventionally. Any moisture which makes it through the cement wall is collected by this panel and harmlessly drained away.
Of course, any time you are dependent upon an electrically-powered pump to keep your house dry, you have to also think about what happens during a power outage (which tend to occur during the big winter storms). They have battery-powered backup pump systems available (good if you are away from home when the power is out), or you can consider a small generator.
Don't ask me how I know all this stuff! My crawl space turns into an Olympic-sized pool when the power is out for a few hours during a storm. Yes, I did know about this when I bought the place. Yes, I have spare pumps in the shed as well as a generator and fresh gas. Yes, it sucks to own a house with water problems (sewer problems warrant a completely separate post and I'll spare you the details).
Let us know if you are spitting in the ocean, swimming against the current, or just rolling down the river, as this story goes downstream.
