What is the best way to prevent water from accumulating in a window well, and how can a sump pump be effectively utilized in this situation?

To prevent water accumulation in a window well, ensure proper drainage by installing a window well cover and ensuring the area is sloped away from the house. A sump pump can be used effectively by installing it at the lowest point in the window well to pump out any excess water that collects, helping to prevent flooding and water damage.
