Outdoor basement drain - deteriorated drain line

Just purchased home. We are having a problem with flooding in the basement. An interior waterproofing system was installed before purchase. It appears the flooding is coming from under the door. We had a plumber inspect the outdoor drain and was told the pipe was full of rock and debris - basically the pipe is deteriorated (1970's home). He suggested installing a sump pump outside. Is this the best option or should we re-run the underground pipe? Will the sump pump freeze in the winter? What happens during power outages? Looking for the best long term solution. Thanks.

I would repair/replace the drainage pipe. Gravity is always more reliable than a pump.

Depending on how the homes in the area were built it is entirely possible there was never a sewer line from the drain but only a "drywell" to absorb the water. If there is any way to divert the water so it doesn't fill the stairwell that should be explored first.
