    Explain?  In situations where a vapor barrier was used, it was under the concrete floor before they poured the floor.  The purpose of the barrier was to stop RADON gas from seeping through the concrete over the many years the house will stand there and collect inside the house in the basement. Radon is cancer causing...and is prevalent in certain regions.  Not all houses build before that house had the plastic underlay because it was not known at the time as testing equipment was not used to seek out this gas.  So thousands of houses do not have this as it came in with the updated rules to construction.

    As for collecting water, chances are better that the water will evaporate first then penetrate concrete flooring.
