Dehumidifier yes. Down the sump, no.

Parts of the midwest, especially in old houses with stacked rock foundations have similar issues, running the collected water to a tank to use for house plants or future filtration and drinking may be a consideration.

Parts of the year, we’d run two dehumidifiers, some years they were hard pressed to keep up. Sometimes they didn’t.
One year I remember 4′ of water, it was a very wet year though.

Some 25 years later, a proper basement has been poured, and most of the moisture issues are gone. Now just the usual 95% humidity and condensation.
