An addendum to the above would be:
If there is sufficient height beneath the suspended slab and if the slab
is an ordinary cast-in-place-on-top -of-re-usable/removable-forms type,
with maybe a concrete beam to shorten the span of the slab...
An idea worth reviving IMO is the "rainwater cistern in the basement" that
was common in many (most ?) of the farmhouses built in the 19th and
early-to-mid 20th C in my old neighbourhood of Oxford/Brant/Waterloo
counties in SW Ontario.
That cistern was the potable water supply for the house to help relieve
some of the load on the groundwater well or in some cases, it was simply a
more palatable alternative to high iron/sulphur content well water.
In some more modern homes where there might be an attached garage, the
cistern would be in the foundation volume beneath the garage floor slab.
In some cases when the cistern was abandoned, a doorway would be punched
through the foundation wall separating the basement and the ex-cistern and
the cistern would be turned into a root cellar.
