It's a wild plant in the UK, and grows not just in water but on the muddy edges of streams.
The idea of growing it in running water is that running water is less likely to have the snails who are the intermediate host.
Using "water from the river" as the OP suggests is, in infection terms, the same as growing it in the river, so what he needs to do is filter his water to bring it up to standards of quality suitable for growing watercress - ie not just filter out the relevant life stage of the fluke, but also any bacterial nasties that are in there.
