Cecil,
Yes, the water just flows through the raceways, to a large aquaculture greenhouse, through an even larger aquaculture high tunnel, and then through a bio filter bag before going into about a half-acre pond used for growing things like water cress. The water then goes into a creek where it is purer than when it comes out of the spring.
If anybody wants to visit sometime, just let me know and we can arrange such a visit. It is always changing, but here is a little info from about 18 months ago.
