Florida Tech's pilot will pump ~0.5 cubic meters per second of ocean water into a small cove in the northern Banana River for one year. Cost: about $4.9M on top of $2.5M in prior research. From Florida Tech's own FAQ: "Enhanced seawater exchange would not, on its own, solve lagoon water quality issues."
To scale that to lagoon-wide impact would require pumps moving 500–1,000× the pilot rate, at 12–15 MW continuous — roughly $12–15M/year in electricity alone, on top of nine-figure capital. All to do what a passive tidal inlet does for free.
Our take
Run the pilot. It will settle a two-decade debate. But nitrogen source reduction — septic-to-sewer, stormwater, muck removal, exactly what SOIRL funds — is doing more measurable work than any pump ever will. Vote Yes on the source-reduction program while the pump science is still being tested.
