Oh absolutely. As with all other infrastructure, there is a cost to be paid. However, when you look at an average to small river, even routing 10 % of the water via an osmosis plant before passing it to the sea is an absolutely massive volume. There’s also the point that you don’t want to build these things in large, meandering, flat river deltas. You want a large salinity gradient, which means relatively small, fast-running fresh water meeting the ocean more “suddenly” than what you get in a classical river delta is the optimal source here.
Gotta be careful about ecosystems though. River deltas are incredibly important and fragile areas.
