One, if the choice with water is between pumping and in-situ use, you always pick the latter option. Second..if you do have to pick the former option..pumping saltwater is about the most costly thing imaginable..when it comes to pumping water. Maintenance. Better to pump freshwater in, mix salt in a tank, then discharge and do it again......but there are huge costs (and a bevy of laws) about that as well.
Pumping salt water is about the most costly thing imaginable?
Not really, we've been pumping sea water for years using stainless steel pumps and piping, oil tanker ballast and desalination plants are two that spring to mind.
Ok, for the scenario as described even if the pump/pipework needs to be replaced once a year it's still a lot cheaper than what MS propose.
It's amazing 'science' always seems to 'find' whatever it is funded for, and never the oppsite. Drich.
