An induced symbiotic osmosis pump (ISOP) (and method of using same) comprising: a closed loop comprising a riser pipe and a downpipe having substantially the same length fluidly communicating at a base with an induced osmosis semipermeable membrane and fluidly communicating at an opposed end with a brine pump fluidly communicating with a pressure exchanger fluidly communicating with a reverse osmosis membrane, the downpipe comprising a check valve; the induced osmosis semipermeable membrane of the closed loop fluidly communicating with an initial reverse osmosis module fluidly communicating with a brine pump fluidly communicating with a source of fluid having an initial salinity; the brine pump electronically communicating with an electrical source; and, the reverse osmosis membrane fluidly communicating with a storage tank.
