modeling of the concentrated seawater discharge's dispersal and dilution to develop a strategy for minimizing its effect on the balanced indigenous community (BIC). This strategy focuses on preventing rather than lessening the potential effects of elevated salinity discharge through "in pipe " dilution of the concentrate before it is released, and the flow of the effluent into receiving waters having a high mixing potential due to the presence of wind- and tidally driven currents. The strategy of optimizing site-specific features to maximize the dispersal and dilution of the discharge is in full agreement with recommendations found in the recent report on desalination by the U.S. National Academy of Sciences (NRC, 2008). It is also consistent with practices for concentrate discharge management currently in use by the 25 mgd desalination plant now operating at Tampa Bay, Florida. For the large capacity plants in Australia, for which the receiving waters do not in all cases have a sufficient mixing capacity to dilute the discharge, or in other cases where salinity equilibration must occur within a limited area, high-velocity diffuser nozzles are placed in series along the discharge line on the seabed to promote the mixing and rapid dilution of the seawate
