The purpose of this paper is to provide an overview of current desalination technology and a

preliminary assessment of the potential for desalination in developing Pacific Island Countries.

Historical and current methods of desalination are discussed, with an overview of known desalination

plants in the Pacific. Two case studies are described, based on two different desalination technologies

with a baseline financial cost comparison of the two systems along with a preliminary assessment (in

appendix A), of the estimated cost of rehabilitating a typical community rainwater harvesting catchment,

for comparison.
