Segment Reporting [Abstract]

Schedule of Segment Reporting Information, by Segment [Table Text Block]

The Company’s segments are strategic business units that are managed separately because, while all segments derive their revenues from desalination-related activities, each segment sells different products and/or services, serves customers with distinctly different needs and generates different gross profit margins.
