__NOTOC__

The dhone consists of a trough made from a wooden log or iron sheet; closed at one end and open at the other. The trough is mounted on a suspended pivoted lever to produce a see-sawing gutter or dhone which operates at relatively low lifts of up to 1.5 m.

Instead of using a treetrunk, a dhone may be made of several planks of wood which can be assembled in the field with bolts. Galvanized iron sheets can also be used. Very large dhones should not be used as the discharge is reduced with increasing dhone volume (presumably because some of the input watts are wasted in manipulating the larger/heavier device (plus water) and so the time per cycle is disproportionately increased).
