Abstract: A reel device for winding/unwinding a continuous dripper irrigation line thereby customizably deploying the dripper irrigation line over an irrigated area and providing irrigation to the area is disclosed. The device includes: a structural frame-work, a rotational pivot suspended by the structural framework, at least one reel sub-unit revolving around the pivot, and a swivel conduit connector having at least one outlet, whereto the dripper irrigation line is connected. The reel device as well as irrigation systems in which such devices can be implemented are equivalently applicable for gardening, farming, industrial agriculture cultivation and crop growing, and for growth of any vegetation type or plant for any purpose whatsoever that reacquire an irrigation.
