Hose move sprinkler system
is an improvement on the conventional piped hand moved systems and
combines some features of semi-permanent installations with those of
permanent ones.
In this system the
sprinkler lateral lines are placed permanently at a wide spacing 55-60 m
apart. The system consists of a series of small protective housings (pods),
which contain and protect a sprinkler. The sprinklers, mounted on tripod
stands are not fitted directly to the lateral pipes, but connected by low
density polyethylene pipe (PE) 20-25 mm in diameter and up to 30 m in length. The
small, flexible hose can be shifted in only minutes by a four wheeled
motorbike by simply driving across the paddock (see
pictures).
The hoses with the
sprinklers can be moved laterally on either side to cover a number of
lateral positions. The sprinklers are low to medium pressure.
It is a system with low
capital cost, easy installation and easy shifting suitable for all types
of terrain. They are usually used for
pasture irrigation on
undulating/hilly topography.
Capital cost can vary between
2,200-2,800 AUD/ha and the system can provide 50-60% efficiency. |
