The Williams GB Magnum Travelling Raingun Irrigator is a game changer in effluent irrigation!
The Magnum is the first of its kind, featuring a patented design that blends the high performance of a static raingun with the proven reliability of our Greenback travelling irrigator. This innovative combination delivers superior coverage, efficiency, and dependability—outperforming all other effluent irrigation systems on the market.
Until now, the only way effluent could be applied at application rates below 10mm/hour is with the use of static sprinklers or moveable pods. The problem with this is up to 19 shifts are required to cover a paddock 150 x 250 metres. With the Williams GB Magnum, the same sized paddock can be covered evenly with only 2 shifts.
When fitted with a Williams Auto Shut-off valve and/or a GPS system, over application of effluent is practically impossible. With a pod system, if the pods are not shifted before each pump cycle, the pods will continue to irrigate the same areas until they are moved.
Why spend tens of thousands of dollars on an expensive solid separation system creating more labour requirements when you can irrigate your effluent in a single nutrient rich state. Because the GB Magnum is utilising nozzles with diameters greater than 13mm, A Williams inline filter is the only form of filtration your system will require. This is particularly important if irrigating straight from a sump scenario.
