Beaudesert

Beaudesert Turf Energy

The irrigation energy audit recommended adding variable speed drives to two dam pumps as they have varying duties in supplying centre pivot irrigators. The audit also recommended upgrading 100mm steel main pipe for transfer pumping to 125mm plastic. These initiatives would result in energy savings of over $41,000 per year and a payback period of around 1.5 years.
