Summary

The irrigation audit identified a number of opportunities on site including modifying pipe systems to reduce pressure loss, impellor modifications and installation of variable speed drives. Energy savings of 16% with a payback of 1.3 years were identified. The audit also identified up to $11,000 available by reviewing the tariff pricing structure for the pumps. Emission savings have been estimated to be 52 t CO2-e.

Farmer feedback
The total estimated capital cost to implement the recommendations has been an impediment to proceeding. The farm owner is sourcing quotes to assess the cost of staging the upgrade works. While the overall capital outlay was a barrier, the farmer acknowledged the business case was sound and that improvements needed to be implemented.
