ROD McKINNON

We wanted to build the new feed pad, and the existing infrastructure that we had just was never going to be satisfactory to do what we wanted. So we actually decided we’d build a large storage pond. The benefits of having storage to me became apparent straight away. So we made it as large as possible, and it gave us the ability to have storage for a good 100 days of the year and then use the nutrients when the farm really needed it rather than spreading effluent when it didn’t need to happen. We have a bunker that separates the solids out, and then the liquid effluent goes into the pond and then we irrigate to probably almost half of our farm. And then we try to use that at times of the year when we’ve got soil moisture deficits, so through the summer or when we want to put effluent onto cropping ground and things like that.
