What goes up must come down

ADL chose a simple gravity fed stock-water system for the 1500 Acre Milbourne sheep & beef farm in the Hawkes’ Bay.

The main challenge in the Milbourne project was to get the right amount of water to the right places, even though there were varying elevations on the farm.

Water was drawn from an underground spring and pumped some 2800 meters horizontally and 125m vertically to a reservoir on top of a hill, then gravity fed throughout the farm. The high elevation of the reservoir meant the water needed to be pumped at 255 psi and high pressure pipes were needed. ADL and Milbourne chose to have the pipes made to order so that they could achieve just the right thickness and construction for the project.

The result was a system with relatively low capital and running costs and an efficient way to get water throughout the farm. “We’ve now converted an average farm to an intensive operation,” says installer Garry Beckett. “Before this system lack of water meant the farm couldn’t utilize it’s feedstock during dry spell. Now it’s a lot more productive. It was challenging pumping water so high but we got the results we set out to achieve.”

Garry used to design and install water systems but now uses ADL for design services. “Now I can concentrate on installation and making the system work, which I enjoy a lot more than the design.”
