Water's tighter on a lot of properties this year than it's been in a while. Dam levels are down in several catchments, some districts opened the new water year with reduced allocations, and plenty of farms have responded the same way: leaning harder on bores and groundwater to make up the difference.
That shift changes more than just where your water comes from. It changes how much is riding on the equipment that moves it, and that's worth thinking through properly rather than assuming this season looks like the last one.
Where things actually stand
A few figures worth knowing:
- Rainfall over the last three years has sat in the driest 10% on record for large parts of southwest WA and southeastern SA farming country
- Several NSW dams were sitting well below a quarter full earlier this year, with one at its lowest level in almost two decades
- NSW opened its new water year with rural storages at around half capacity, and while high-priority users got a full allocation, general security licence holders in some inland districts started with little or none
It's not the same story everywhere. Some regions are fine. But where it's tight, groundwater has quietly become the thing a lot of properties are counting on, whether that's for irrigation, stock, or both.
Irrigation pumps, sized for the season you're actually in
If a bore or river pump used to run occasionally and now it's running most of the time, that's a different job to what it was built for. A pump that starts fine on an easy load can still struggle if the generator behind it wasn't sized for the surge, and that surge matters more with pumps than almost anything else on a property, since motors draw far more getting started than they do once they're running.
Worth checking:
- Whether the generator's rated for the pump's starting load, not just its running load
- Whether the pump is now running longer hours than the setup was ever designed for
- Whether fuel supply keeps up if the unit's running most of the day instead of a couple of hours here and there
Livestock water isn't optional, and it doesn't wait
A cold room warming up during an outage is a problem you can usually recover from. Stock without water isn't the same kind of problem. If your property's water for troughs or sheds runs through a pump, that pump failing isn't an inconvenience, it's an animal welfare issue, and in a dry year there's less water sitting around in dams and puddles to buy you time while you sort it out.
This is the part worth being honest about: a backup generator for stock water isn't really optional in a season like this one. It's closer to essential infrastructure than a nice-to-have.
The dairy shed doesn't get a quiet season either
Milking sheds and cold chains run on a schedule that doesn't bend for a bad water year or a power outage. A vat of milk doesn't care why the power's out, it just needs the cold chain to hold. If your dairy operation's already stretched thin managing water, a power gap on top of that is the kind of thing that turns a difficult season into a genuinely costly one.
Remote and unattended properties carry the most risk
A lot of properties don't have someone standing at the pump when it fails. If nobody's there to notice a generator's stopped running, an automatic transfer switch is the difference between a brief gap and a multi-day one nobody caught in time. That's worth checking now, not after a dry paddock or a dead trough tells you something went wrong days ago.
What's worth doing before the season gets harder
None of this means every farm needs new equipment. A lot of setups can handle more than they've been asked to. But this is a season where the old assumptions about how much your pumps and generators are actually working are worth checking rather than carrying over, given how many properties are leaning on groundwater more than they were a couple of years back.
A few honest questions worth asking about your own setup:
- Is the generator sized for what the pump's actually doing now, not what it was doing two years ago
- Is there a backup for the backup, if the property's relying on one pump for water it didn't used to rely on so heavily
- Would anyone actually know if it failed overnight
