At the lower end of the Namoi River, irrigator James Moore has transformed a debris-prone, labour-intensive pump site into a streamlined, high-performing irrigation system.
By installing a self-cleaning intake screen, James has achieved consistent flow rates, reduced fuel consumption, and virtually eliminated daily maintenance—delivering measurable operational savings across his mixed cotton and cropping enterprise.
The Challenge
James’ original pump intake was frequently blocked by debris, resulting in reduced flow and ongoing maintenance demands.
“When we were pumping, we’d lose flow every day. You’d start off moving a certain number of megalitres, and by the end of the shift, you’d be down 15% just because of build-up.”
The reduced output impacted more than just the pump. Lower flows disrupted irrigation scheduling, increased water transfer losses, extended field shift times, and drove up fuel usage as operators attempted to compensate for declining performance.
Routine debris removal required lifting pumps for cleaning and repairs—adding downtime and expense during critical irrigation periods.
The Solution
A self-cleaning intake screen was installed to provide continuous debris exclusion while maintaining required design flows.
The automated brush system cleans the screen multiple times per day, preventing build-up and ensuring uninterrupted pump performance without manual intervention.
“The screen cleans itself twice a day, and I only have to check it once a year.”
The Outcome
Consistent Flow Performance
The system now maintains stable flow rates throughout pumping shifts, supporting more accurate irrigation planning and improved water delivery efficiency.
Reduced Fuel Consumption
With pumps operating at optimal efficiency, fuel usage has reduced by approximately 5%—a significant saving across long operating hours.
“We’ve got good, consistent flow now. And because of that, we’re using less fuel to do the same job.”
Minimal Maintenance
Daily debris clearing has been eliminated, and pump lifting for cleaning is no longer required.
“The two biggest benefits are reduced maintenance and improved efficiency. Once the screen was installed, that daily checking and fixing pretty much disappeared.”
Improved Operational Confidence
Initial concerns about maintaining flow rates were quickly resolved once the system was operational.
“It’s exceeded expectations. The flow is consistent, the gear stays clean, and the system basically runs itself.”
Long-Term Value
After a full irrigation season with the new system in place, James considers the upgrade a clear operational improvement.
“It’s not even comparable to what we had before. The old system was low-tech and high-hassle. This is the opposite: simple, clean, and cost-effective.”
For irrigators experiencing debris-related flow losses, increased fuel costs, or excessive maintenance, self-cleaning intake screening offers a practical, long-term solution that improves efficiency while reducing operational risk.
