2009 – The Argentinean experiment

Argentina Business Venture

In a proactive attempt to look for new markets as the Millennium drought really put the squeeze on Australian agriculture, Padman Stops went global!


John and Shawn teamed up with John Schofield to setup a plant in the small regional village of Bahía Blanca, Argentina. While their soils were very porous, they benefited from fast watering from the four different molds we sent over in a shipping container, that was then converted into a concrete curing oven.


Over three memorable trips with lots of fantastic hospitality (they know how to BBQ) and great memories (lost luggage was an interesting one), we continued to supply them with materials and set them up for a thriving business.


As 2010 rolled around we became very busy back home as the drought broke and the eventuation of the on-farm efficiency program, so we left them to it. We suspect the River Diniro irrigation district would have a lot of Padman Stops in it by now!

2008 – Award Winning Innovation

Save Water Award 2008

National savewater! awards® Winner: Regional & Rural category

Judge’s Comments:

Padman Stops have been able to increase the efficiency of flood irrigation without increased energy use.


They have shown potential to make significant future improvements in the industry by means of on farm efficiency as well as environmental improvements as a flow on effect.

2008 – Cotton Industry Solutions

While the company continued to innovate and supply the Dairy, Rice  & Cropping industries for Victoria and southern NSW, the millennium drought proved a challenge for everyone. During this period, Padman Stops began research and development on irrigators needs further away across the nation and found potential within the cotton industry.

Like many R & D projects before and since, we made a big effort to understand what the farmers needed and set about using our experience to develop products that would improve their farms profitability.

Our products have been well received and we look forward to continuing to innovate to find more efficient ways to conserve water and operational costs for the industry.

2007 – Shawn rejoins the company

As Shawn was in primary school when the company started, he grew up taking an interest and working within the business through his teens and early twenties.


Like many, Shawn traveled the world and put many of these skills to use in a variety of industries and returned home in his late twenties to help as the millennium drought really tested the industry, not to mention the company.

2004 – Fast Watering

Fast Water Trials

Definition of fast watering in 2004:
Surface Irrigation applied faster
than 10 ML/day per HA


In 2004, Padman Stops began their “Fast Watering” project, with the aim of creating a high efficiency irrigation system. The theory behind the system was that irrigating faster than the water can soak below the root zone would result in higher effeciency.


John Padman, with this in mind, built a pump with a flow meter that could be used in a trial to measure the effect of “Fast Watering”. Trials conducted have found that the faster the water, the less water is used.


In one trial the application rate of the pump was found to be down to 0.3 mega-litres (30mm application) of water per hectare compared to 0.77 mega-litres (77mm application) per hectare for conventional irrigation.


In recent times, the irrigation industry has been overwhelmed by drought and water restrictions. The aim of the “Fast Watering” project is to reverse this trend.


The findings from three farms that were monitored during the irrigation season between August 2007-2008 are that “Fast Watering” has resulted in water savings of 180.92 mega-litres.


This is the equivalent of approximately 72 Olympic sized swimming pools*.


Water Saving Advantages:
• Additional water can be used to grow more feed or sell.
• Reduced water logging, and soil degradation.
• Increased plant growth, and reduce weed growth.
• Minimize leaching of nutrients.
• Low energy, green irrigation is more carbon efficient.


Keys that control infiltration rate:
• Watering speed
• Soil Condition
• Plant Density
• Soil Type
• Length of Bay
• Slope of Bay


*Calculation based on FINA approved Olympic sized swimming pool of 2.5ML

2002 – MaxiFlow Culvert

John Installing Early MaxiFlow

As the Padman Stops brand and our flat stops and pipe ends became more popular, we were often asked if we made pipes. With some well established companies making quality pipes that suited our product, we were happy to supply their pipes with our products.

After talking to customers, installers and drivers about some of their pain points with round pipe John went into his shed again and began the design process for the MaxiFlow.

The MaxiFlow is a flat bottomed structure with a high strength arched opening that can be extended with multiple units to make custom width crossings. The ease of transport and installation, minimal silting and high flows have given farmers an alternative to round pipes.

They have become so popular we have setup a new company solely focused on a variation of this product that can cater to different applications across exciting new industries.

2021 will be the year for Padman Quick Culverts! 😉

1998 – Supplying for Goulburn Murray Water projects

Gouburn Murray Water - Water Supply project: Channel Overshot doors

John supplied a dozen Overshot style doors to the Goulburn Murray Water supply scheme, who found them to be an excellent solution for some of their Channel stop applications.

These structures were fitted with a custom automation system supplied by Ken Messner of kMed automation, our specialist electronics contractor of 20 years.

GMW have remained a great client over the decades requesting a range of products for their projects.

1995 – Overshot Door

John with Early OverShot Door Install

It wasn’t long until the demand for deeper doors  brought about the ‘B’, ‘C’ & ‘D’ series for the Bay Outlet application.


With water delivery systems requiring even deeper doors, the demand was there for us to create the Overshot, which was the deepest door available at the time and capable of being used as a Channel Stop.


Being 100% watertight and easily transported due to the removable upstream and downstream anti-erosion wings, the Overshot remains a core product to this day.
