Vonmac has recently exported and installed 6 weirs to Indonesia as a trial project for a large fibre plantation water management system. The Plastipile™ weirs have been installed in tropical peatlands to improve the management of water levels below the peat surface reducing the rate of peat subsidence and peat degradation. This translates to low carbon emissions and improves the productivity and longevity of the fibre plantations
The six weirs with drop-gates, essentially in kit form, were fitted with an assortment of automated systems including moisture probes to log ground water levels, air temperature, the water level of the water ways, weather stations to record local conditions and remotely controlled actuators to open or close the gates. Solar-powered field units were installed to permit remote access via a web based global service. In August, Garry von Bertouch traveled to Indonesia to conduct training of the local staff on how to install the Plastipile™ weirs and use the high tech, customised, equipment. The Plastipile piles were installed to a depth of 4 metres into the peat and fitted with aluminium drop gates.
Vonmac Pty Ltd has completed construction of the Kings Billabong environmental regulator in just 26 days. This included driving 345 Plastipile™ plastic sheet piles into the creek bed, fitting 6 drop-board gates, each 1.8m x 1.9m (a total of 11.4m of gate frame) and finally the installation of a 26.6m aluminum walkway.
A healthy billabong to benefit all
The regulator was built downstream of Lower Murray Water's Central Pump Station across Psyche Channel that flows into Kings Billabong, near Mildura, Victoria, with the aim to benefit both irrigators and the environment. The regulator will be used during times of low demand for irrigation water (the off-season) to manage flows into the wetland. By managing the amount of water entering Kings Billabong, it will be possible to restore a more natural wetting and drying cycle, which will help improve both the water quality and health of the plants and animals that rely on the wetland.
Pioneering methods and a patented product results in fast installation with minimal disturbance
Vonmac's unique construction method ensures minimal construction work was required, apart from the removal of the old concrete levee. The patented, interlocking Plastipile piles are installed using specialised pile drivers and powerful water-jetting equipment, without the need for any heavy equipment that can be detrimental in a fragile ecosystem.
Plastipile was chosen for this project as it was developed in South Australia specifically for use in wetland areas. Plastipile has the ability to be built into a continuous, watertight retaining wall of varying heights, and in this case, incorporating large drop-board gates.
Funding for the Kings Billabong environmental regulator was provided by the Victorian Government and coordinated by Mallee Catchment Management Authority, in partnership with Lower Murray Water and Parks Victoria.

On 24 November 2004 Vonmac was invited to attend the annual SA Great Regional Awards 2004, held at Renmark’s Chaffey Theatre. They were pleased to be presented a certificate ‘Highly Commending’ them in the category of ‘Science & Environment’, for the Riverland/Murraylands Region.

In November 2004 Garry von Bertouch competed on the ABC’s, ‘The New Inventors’ program, (Episode 36). He was up against some tough competition:
• Pumpwatch, by Anthony Kahl, which is an integrated system, providing remote monitoring and control of diesel and electric powered irrigation pumps of any size.
• Breakout Barrier Release System, by Michael Watmough, which is a pneumatic latch mechanism that will automatically or manually unlock security barriers (bars, screens, doors) in an emergency, to prevent people being trapped.
The judges decided that Vonmac’s Plastipile™ was the best new invention of the evening and awarded them the trophy.
