Cannonvale was amongst the hardest hit regions during Cyclone Debbie, so it was no surprise to Dowdens Pumping & Water Treatment's Proserpine Branch to hear Queensland Health had been advised they couldn't be guaranteed potable water supply to their Whitsunday Community Health Centre located in Cannonvale immediately after Cyclone Debbie.
Luckily Dowdens Pumping & Water Treatment's Head Office in Mackay had a portable Ultrafiltration Treatment System available, capable of supplying up to 70,000 litres of potable water per day. Queensland Health and the Whitsunday Community Health Centre in Cannonvale instructed Dowdens Pumping to supply/install the unit immediately on a temporary 'Hire' agreement in-case all mains water supply was lost.
There were two water sources available at the time - the mains water supply or bore water from the Proserpine Hospital. Queensland Health instructed Dowdens to connect the UF Treatment System to the bore water supply, in an effort to remain as self-sufficient as possible post-Cyclone Debbie.
Dowdens Pumping have previously completed numerous bore water filtration systems treating bore water with our own brand of PURION Iron Removal Filters, so this emergency UF Treatment System was quick and easy to install. PURION Iron Removal Filters pre-treat the bore water before running it through the Ultrafiltration System which then doses the filtrate with liquid chlorine to further disinfect.
Once treated Dowdens Pumping manually transported numerous loads of the potable water from the Proserpine Hospital (where the UF System was installed) directly to the Whitsunday Community Health Centre in Cannonvale, where it was stored in a potable water grade storage tank. The treated water was then used to supply the medical centre. The entire supply/installation and commissioning was successfully completed on Saturday 1st of April - only 4 days after Cyclone Debbie had hit.
If you are ever in need of potable water during a storm or emergency contact Dowdens Pumping & Water Treatment. Dowdens only require access to a reasonable source of water (bore, dam, creek) and power (generator or mains power) and we can guarantee same day potable water supply, in any situation!
Dowdens Pumping & Water Treatment have successfully designed, installed and commissioned a specialised Ultraviolet filtration system for the Queensland Health Mackay Renal Unit.
Project Requirements: The original system operated by pumping town water to individual filtering stations where the water would pass through a 5 micron, 1 micron and carbon filter on its way to the dialysis machine (which has an internal reverse osmosis filter).
The issue Dowdens faced was the original system filters were only lasting between 5 - 15 hours, and by this stage they were black and needed to be replaced!
After reviewing detailed water test results, Dowdens designed a compact, reliable system where the existing pump was upgraded, a water softening unit was added to remove iron, calcium and manganese. Large cartridge filters were also installed to pre-filter the water before it entered a dedicated UV steriliser.
Using the above system the Mackay Renal Unit now only needs to replace the systems filters every 7 to 10 days - saving thousands of dollars in ongoing system maintenance costs!
Grundfos has long been regarded for their high quality and reliable pumps. The Grundfos SCALA2 takes design innovation, comfort and simplicity to the next level and is set to be a game changer in domestic boosting. The NEW Grundfos SCALA2 is a robust, fully integrated, self-priming pump suitable for use from both above and below ground water sources. The compact system features a pump, motor, tank, sensor, drive and non-return valve in one compact unit that is quick and easy to install.
The SCALA2 is an energy efficient pump featuring an integrated speed controller that ensures constant water pressure regardless of variations in demand or inlet pressure. For those living in areas of poor power supply or those that are sometime affected by power outages, the SCALA2 can also be run on a generator, due to its ability to be able to handle varying voltages.
The variable speed controller also matches the power consumption with the required water output, which also helps to conserve energy and reduce your energy bills. To protect the pump and help ensure a long life, the SCALA2 includes a range of protective features. Dry run protection automatically stops operation when the water source runs out, to help prevent damage, and the anti-cycling feature detects any unnatural cycling and alerts the user via the protection indicator on the control panel.
Another unique benefit of the SCALA2 is its quiet operation, thanks to the permanent magnet motor and water cooling technology. The high efficiency motor is significantly quieter than traditional speed-controlled motors and the SCALA2 is cooled by the water it pumps, eliminating the need for a noisy fan. This makes the SCALA2 one of the quietest domestic boosting pumps currently available on the market.
For ease of selection, the SCALA2 suits most domestic pressure boosting applications and is capable of supplying water for small single level homes up to larger multi-storey homes.
Racecourse Projects recently engaged Dowdens Pumping & Water Treatment's Mackay 'Infield Service Crew' to undertake emergency repairs to a damaged Valley Irrigation Centre Pivot Irrigator at their Sugar Cane Farm located in Marwood, QLD.
This project began, like most emergency repair jobs do with an unexpected call from our customer. Racecourse Projects rang the Dowdens Pumping Agricultural Sales Team to inform them a Cane Haul-Out Truck had struck the first span of their Valley Centre Pivot. The pivot was now hanging precariously and needed to be repaired immediately. Daryn Gray (Dowdens - Industrial Workshop [Engineering Support]) and Brett Hayes (Dowdens - Agricultural Sales) promptly attended the Marwood site and assessed the pivot. Dowdens advised the pivot needed to be supported or it may have collapsed further. Straightaway the Dowdens 'Infield Service Crew' were onsite to elevate and secure the damaged span.
After speaking directly with the manufacturer of the damaged Valley Centre Pivot (Valmont Industries - Australia) Dowdens confirmed with Racecourse Projects there were no suitable spans for that machine currently available anywhere in Australia. This meant repairs needed to be undertaken promptly before the machine potentially collapsed completely - making any further repair work impossible. Dowdens then promptly engaged a local subcontractor to work alongside the Dowdens 'Infield Service Crew' repairing the machine in situ (whilst still suspended in the air). As the repairs had to be effected whilst the machine was still standing, this required coordination between 2 cranes and a telehandler forklift, along with a man box (attached to the all terrain telehandler) for 2 men to carry out the repairs. All the repairs and commissioning of the irrigator were successfully completed within 2 days of the accident!

Downer EDI Mining [a division of Downer EDI Limited] has engaged Dowdens Pumping & Water Treatment [Brisbane] to design, manufacture, install and commission a Heavy Vehicle Wash Bay and associated plant treatment equipment at the Meandu Coal Mine located in Tarong, South East Queensland.
Since January 2013 Downer EDI Mining has been providing mining services at Meandu Mine as part of their long-term rolling contract with TEC Coal Pty Ltd, a wholly owned subsidiary of Stanwell Corporation Limited. Downer provides a total mine service to TEC Coal, including mine management, planning, drilling, overburden removal (including dragline and truck-and-shovel operations), coal mining, coal processing, rehabilitation, and maintenance of mobile and fixed plant.
Downer EDI's Heavy Vehicle Wash Bay project tender was won primarily due to Dowdens ability to expertly design / manufacture / install and commission specialised equipment, built in-house & onsite to meet our specific client's unique requirements. With a history of successful installations over the past 15 years within the Queensland Mining Sector, Dowdens is Queensland's premier pumping & water treatment organisation.
Downer's project brief to Dowdens Brisbane was for the design / manufacture / installation and commissioning of a Heavy Vehicle Wash Bay capable of processing a minimum of 5 vehicles per day, with each vehicle taking approximately 1 hour to wash. Meandu Mine required this new Heavy Vehicle Wash Bay to be constructed after the mine had recently purchased a fleet of new generation trucks (KOMATSU 830E Trucks) which are considerably larger in size compared to their existing fleet.
To ensure Meandu Mine continued to meet their Environmental Discharge requirements Dowdens designed and incorporated 4x Settling Pits & 3x Oily Water Separators into the construction of the Heavy Vehicle Wash Bay. In Queensland it is a legal requirement for mine sites to treat (separate) any sludge or oil from any waste water coming from a Heavy Vehicle Wash Bay.
Pictured below you can see the 4x large Settling Pits (empty) that are used to catch / store (via gravity feed) waste water from the Wash Pad area. The waste water generally contains some grease, oil, coal fine and soil (mud). The coal fine, mud and other solid particles washed off the trucks is allowed to settle to the bottom of the Settling Pits - the pits are then intermittently emptied by a Bobcat excavator.
The waste water (still containing grease and oil) is pumped from the Settling Pits via progressive cavity pumps into 3 individual 'Oily Water Separators' to remove the remaining contaminants. Once the waste water has been through this treatment stage it is pumped back into Meandu Mine's network of onsite holding dams to be used in other site extraction and processing applications.
Dowdens design philosophy for this project was: Cost Effectiveness - Current Best Practice - Ease of Installation - Simple Plant Operation - Plant Reliability & Reduced Maintenance.

Arabon Seafoods employed Dowdens Pumping & Water Treatment [Mackay] to deliver a broad acre irrigation system watering their cattle feed pasture located in Bowen, QLD. Arabon Seafoods are a proud Queensland small business specializing in the sale and export of locally sourced live, chilled and frozen seafood.
Dowdens designed an efficient energy and water use irrigation system for Arabon Seafoods that utilises a Valley Two-Wheel-Linear Irrigator - the ideal irrigator for smallholder growers with limited access to electricity - together with a Nelson S3000 Spinner Sprinkler Package, Nelson 110VAC Shut-Off Valve, Valley Autopilot GPS Ready Control Panel and a Yanmar 10kVa 3-Phase Diesel Generator Set.
The Valley Two-Wheel-Linear Irrigator is a fairly standard machine in it's configuration but it's application to Arabon's cattle feed pasture is a departure from local practice. Most irrigation in this region is normally provided by low pressure boom type irrigators which are far less efficient in regards to energy and water consumption when compared to the Valley machine.
The system is required to pump water directly from onsite bores to the Valley Two-Wheel-Linear Irrigator watering 3.5 ha of cattle feed pasture. The irrigator's purpose is to provide water to a 'baleable' hay crop which is periodically onsold to local graziers as stock feed. The installation of a Valley linear irrigator has greatly reduced the number of irrigation runs that Arabon Seafoods has previously undertaken with their smaller boom type irrigator to water the same area of crop. Valley Two-Wheel-Linears deliver the ability to easily tow or swing the machine around to cover more acres.Valley's 'easy to operate' Valley Autopilot GPS Ready Control Panel has enabled other Arabon Seafoods personnel to operate the irrigator which had always proved difficult in the past using a more dated irrigator. The GPS Ready Valley Autopilot Control Panel allows linears to automatically perform functions similar to a center pivot. The AutoPilot Linear measures the lateral position and direction of travel of the linear, allowing functions to be easily programmed to run automatically.
Dowdens Pumping & Water Treatment [Mackay] are the sole Valley Irrigation Master Dealers for the Mackay / Whitsunday region enabling the best possible pricing and unmatched product support for all of our customers.
Arabon Seafoods contacted Dowdens Mackay in mid-2015 and requested a site visit and quote. Within a week the Dowdens Ag Sales Team were onsite taking measurements and discussing options with the business owners. A system was designed to suit the area and application, and the quote was delivered. Arabon Seafoods was happy with the design and pricing and instructed Dowdens they would budget for this system in 2016.
Fast forward to mid-2016, working closely with the business owners Dowdens had successfully refined the quote and sourced all materials to be supplied. The purchase order arrived with Dowdens in late May 2016 - the irrigator was delivered to site on Friday 24th of June. The installation commenced Monday 27th of June and the machine was fully operational and commissioning was completed by Wednesday 29th of June.
Dowdens Pumping & Water Treatment's design philosophy for this project was: Cost Effectiveness - Current Best Practice - Ease of Installation - Simple & Effective System Operation - System Reliability & Delivering Reduced Ongoing Maintenance Requirements.
The entire project was overseen and managed by Brett Hayes from the Dowdens Pumping & Water Treatment [Mackay] Agricultural Sales Team.
Key Project Features:
Dowdens Pumping & Water Treatment's Rockhampton branch working closely with Dowdens Pumping - Mackay's Industrial & Fabrication Workshops have successfully designed, manufactured and commissioned a Customised Dewatering Pump System for YANCOAL Australia. YANCOAL own and operate the YARRABEE Coal Mine & Boonal Joint Venture Coal Load Out Facility that is located 40 kilometres north-east of the township of Blackwater, QLD in Central Queensland's Bowen Basin. The Boonal Joint Venture is a coal load out facility located on the Capricorn Highway in Central Queensland, Australia. Coal from both the Yarrabee Coal Mine and Jellinbah Coal Mine are transported via rail link to the Port of Gladstone from the Boonal coal load out facility.
After initial site visits Dowdens Pumping - Rockhampton were able to measure the height and distance required for the dewatering pump system, as well as clearly establish pipe sizes and required flow rates to adequately meet the clients onsite dewatering requirements. This led to the in-house design of the unit by Dowdens Pumping - Mackay's Engineering Department. Once the proposal had been accepted by the client CAD drawings were immediately created and passed onto the Dowdens Industrial Fabrication Workshop.
Boonal Joint Venture's Customised Dewatering Pump System Supply Scope:
As Dowdens Pumping are an authorised FLOWSERVE Pumps Distributor, we were able to quickly and easily size and source a FLOWSERVE Hydro Titan Pump. The Hydro Titan 100x65-250 Pump has a capable duty of 14 l/sec (@ 50m total head) and perfectly matched the clients site requirements. From here Dowdens Industrial Fabrication Workshop welded the skid base together which was then bunded and fully hot dip galvanised. This innovative system utilised a universal coupling, installed between the pump and motor to reduce the chance of miss alignment occurring between the pump and engine.
Dowdens Industrial Fabrication Workshop then proceeded to assemble and mount the 125l diesel fuel tank, Yanmar 3TNV84TEPP-PE 3-Cylinder Diesel Engine, Hydro Titan 100x65-250 Pump and install the universal coupling. Dowdens Electricians then connected the battery and solar array charger module to the canopy [pictured below], whilst mounting the Yanmar 'Engine Protection Unit'. The engine was then taken outside and tested. Once all this was completed it was transported to site where final commissioning was successfully completed.
The complete Boonal Joint Venture's Customised Dewatering Pump System was designed, installed and commissioned by Dowdens Pumping on time and within budget. Dowdens Pumping & Water Treatment's Rockhampton branches design philosophy for this project was: Cost Effectiveness - Innovation - Ease of Installation - Simple & Effective Pump Operation - Engine Longevity - System Reliability & Reduced Ongoing Maintenance.

Wilmar Sugar Australia Limited employed Dowdens Pumping & Water Treatment [Mackay] to deliver a broad acre irrigation system at their Gibson Creek sugarcane farm. Wilmar Sugar Australia Limited is Australia's largest raw sugar producer and one of the top 10 producers in the world.
The Gibson Creek sugarcane farm has a total area of 2,000ha, with works completed by Dowdens to date delivering irrigation to over 750ha of sugarcane - this project is still ongoing with the aim to irrigate the full 2,000ha upon completion. The broad acre irrigation system was designed, sourced, installed and commissioned by the Dowdens Pumping & Water Treatment Agricultural Sales Team, which has over 125 years combined agriculture irrigation experience.
The system is required to pump water stored in Wilmar's onsite dam (which when completed will hold a total of 2,000ML) to various irrigation devices watering 2,000ha of sugarcane.CLICK IMAGES TO VIEW FULL PROJECT GALLERY
To date the project has seen the team at Dowdens construct, install and commission six Valley Center Pivot Irrigators, with spans ranging from 520m down to 410m, and three hard hose poly line traveling irrigators.
Water for the irrigation system (sourced from Wilmar's 2,000ML onsite dam) required Dowdens to lay an extensive network of poly and PVC mains pipework ranging from 500mm to 150mm in diameter. In total over 12kms of mains pipe has been laid so far.
The entire system is gravity fed from the large onsite dam with a 6-cylinder John Deere diesel engine centrifugal pump feeding the six pivots, and three IVECO-Caprari multistage diesel booster pumps [pictured below] kicking in to raise mains pressure when water is required at the three hard hose poly line travelling irrigators.
The entire project was overseen and managed by Glenn Agnew from the Dowdens Pumping & Water Treatment [Mackay] Agricultural Sales Team.
