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's Rockhampton branch were engaged by local beef cattle graziers Lance and Colleen Sypher (located in Alpha, QLD) to deliver a unique surface mounted Solar Array and Pump Float to supply onsite dam water to both their residence and the property's many cattle watering troughs.
Lance and Colleen Sypher approached Dowdens Rockhampton seeking a design for a solar pumping system with the ability to float on their dam, eliminating the need for any power cables or pump modules to be placed on the bank as is the case with traditional dam solar pumping systems. Having the unit completely isolated (floating) on the surface of the dam would remove the potential for the pumping unit sustaining damage from cattle walking along the edge of the dam. Cattle are known to cause damage to solar pump modules (in particular the associated power cables) that are situated on the edge of dams.
The innovative solar pumping unit design that Dowdens developed needed to meet a required flow rate (during the summer months on average the pumps required duty is 25,000 L/day @ 10m total head). Part of this new design incorporated the solar arrays being installed level with the dams surface, the main advantage of this design feature means the pumps power supply is not affected if the floating pontoon swings or floats across the dam. Having the solar arrays set at an angle, as is found on most traditional solar pumping units, would mean the pontoon would need be to be anchored to the floor of the dam (to avoid any rotation away from direct sun), thereby substantially increasing the overall cost of this project. Angled arrays would have also increased the potential for the arrays to catch any high winds, potentially flipping the unit over into the dam.
Dowdens Pumping & Water Treatment's Rockhampton branch specialises in the design, manufacture and installation of innovative customised Solar Pumping systems for the commercial, agriculture and mining sectors of Central Queensland and the greater Capricorn Coast regions.
The final design incorporated a Mono Pumps 600 Watt SUN-RAY SRX Solar Pump due to it's highly efficient, self-priming helical rotor pump. The pontoon has been designed in a way that it can accommodate a wide range of solar pumping units, making it customisable for whatever site requirements are presented. Dowdens believe this is the first time any pump shop has mounted both the solar arrays and pump unit on a float for this application. Having the solar pump operating independently saves the customer spending time and money travelling to and from the dam each day to switch on the pump.
The entire solar pump float system was designed, manufactured, installed and commissioned 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 - System Reliability & Reduced Ongoing Maintenance.
Dowdens Pumping Rockhampton's Unique Solar Pump Float - Key Components:
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.
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!

Aurizon Holdings Limited have engaged Dowdens Pumping & Water Treatment [Mackay & Brisbane Branches] to deliver a Water Treatment Plant (WTP) at their Coppabella Township, located on the Goonyella Rail Corridor (the world's largest metallurgical coal rail system) - 159 kilometres South West of Mackay, QLD.
The township of Coppabella was primarily designed and built to service the junction of two railway lines (one from Goonyella Coal Mine and one from Saraji Coal Mine) and to provide accommodation to the regions coal mine workers in work depots. The town was established in three stages, with the first being completed in 1971, the second in 1977 and the third and final stage in 1984. The town is wholly owned and operated by Aurizon Holdings Limited and contains: stations, residences, single-quarters, work depots, hotel, a shop, swimming pool, football oval, caravan park, school, ambulance, fire brigade and of course the new Dowdens Water Treatment Plant which is capable of producing of up to 900kL of potable water per day.
Dowdens engineers and service crews designed, manufactured, installed and commissioned the Coppabella WTP to treat raw water to Australian Drinking Water Standards. As the Principal Contractor Dowdens were provided a set of feed supply water parameters coming into the WTP, and water quality requirements for the delivery of the town's drinking water. From these basics the $2.5 million project came to fruition. The Dowdens WTP replaced the existing water softening plant (located adjacent to the new WTP), whilst future-proofing the growth of the Coppabella township by increasing the WTP's maximum daily drinking water production capacity up to 900 kL/day.
The new WTP is completely automated and user adjustable via the GE Human Machine Interface (HMI) situated in the purpose built site Control Room / Office, minimising the need for direct operator interaction / intervention on-site. A dedicated remote monitoring / alert messaging system was also provided so that in the event of a critical alarm the EDAC 700 RTU will call the WTP Operators advising them of system alarm status via pre-recorded spoken messages.
Security of the WTP site was significantly improved with the establishment of a controlled compound restricting access to authorised personnel only (pictured below). Dowdens also eliminated the need for repetitive manual handling of typical WTP chemical consumables on-site (Salt, Liquid Chlorine and Soda Ash) via the integration of various bulk storage systems.
Dowdens were successful in the tendering process due to:
Dowdens coordinated the design, build and commissioning of the WTP from project inception through to final handover. This included, but was not limited to: preliminary design - detailed design - risk assessments (with client and consulting engineers) - preliminary civil works establishing the site (levelling site) - under boring Peak Downs Hwy for installation of raw water pipeline - installation of all underground services - pouring of slabs - construction of the Ion Exchange (IX) building - installation of process equipment - installation of all interconnecting pipework - electrical installation of control panel and field instrumentation / equipment - commissioning of instruments / equipment - commissioning of PLC program and HMI - successful completion of 'Proof of Performance' testing and all necessary operator training.
The inclusion of a unique Brine generation system was a novel approach that incorporated a salt bulk bag unloader (capable of lifting 1200kg bags - pictured below) and a proprietary piece of equipment from the USA [BRINE ExtremePro]. The IX system is flexible in its design and is capable of producing between 150 - 900 kL/day of potable water with the IX system constantly analysing and compensating for variations of incoming bore water hardness levels.
The existing water softening plant (located adjacent to the new WTP) and raw water supply needed to be retained during the new WTP construction. The old plant was decommissioned over a period of 3 months. Nearing project completion a wet weather event (February 2016) resulted in additional water flows through the WTP site causing some minor displacement / erosion of soil and stone that required a brief plant shutdown to rectify the damage. Dowdens performed this work efficiently and effectively eliminating any risk to the township's drinking water supply.
Dowdens Pumping & Water Treatment design philosophy for this project was: Cost Effectiveness - Current Best Practice - Ease of Installation - Simple & Effective Plant Operation - Plant 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.
Key Project Features:
Dowdens Pumping & Water Treatment [Mackay] have delivered yet another Soft Hose Travelling Irrigator to a local Sarina Sugarcane Farmer.
Harvey Matsen [pictured below] operates a 100ha sugarcane farm in Sarina. Due to the lack of rainfall during the 2014/15 growing season he decided to purchase a TRAILCO T-450-2 Soft Hose Travelling Irrigator to better manage the irrigation of his cane.
Wanting to purchase his new irrigator from a local business Harvey sought the services of the Dowdens Mackay Agricultural Sales Team - one of the most experienced Ag sales teams in Australia, with over 125 years of combined irrigation system design and operational experience between them. As a company that has built its foundation on the servicing and development of agricultural pumping systems, Dowdens Pumping & Water Treatment have the experience to engineer a solution to suit any agricultural application. For over 40 years Dowdens Pumping & Water Treatment have been selling & servicing irrigation products throughout Central & Northern Queensland - designing each and every system to improve farming efficiencies, reduce downtime and increase the longevity of pumps / irrigators.
Jeff Roberts from the Dowdens Mackay Agricultural Sales Team visited Harvey's farm on a number of occasions to investigate, design and then match an irrigator and irrigation plan to best suit the property. Taking into consideration the terrain, existing pump capabilities and source water availability Jeff suggested Harvey purchase a TRAILCO T-450-2 Soft Hose Travelling Irrigator with irrigation gun.
Harvey has access to pressurised irrigation water from the nearby Kinchant Dam. Located in Sarina near Kinchant Dam, meaning this farm has access to irrigation water coming via the Eton Water Supply Scheme. Kinchant Dam, situated near Mt Kinchant, 6kms southeast of Mirani, is the only major storage in the Eton Water Supply Scheme. It was constructed to capture runoff water from the small portion of the catchment of Sandy Creek and water pumped from the Pioneer River. Three water harvesting pump stations are located at Mirani Weir below the confluence of Cattle Creek and the Pioneer River, and divert water into an 8km diversion channel into Kinchant Dam. At farm door the dam feed water arrives at between 20 - 30psi. With the TRAILCO T-450-2 Soft Hose Travelling Irrigator needing a higher pressure to operate efficiently Dowdens utilised the farm's existing Power-Take-Off (PTO) Tractor driven booster pump, raising the feed water to over 70psi.
The T-450-2 is able to apply 50mm of water onto a 2ha area of cane whilst travelling along 300m of 4" soft hose - delivering 22.5L/sec @ 70psi. Together with flood irrigation (using the gravity fed Kinchant Dam feed water), an existing travelling irrigator and the new T-450-2 Harvey can now irrigate his property in half the time. In times of low rainfall when young cane is most vulnerable to dry soil conditions, Harvey can now irrigate his young cane faster ensuring they take root quicker and go on to deliver a better overall yield. The T-450-2 is an extremely efficient and reliable soft hose travelling irrigator - so much so it can easily pull Harvey's tractor towards it as it travels down the feed hose on an irrigating run [pictured below].
Dowdens Pumping & Water Treatment [Mackay] have delivered yet another High Profile Soft Hose Boom Irrigator to a local Ilbilbie Sugarcane Farmer. Longtime Dowdens customer Brian Stevens operates a number of sugarcane farms in and around Ilbilbie, QLD. Due to lack of rainfall during the 2014/15 growing season, and a desire to lower his overall irrigation costs Brian decided to purchase a RAINSPAN SB2000 High Profile Soft Hose Boom Irrigator to better facilitate the irrigation of his cane.
Wanting to purchase his new irrigator from a dependable Queensland business Brian contacted the Dowdens Mackay Agricultural Sales Team - one of the most experienced Ag sales teams in Australia, with over 125 years of combined irrigation system design and operational experience between them. As a company that has built its foundation on the servicing and development of agricultural pumping systems, Dowdens Pumping & Water Treatment have the experience to engineer a solution to suit any agricultural application.
Jeff Roberts from the Dowdens Mackay Agricultural Sales Team visited Brian's farm on a number of occasions to investigate, design and then match an irrigator and irrigation plan to best suit the 121ha property. Taking into consideration the terrain, the farms location (near the coastline - a high wind region), existing pump capabilities and source water availability shortages Jeff suggested Brian purchase a RAINSPAN SB2000 93m High Profile Soft Hose Boom Irrigator.
Sugarcane farmer Brian Stevens had for some time wanted to shift away from high pressure irrigation at his Ilbilbie farm, this was due in part to the high coastal winds the property endures year round playing havoc with his irrigation sprinklers. High pressure irrigation was no longer viable for this particular farm as it equated to water was being blown off crop, Brian's associated pumps working hard to deliver high pressure source water to existing soft hose irrigators and excessive mains power being consumed to run said pumps.
Moving from high pressure sprinklers to a low pressure RAINSPAN SB 2000 Dowdens has been able to deliver Brian considerable savings with his overall irrigation costs. The RAINSPAN SB2000 only requires approximately half the pressure to run compared to the previous high pressure irrigators. This has seen between a 30% - 40% decrease in farm irrigation electricity costs.
The low pressure RAINSPAN SB2000 Boom is far less susceptible to high winds, meaning Brian now has the potential to irrigate day or night, regardless of wind conditions. Essentially doubling his irrigation potential each day (the previous high-pressure system needed to be shut down during high winds experienced each night).
The RAINSPAN SB2000 Boom was found to be between 15% - 25% more efficient with its water application uniformity and distribution compared to the previous high pressure sprinkler irrigators. Simply put, Brian can now irrigate his sugarcane in a more cost-effective manner, utilising the limited water available to him more efficiently.
The RAINSPAN SB2000 is an extremely efficient and reliable low pressure irrigator that when installed and operated correctly saves farmers water, energy, time and money whilst increasing overall farm yields.
Key RAINSPAN SB2000 Boom Irrigator features listed below:
