Wesfarmers Resources, a significant Australian producer of metallurgical coal engaged Dowdens Pumping & Water Treatment's Industrial Workshop [Mackay branch] to deliver fast-turnaround servicing to a large selection of DAVEY Water Products Vertical Multistage In-Line Pumps [pictured below] that are used onsite at their Curragh Coal Mine, located 30km north of Blackwater in Central Queensland. This servicing project presented a number of challenges for the Dowdens Mackay Industrial Workshop, none more important than the tight timelines in which these repairs needed to be completed.
These DAVEY Vertical Multistage In-Line Pumps play a crucial role in the operation of the mine as they are used in various dewatering applications and also to boost supply of water to all of Curragh Coal Mine's various processing areas - including the vitally important Coal Handling & Preparation Plant (CHPP). Wesfarmers are supremely confident in having their pumps serviced by Dowdens Pumping, because after many years of working together they know Dowdens always aim to provide the sale / service of suitable pumps that maximise service life and minimise power usage and downtime. Improving levels of equipment utilisation whilst reducing planned / unplanned maintenance downtime increases the overall productivity of a coal mine.
Wesfarmers Curragh Coal Mine is an open-cut coal mine that provides metallurgical coal for export markets and supplies steaming coal to the Queensland Government's Stanwell Corporation under a long-term contract. Stanwell operate two major electricity generation assets, the Stanwell Power Station located in Central Queensland and the Tarong Power Station, located in the South Burnett, Southern Queensland. Wesfarmers Curragh Coal Mine has a well-established and geographically diverse customer portfolio with a number of long-standing relationships with world-leading steel-makers.
Like with any pump that arrives to Dowdens Pumping - Mackay's Industrial or Domestic Workshop, these Davey VM Vertical Multistage In-Line Pumps were serviced using Dowdens established workshop repair procedures. It was these established procedures and highly regarded workmanship that prompted Wesfarmers Resources to award Dowdens this important servicing contract. Dowdens Pumping - Mackay are so confident in our Workshop Servicing Capabilities we offer a "12 MONTH WORKMANSHIP GUARANTEE" for any service completed in-house - this is by-far the best guarantee available in or around Mackay, QLD. All pumps were successfully serviced and returned to site within Wesfarmers specified deadlines, meaning less downtime for Curragh Mine's related water infrastructure.

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.
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.

Long-term customers Michelmore Grazing Company have recently purchased seven solar powered pumping systems from the Dowdens Pumping & Water Treatment Mackay branch. All the solar systems supplied are used to pump water from onsite bores to poly water storage tanks, to then feed the properties multiple cattle water troughs. Some existing bores were used to replace dated diesel setups / windmills, along with some new bores being added to increase the total number of watering points for the cattle. Michelmore Grazing Co. purchased three Solar Pumping Systems for Fort Cooper Station and another four systems installed at Kainga Station.
This 6 month project saw Dowdens Mackay source, supply, install and commission a number of GRUNDFOS & MONO solar pumps, a MONO 2400 WATT Solar System (all used in conjunction with solar panels / frames) and undertake repairs on an existing Mono Diesel Pump system at Michelmore Grazing Co.'s Fort Cooper and neighbouring Kainga Stations (Nebo, QLD). The repairs carried out on the existing Diesel Driven Mono Helical Rotor Bore Pump involved replacing the rusted head housing with this pump now being used as a back-up for one of the new Solar Pumping Systems.
The high-quality GRUNDFOS & MONO Solar Pumping Systems have already delivered Michelmore Grazing Co. notable cost savings via a reduction in diesel fuel usage and a significant decrease in the need for ongoing diesel motor maintenance. Michelmore Grazing Co. now saves both time and money by not having to undertake laborious daily checks on the diesel pump sets fuel levels.

Dowdens Pumping & Water Treatment's Mackay branch were engaged by longstanding customer Anglo American (Moranbah North Coal Mine Site) to deliver an innovative valve system that could help maintain the safe and reliable delivery of general purpose & fire water services to their ever-expanding underground mining operations. With growing demand for reliable water flow & pressures at ever-increasing operating depths, Dowdens decided it was time to design & produce a new generation 35 bar Dual Pressure Control Station, expanding our range of standardised pressure reducing valve stations.
Dowdens Pumping & Water Treatment fabricate and fit out a range of standardised pressure reducing valve stations, but this station required a higher pressure rating not available with our standard 'off the shelf' systems that are available in 16 / 25 bar (35 / 40 bar rated systems are built to order). Dowdens have manufactured these products for many years to help our resource industry customers arrest any water pressure spikes and/or surges in pipe systems and to aid these mines operating within and remaining fully complaint with Queensland Government Mine Site Compliance legislation, standards & guidelines.
This new Dual Pressure Control Station has been built to optimise plant reaction speeds, allow for greater operating ranges from between 2 - 35 bar and is manufactured with high-quality, reliable and readily available components. The design needs for the new Dual Pressure Control Station were borne primarily from Dowdens detailed underground observations of hydraulic occurrences within the mines existing water network. Working closely with the mines water infrastructure operators Dowdens were able to engineer, manufacture and deliver a product that increased the reliability of their mine water supply systems and assist with premeditated preventative maintenance routines.
All design, fabrication, installation & commissioning of the 35 bar Pressure Reducing Valve Station was undertaken by Dowdens Mackay's in-house Engineering, Fabrication & Workshop Departments. With a history of successful installations over the past 20 years throughout the Queensland Mining Sector Dowdens Pumping & Water Treatment have the ability to expertly design / manufacture / install and commission specialised pumping and water treatment solutions that are built primarily in-house & onsite to our client's specific unique requirements. Dowdens dedicated departments of industry trained engineers, draftsmen, project managers, sales staff and tradespeople including fitters, mechanics, polywelders, machinists, plumbers, electricians and boiler makers enable us to offer an unmatched range of world-class engineering solutions for any type of fluid handling project. We truly are Queensland's premier 'one-stop-shop' for pumping and water treatment systems!
At this projects inception Dowdens visited site to examine and document the specific operating requirements. After initial observations it was concluded that a wider operating range would be required for effective control of both the High and Low Flow demands and a higher adjustment range - meaning the standard Dowdens 25 bar Pressure Reducing Valve Station needed to be modified to suit this application. This higher pressure is not normally encountered with Queensland underground mine water supply systems so unique and customised hydraulic control layouts, pilots & hardware were seamlessly incorporated into the build by the Dowdens Mackay Workshop and Project Engineers.
This projects entire design, manufacture, installation & commissioning process was completed on budget and within a tight timeline of 4 weeks set by the customer.
Anglo American (Moranbah North Coal Mine) 35 bar Pressure Reducing Valve Station - Key Components:
Dowdens Pumping & Water Treatment's Rockhampton branch were engaged by the Queensland State Government's Department of Environment and Heritage Protection to deliver an efficient solar pumping system at the disused Mount Chalmers Gold Mine (located 15km North-East of Rockhampton, QLD).
As part of this sites ongoing rehabilitation process the Department of Environment and Heritage Protection needed an efficient solar pumping system to recirculate contaminated mine water collected from a sump, back into the main pit, thereby eliminating any contaminated mine water runoff from site. The Department of Environment and Heritage Protection has been managing the key environmental issues at the Mount Chalmers Gold mine since the former operators Affinis Pty Ltd was placed into liquidation in December 2014. EHP is also supported by other government agencies including the Department of Science, Information Technology and Innovation (DSITI) who are providing scientific advice on technical aspects of site management. The primary ongoing focus is to prevent any discharge of contaminated water from the site.
With limited mains power available to the site the use of solar power was a perfect fit for this pumping application. Solar powered pump solutions are always improving, none more so than Grundfos Solar Water Solutions. During initial site inspections the pumps required operating duty was calculated to be 13L/sec @ 18.5m Total Head. To meet these high flow requirements a Grundfos Solar Inverter (RSI) was selected to power the Grundfos R Series Submersible Pump [SP46-3 5.5kw 415V] that the Department of Environment and Heritage Protection already had onsite. The Grundfos R Series SP46-3 is a Stainless Steel pump capable of handling the low pH, slightly acidic mine water (measuring between 2 & 3 pH) needing to be pumped.
Utilising a combination of Grundfos Solar Water Solution products (inverter / pump / solar panels) appealed to the Department of Environment and Heritage Protection as it meant Dowdens could supply a system that not only costs less to install and maintain, but importantly can pump a larger volume of water under solar power. Put quite simply the ability to run large 415V pumps capable of greater pump duties is making the decision to 'go green' and install solar powered systems more attractive in the current climate, for miners and farmers alike.
Dowdens Pumping - Rockhampton initially visited site to establish location of the solar arrays and calculate pump duty. Once known the following components were sourced and prepared for installation: 36 x 270 Watt Grundfos Solar Modules, 2 x 18 SolarTerrace Module Fixed Array Frames, 7.5 kW Grundfos RSI Inverter & Sine Wave Filter and 200m of 110mm PN10 Poly Pipe. The Grundfos SP46-3 5.5kw Pump was attached to a specialised float that sits on the surface of the sump (pictured below). Pump starts & stops via a level float switch mounted on 4m pole that can be swivelled over to the sump's bank should any maintenance be required.
Local contractors were then engaged to complete the site earthworks and trenching needed for all electrical conduits. Once the solar array support posts were cemented in place, Dowdens Pumping - Rockhampton assembled the SolarTerrace Array Frames and mounted the 36 modules (2 x 18 Modules) ready for the electrical components to be installed.
Electrical contractors RILEC Electrical (accredited electrical/solar contractors) completed the electrical fit-out. As part of these works Dowdens Pumping - Rockhampton delivered the Grundfos Solar Inverter Sinewave Filter & String Connection Box (pictured below) to the RILEC workshop so it could be mounted in a powdered coated, lockable enclosure with sufficient ventilation to ensure the inverter remains cool during the day. RILEC then brought the control box to site, mounted it and completed all wiring to meet electrical standards and the site specifications. All commissioning of this system was undertaken by Dowdens Pumping - Rockhampton.
Dowdens Pumping & Water Treatment's Rockhampton branches design philosophy for this project was: Cost Effectiveness - Innovation - Ease of Installation - Simple & Reliable Pump Operation - System Reliability & Reduced Ongoing Maintenance. The entire Grundfos RSI Solar Pumping System was designed, manufactured, installed and commissioned on time and within budget.
