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.

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!
Anglo American's Australian Coal division engaged Dowdens Pumping & Water Treatment [Mackay] to deliver 8 specialised underground pumping PODs used for various dewatering applications at their Grosvenor Coal Mine, located 190km southwest of Mackay in Moranbah, Central Queensland.
The Grosvenor mine is a developing underground longwall operation that makes up part of Anglo American's plan to triple hard coking coal production at their Moranbah mine sites. Located next to their existing Moranbah North coal mine, Grosvenor is set to produce up to 5 million tonnes of hard coking coal per annum for export. The Grosvenor mine utilises a 10km overland conveyor to transport high-quality metallurgical coal to the Moranbah North Coal Handling & Preparation Plant.
Construction on Anglo American's $1.95 billion Grosvenor longwall project began back in January 2013, with the development celebrating a number of industry firsts including being the first underground coal mine in Queensland to use a tunnel boring machine to develop the drifts, or access tunnels, in coal mine development. Anglo American aimed to have the Grosvenor mine raise the bar for onsite system and production efficiency - making the supply of unique underground POD pumping systems a perfect match for Dowdens Pumping & Water Treatment's experienced Engineering Department.
Dowdens Engineering Department's comprehensive abilities have been on the radar of many Central Queensland/Bowen Basin mines for some time through direct contact and working with industry leading consulting engineering firms. Dowdens ability to expertly design/manufacture/install and commission unique equipment built to specific client needs, together with a history of successful installations over the past 15 years in the Bowen Basin has positioned the business as Queensland's premier pumping & water treatment organisation.
Underground Pumping PODs are used in mines as part of the site water management process. Mine water is collected from sumps and wet areas by Wilden air operated diaphragm pumps and delivered to PODs where water level sensors then activate the pump and transfer the collected mine water to a mains pump station, underground storage dam or directly out of the mine portal. Mine water is typically dirty with coal fine, rocks and dirt; therefore slurry pumps are needed to handle such water. PODs can be located in hazardous areas and can be fitted with Flame proof motors and motor controllers with PLC (Programmable Logic Controllers) and SCADA (Supervisory Control and Data Acquisition).
The Grosvenor mine site requirements meant each POD needed to have a 200kW power rating. With the site's physical constraints (i.e. the underground mined roof height and width, as well as the site lifting equipment for transporting) meant careful consideration was required for the overhung load whilst transporting this equipment. Capacity of a standard Dowdens POD is 4m3 with a 110kW motor, however with the larger flow rate required to and from the POD meant a 6m3 capacity working volume was needed. Bigger capacity and higher duty equated to a larger size motor and pump, more robust steel framework and additional accessibility for scheduled servicing.
Dowdens standard POD design incorporates a dirty water receiving area. This area, integral to the main hopper (container for collection of bulk material such as rock or soil), ensures particles that are too large for the pump to digest and transport are separated and manually removed periodically ensuring trouble free pumping.
Pumps selected by Dowdens for this harsh duty were Stalker 400SHD model with mechanical seals, seal lubrication and cooling. Motors selected were WEG brand Flameproof mine spec motors. The control for the pumps is a flameproof 200kW model with PLC and HMI (Human Machine Interface) screens. The controller starts and stops the pump, whilst also monitoring for faults and relaying important information to the mine surface via SCADA. Dowdens PODs built for the Grosvenor mine have the ability of easily interchanging the motors/pumps for differing duties. These will be identified as 200kW and 132kW cassettes. To accommodate this change the Main Control Unit (MCU) has the capacity to operate at either 200kW or 132kW with only slight changes to load controls.
The larger size and the flexibility to change the duty, together with Dowdens strategic POD site placement advice has enabled Anglo American less manoeuvring of the POD through development, saving costly underground labour and downtime. Without reliable pumping the mine's production slows/halts causing delays and safety issues which cost the mine many thousands of dollars each day. It was imperative the system worked and was extremely reliable. This project was delivered on time and within budget. Key project system components are listed below:
Unique features specific to the 8x Underground Dewatering Grosvenor PODs included:
Key Project Features:
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'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.

Here are two videos taken from the latest series of 'Irrigation Efficiency' Case Studies produced by the Dowdens Pumping & Water Treatment Agriculture Department.
The first video illustrates the remarkable energy and water use savings that have resulted from a Valley Polyline Pivot installation at Tony Bugeja's local Mackay Sugar Cane Farm located in Homebush, QLD.
The second video illustrates the considerable energy and water use savings that have resulted from a Variable Speed Drive Irrisys irrigation system working in conjunction with a Valley Centre Pivot and Davey pump on John Fox's 300ha Sugar Cane Farm located in Wagoora, QLD.
Dowdens Pumping and Water Treatment have successfully designed, manufactured and commissioned a self-contained Solar Emergency Eye Wash and Safety Shower. The safety station incorporates both safety shower and eye wash facilities, which are supplied from a water tank via a solar powered Grundfos pump.
This unit was designed and manufactured to comply with Australian Standards AS4775-2007.
Dowdens supplied the portable Solar Eye Wash and Safety Shower station to Downer EDI Mining Blasting Services for use at the Rio Tinto Coal Mount Thorley open cut coal mines (located 15km South West of Singleton in the Hunter Valley region of NSW).
Project's Supply Scope:
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.

Dowdens Pumping & Water Treatment's Proserpine branch provide a range of products and services to island resorts throughout the Whitsundays and Northern Queensland; supplying and servicing everything from pool pumps to major sewage treatment / pumping stations and irrigation systems. We pride ourselves on being able to provide a large range of products across all facets of resort infrastructure.
Dowdens Pumping & Water Treatment's Proserpine branch regularly service customers across local off shore resorts, as well as working extensively with mainland tourist attractions and resorts for both sales and servicing. With extensive knowledge and experience in this area we are confident that our team of experts can provide solutions to clients problems. Dowdens Pumping carries a large range of spare parts and our service team are proud to provide comprehensive and professional after-sales service.
Recently Dowdens Proserpine were engaged by Fullshare Holdings (owner / operators of the Sheraton Grand Mirage Resort Port Douglas) to upgrade 5 existing onsite pump stations that had reached the end of their service life. At the projects inception Dowdens Proserpine conducted a thorough audit of the onsite pumping systems - the subsequent detailed report submitted to Fullshare Holdings resulted in Dowdens being awarded the contract to replace the ageing sewage pump stations. Dowdens Proserpine then set about designing a more efficient and reliable sewerage pump system that was to include smaller and more energy efficient Grundfos pumps, resulting in a reduction in the required maintenance and considerably lower overall energy use onsite. Dowdens Pumping & Water Treatment are Authorised Grundfos Dealers throughout the Whitsundays / Mackay / Rockhampton regions.
"Fullshare (owners of Sheraton Grand Mirage Resort & Mirage Country Club) recently engaged Dowdens Pumping & Water Treatment's Proserpine branch to carry out an on-site audit & submit a report on the condition & performance of our 30 year old sewage pump stations. This audit & subsequent detailed report was thorough & included recommended actions, therefore allowing Fullshare to be fully informed on the condition & improvements required to improve the condition & performance of these important components of our asset. Following a Tender process, we engaged Dowdens Pumping & Water Treatment to carry out the recommended upgrade works to the sewage pump stations.
The challenges of the project were met well by Dowdens Pumping & Water Treatment under the management & extensive office / site based efforts of Kevin Krog (Dowdens Proserpine branch) & his industrial workshop team. Such challenges faced were a fully operational Resort & Country Club, difficult access to some stations, 30 year old supporting infrastructure & services including power supplies as well as contending with it being the wettest & most humid time of the tropical year. Kevin was also excellent at assisting us to liase with the Douglas Shire Council for these works. We will continue to utilise Dowdens Pumping & Water Treatment's expertise & personnel at this property when the need arises & would thoroughly recommend them for these types of works."
Once the design was accepted Dowdens began works that would see 10 new Grundfos sewerage pumps being installed in 5 existing pump stations. The projects scope included supplying and fitting all rails, brackets, lifting chains, concrete pump station lids and non-return valves. Together with the design and installation of Grundfos electronic control panels (Grundfos CU362 Waste Water Controllers) & remote monitoring systems (Grundfos Remote Management [GRM]) which allows for SMS & Email to be sent to relevant site operators alerting them to any faults. The GRM system also allows for system alarms to be reset and pump duties to be modified remotely via any smart-phone or PC. Full product and system descriptions can be viewed below.
The aim of this project was to provide a modern and efficient sewerage pumping system that was energy efficient, reliable, had improved remote monitoring capability and increased level of safety for Dowdens Servicing and onsite technicians. The Dowdens Infield Service Crew began by removing the existing 30-year-old pumps, rails, brackets, lifting chains, heavy concrete lids and control panels. These were replaced with more efficient and reliable Grundfos pumping and monitoring equipment. During installation and commissioning Dowdens had to schedule works to meet the resorts strict operation requirements, ensuring the project proceeded with little to no impact on the resort guests.
The existing concrete lids were damaged and unsafe and needed to be replaced. Dowdens provided 'light lift' aluminium lids with integrated safety grates (pictured below) to minimise the risk of falling into the wet well whilst servicing the pumps. 3 out of the 5 existing control panels were deemed unsafe by Dowdens Electricians and required replacement with new stainless steel panels incorporating the Grundfos CU362 Pump Controllers and Grundfos Variable Frequency Drives on the 2 main pump stations. Dowdens also provided Sheraton Grand Mirage Resort Port Douglas with scheduled servicing of the Grundfos SEV & SE1 pumps; Grundfos CU362 Waste Water Controllers; Grundfos Remote Management [GRM] Systems; Dowdens custom built aluminium lids with safety grates; Stainless steel pump rails; 800kg rated lifting chains & the Backflow protection on wash down taps. The entire project was delivered on time and within budget.
Dowdens Pumping & Water Treatment design philosophy for this project was: Cost Effectiveness - Current Best Practice - Ease of Installation - Simple & Effective Plant Operation - Pump Station Reliability - Advanced Remote Management Capabilities - Reduced Ongoing Maintenance.
