* BELOW IS AN OVERVIEW OF THE ELIGIBLE GRUNDFOS PUMPS:
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:
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 [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].
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.

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.

Following on from the successful construction and commissioning of the Coppabella Water Treatment Plant Aurizon Holdings Limited engaged Dowdens Pumping & Water Treatment [Mackay & Brisbane Branches] to deliver a much needed Sewage Treatment Plant (STP) Upgrade 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 Coppabella STP Upgrade project entailed the addition of an Ultra-Filtration (UF) 'Polishing' Plant onto the existing STP. Dowdens new UF 'Polishing' Plant can produce up to 180 kL/day of treated Class A effluent.
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 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, the recently completed Dowdens whole-of-town Water Treatment Plant and of course the upgraded Sewage Treatment Plant which is now capable of producing 180kL of treated Class A effluent per day for above ground irrigation applications. The local Coppabella Golf Course is one area where this treated effluent is used for irrigation.
After successfully completing various projects for Aurizon Holdings Limited, Dowdens won the tender to provide the process design together with equipment supply, civil construction, installation, commissioning and training for the STP plant operators. The construction phase of the project began with extensive civil works being undertaken to raise the ground level for the new STP components. The pre-existing STP has historically been subject to flooding during heavy rainfall events due to the sites proximity to the local creek. Upon surveying the sites substrate a water table was discovered 1m below ground level.
Working with local Civil Engineers Cardno a substantial foundation was designed / laid to ensure the new buildings, plant components and 4,000 tonne water tank would be stable and remain above the flood plain even during heavy rainfall. Once foundations were laid Dowdens began construction of the 400,000L lined stainless steel water tank, new building to properly house the STP process equipment, an operators office, laboratory facilities and a back-up generator used to power the entire STP in the event of power loss.
After extensive effluent testing and thorough examination of the existing STP process a UF 'Polishing' Plant was designed by Dowdens inhouse Water Treatment Engineering Dept. capable of processing up to 180kL of partially treated sewage effluent per day. The partially treated sewage effluent was rated as Class C and needed to be treated to an acceptable level (Class A) to then be used for above ground irrigation. This treatment process consists of three stages of filtration and sterilisation, including UF. This three-stage process runs as follows:
When the treated effluent arrives in the 400kL stainless steel tank a recirculation system pumps it through a chlorine analyser and back to the treated effluent tank. The chlorine analyser then controls the residual free chlorine level in the treated water and will start / stop a chemical dosing pump as required to maintain the pre-set residual free chlorine level.
Each of the GMF, UF and ACF processes are periodically backwashed and cleaned, with residual waste being fed to a nearby buffer dam where chlorine is allowed to dissipate. Based on the level in the buffer dam and the level in the treated effluent tank, the water may then be returned to the pump station at the front of the STP for reprocessing.
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 client's specific unique requirements. The Coppabella STP Upgrade project is yet another example of Dowdens unparallelled capability to deliver specialised long-term engineered fluid handling solutions from project inception through to final commissioning / handover.
Longreach Regional Council recently engaged Dowdens Pumping & Water Treatment's Mackay & Rockhampton branches to manufacture and install a specialised pool water treatment system for the Yaraka Community Pool in Yaraka (a small town in Central West Queensland located 220 kilometres south of Longreach).
This project began with Longreach Regional Council asking for tender submissions to fully upgrade the Yaraka's Pool onsite filtration & treatment systems. Dowdens Pumping & Water Treatment was successful in winning the tender thanks to our price competitiveness, delivery times and unique in-house fabrication capabilities. On hearing about the tender a representative from the Dowdens Rockhampton branch immediately attended the pool to properly assess and quote the job. It quickly became apparent that a specialised filtration system was needed due in part to the pools remote location (limiting the possibility of regular system servicing), and the extreme weather patterns (high temperatures, dust storms & limited / sporadic rainfall) experienced in Central QLD.
Dowdens then set about designing the new filtration system utilising inhouse Engineering, Workshop Fabrication & Mobile Pool Servicing Departments. The end result was a unique twin-filtration systems that was mounted onto a fabricated galvanised skid to aid in maneuverability, ease of installation & transportation. The skid base was fabricated specifically to fit the existing shed onsite.
Having all the system components plumbed up on a single sturdy base made installation easy as only the Pump Inlet, Pool Water Return and Wastewater Pipes needed to be connected and the system was ready to go. The skid comprised 2x Pool Glass Media Filters, 2x Pool Pumps and 2x Salt Water Chlorinators. The Salt Water Chlorinators are fully automated allowing for round the clock (controlled via sensors) pH and chlorine / acid dosing together with chlorine generation. This has drastically reduced the need for regular onsite water testing and manual chemical dosing at the community pool. On Dowdens recommendation Longreach Regional Council also purchased a Dolphin Robotic Pool Cleaner which has noticeably improved the pools cleanliness.
All design, manufacture, delivery and installation / commissioning was successfully completed by Dowdens well within Longreach Regional Council's delivery deadline of six weeks.
The Yaraka Community Pool is now clean and ready for summer. The new equipment Dowdens supplied has reduced the need for costly regular maintenance whilst improving the automation of the pools chlorine levels - keeping the pool sanitised and chemically balanced at all times is extremely important for any community pool. Dowdens Pumping & Water Treatment's design philosophy for this project was simple: Cost Effectiveness - Ease of Installation - Simple & Effective System Operation - System Reliability & Delivering Greatly Reduced Ongoing Maintenance Requirements.

Anglo American have engaged Dowdens Pumping & Water Treatment's [Mackay] Engineering Department & Fabrication Workshop to rectify an issue with a new valve station installation that was experiencing water hammer, resulting in the longwall mining operation being suspended at their Grasstree Coal Mine, located at Middlemount in the centre of the Bowen Basin, QLD.
Underground mines require water management systems in place to manage working water that is utilised for production, dust suppression, hydraulic jacks etc. Mines employ various methods of underground water transportation systems including Longwall Boost Pump Stations & filtered water from the mine surface networks. The filtered water system is an important piece of infrastructure for underground coal mine providing clean water for dust suppression & feeding the powerful hydraulic piston pumps that are used to jack up the roof in the longwall mining process.
When water is fed into an underground mine it is received at a very high pressures due to the vertical drop to the mine workings. This pressure needs to be reduced & controlled to levels that can be safely managed in the underground operations. Dowdens Pumping & Water Treatment has provided Grasstree Coal Mine with several Pressure Reducing Valve Stations over the life of the mine, enabling reliable & trouble free operation.
Responding to the urgent help request from Grasstree Mine, Dowdens immediately travelled to site to undertake system 'fault finding' & begin planning the delivery of a timely & cost effective solution to the problem.
As a direct result of Dowdens Pumping & Water Treatment's long standing & responsive working relationship with Anglo American's Grasstree underground coal mine, the Dowdens Engineering Department was called on to assist with a new valve station installation that was experiencing water hammer resulting in the longwall mining operation being suspended. Dowdens Engineers attended the mine site & listened/observed the problems that were being experienced such as pressure surges & water hammer in the feed pipes leading to the longwall operation.
Dowdens Engineering Dept. designed & developed a Pressure Setting Spool sized specifically to meet the specific duty required. The spool was custom designed using engineered fluid mechanics to reduce the pressure before it entered the valve station, taking part of the load off the station. Pipe supports were also engineered to provide a secure installation of the station.
The timeline to find the solution & manufacture the components was very tight. Engineering - Concept Design - Drawings & In-House Fabrication of the unique Pressure Setting Spool Piece [with roof bolt anchoring points] were completed & delivered to Grasstree Mine within 5 days from the first site meeting! No other pumping / manufacturing / engineering firm in Queensland was able to deliver such an all-encompassing product solution in the above mentioned time-frame.
Dowdens design philosophy for this project was: Fast Turnaround - Cost Effectiveness - Ease of Installation - Simple Plant Operation - Plant Reliability & Reduced Maintenance.
The unique system required at Grasstree Coal Mine needed to address the following issues:
