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

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.

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.

Dowdens Pumping & Water Treatment [Mackay] have delivered a Height Adjustable Hard Hose Boom Irrigator to a local Victoria Plains, QLD Sugarcane Farm. Farmer Ian Stevenson operates a number of sugarcane farms in and around Victoria Plains, QLD. Due to lack of rainfall during the 2015/16 growing season, and a desire to lower his overall irrigation costs Ian decided to purchase a MONSOON 125mm x 540m Hard Hose Irrigator, combined with a RAPTOR 47/55 Folding Boom to better facilitate irrigation of his cane.
Wanting to purchase his new irrigator from a dependable Australian business Ian contacted Monsoon Irrigators, who in turn engaged 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.
Brett Hayes from the Dowdens Mackay Agricultural Sales Team had several phone conversations with Ian to begin the investigation and design process for the most appropriate system. Brett then met with Ian in the Dowdens Mackay branch to present the irrigator and irrigation plan that was best suited to Ian's 800 acre property parcel under cane. Ian's experience over many years of irrigation on his property helped both parties recognise the MONSOON Irrigator Dowdens proposed was a perfect match.
Taking into consideration the terrain, the farms location (near the coastline - a high wind region), existing pump capabilities and source water availability (30psi gravity fed via the Eton Water Supply Scheme) and with Dowdens being Authorised Monsoon Irrigator Distributors Brett suggested the MONSOON 125mm x 540m Hard Hose Irrigator & RAPTOR 47/55 Folding Boom.
The Stevenson's farm is located in Victoria Plains near Kinchant Dam, meaning their mains water comes 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.
As this storage dam is predominately used for the irrigation of sugar cane, water from Kinchant Dam is reticulated through open channels and pipelines to the customers by gravity and relift pumping systems. The channel supply system distributes water from Kinchant Dam through 35kms of open earth channels to the various sections of the scheme including gravity fed channels supplying water to Victoria Plains farmers to the east.
30psi inlet pressure and 20psi pressure at the boom (with an average flow of 12L/sec), meant that when Dowdens Mackay Agricultural Sales Team were designing Stevenson Farming's new low pressure irrigation system they did not need to include an electric or diesel booster pump set. This resulted in drastically reduced operating costs for Stevenson Farming as the irrigator can be operated by one man, 24/7 without the need to supply power or fuel to any booster pumps.
The MONSOON Hard Hose Irrigator & RAPTOR Folding Boom is an extremely efficient and reliable low pressure irrigation system that when installed and operated correctly saves farmers water, energy, time and money - whilst increasing overall farm crop yields. Operating off a low pressure gravity fed line of 20psi (at the boom) meant the MONSOON 125mm x 540m Hard Hose Irrigator combined with a RAPTOR 47/55 Folding Boom was perfectly suited for this Victoria Plains farm.
Key MONSOON Hard Hose Irrigator & RAPTOR Folding Boom features listed below:
