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 Mackay branch was engaged by Anglo American - Moranbah North Coal Mine to design, engineer and build a boost pump station to supply raw water to the longwall area. Dowdens Pumping & Water Treatment designed and built the longwall boost pump station utilising dual variable speed pumps to enable the station to cater for varying duties as the underground workings progress further away from the station.
Anglo American's Moranbah North coal mine began operation in 1998 as an underground longwall mine and currently supplies 4.5m tonne annually of high fluidity premium hard coking coal mainly for export to iron and steel manufacturers in Japan, Korea and Taiwan.
All design, fabrication, installation & commissioning of the longwall boost pump station was undertaken by Dowdens Mackay's in-house Engineering, Fabrication & Workshop Departments and all electrical componentry of the longwall boost pump station was supplied, installed and commissioned by Major Electrical. 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 water management project. We truly are Queensland's premier one-stop-shop for pumping and water treatment systems!
"The longwall booster pump station was taken underground into immediate service after only a couple of days. There is normally a one or two month delay with above ground commissioning for all new units. Since the pump powered up after the first run it has not stopped running and is sitting at only 10% duty. The longwall has cut 128,000 tonnes so far which is exceptional. Any future boost pump orders from Dowdens Pumping & Water Treatment will not require any changes to the design or manufacture saving us both time & money."
The pump station boosts water pressure to the longwall currently some 6,000m away. Comprehensive 'pre-challenge' testing was completed prior to the station being transported to site, with all parameters being set during this time. Dowdens internal teams of specialised engineers, CAD draftsmen and tradespeople were able to design and build the station on time and to a tight budget, with Anglo American extremely happy with the work undertaken and product supplied.

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.
Arabon Seafoods employed Dowdens Pumping & Water Treatment [Mackay] to deliver a broad acre irrigation system watering their cattle feed pasture located in Bowen, QLD. Arabon Seafoods are a proud Queensland small business specializing in the sale and export of locally sourced live, chilled and frozen seafood.
Dowdens designed an efficient energy and water use irrigation system for Arabon Seafoods that utilises a Valley Two-Wheel-Linear Irrigator - the ideal irrigator for smallholder growers with limited access to electricity - together with a Nelson S3000 Spinner Sprinkler Package, Nelson 110VAC Shut-Off Valve, Valley Autopilot GPS Ready Control Panel and a Yanmar 10kVa 3-Phase Diesel Generator Set.
The Valley Two-Wheel-Linear Irrigator is a fairly standard machine in it's configuration but it's application to Arabon's cattle feed pasture is a departure from local practice. Most irrigation in this region is normally provided by low pressure boom type irrigators which are far less efficient in regards to energy and water consumption when compared to the Valley machine.
The system is required to pump water directly from onsite bores to the Valley Two-Wheel-Linear Irrigator watering 3.5 ha of cattle feed pasture. The irrigator's purpose is to provide water to a 'baleable' hay crop which is periodically onsold to local graziers as stock feed. The installation of a Valley linear irrigator has greatly reduced the number of irrigation runs that Arabon Seafoods has previously undertaken with their smaller boom type irrigator to water the same area of crop. Valley Two-Wheel-Linears deliver the ability to easily tow or swing the machine around to cover more acres.Valley's 'easy to operate' Valley Autopilot GPS Ready Control Panel has enabled other Arabon Seafoods personnel to operate the irrigator which had always proved difficult in the past using a more dated irrigator. The GPS Ready Valley Autopilot Control Panel allows linears to automatically perform functions similar to a center pivot. The AutoPilot Linear measures the lateral position and direction of travel of the linear, allowing functions to be easily programmed to run automatically.
Dowdens Pumping & Water Treatment [Mackay] are the sole Valley Irrigation Master Dealers for the Mackay / Whitsunday region enabling the best possible pricing and unmatched product support for all of our customers.
Arabon Seafoods contacted Dowdens Mackay in mid-2015 and requested a site visit and quote. Within a week the Dowdens Ag Sales Team were onsite taking measurements and discussing options with the business owners. A system was designed to suit the area and application, and the quote was delivered. Arabon Seafoods was happy with the design and pricing and instructed Dowdens they would budget for this system in 2016.
Fast forward to mid-2016, working closely with the business owners Dowdens had successfully refined the quote and sourced all materials to be supplied. The purchase order arrived with Dowdens in late May 2016 - the irrigator was delivered to site on Friday 24th of June. The installation commenced Monday 27th of June and the machine was fully operational and commissioning was completed by Wednesday 29th of June.
Dowdens Pumping & Water Treatment's design philosophy for this project was: Cost Effectiveness - Current Best Practice - Ease of Installation - Simple & Effective System Operation - System Reliability & Delivering Reduced Ongoing Maintenance Requirements.
The entire project was overseen and managed by Brett Hayes from the Dowdens Pumping & Water Treatment [Mackay] Agricultural Sales Team.

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:

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's Brisbane branch has built a strong relationship with Sullivan Nicolaides Pathology (SNP) after more than 25 years of providing high purity water treatment systems / solutions for 22 of their Commercial Testing Pathology laboratories - from as far north as Cairns, down south to Coffs Harbour and everywhere in between. The majority of Dowdens Pumping & Water Treatment's high purity water treatment systems are used primarily in Sullivan Nicolaides blood testing machines. SNP was formed in 1956 when Dr John Sullivan started a small pathology practice to service local families in and around Brisbane. Dr Nick Nicolaides joined him 18 months later and since then, it has grown to one of the largest and most trusted pathology practices in Australia.The PROBLEM:
Tap or 'town' water contains many substances that if left untreated, can react with the reagents used in controlled laboratory tests, causing positive or negative interference which leads to unreliable test results. Cations such as sodium, calcium, magnesium or iron; anions such as bicarbonate, chloride and sulfate; and other inorganic ions, are commonly found in tap water. A number of other contaminants - such as pyrogens, nucleases, alkaline phosphatase and endotoxins may be present. As they are not harmful for human consumption, they are not thoroughly regulated or tested in the course of South-East Queensland municipalities potable water treatment and distribution. These contaminants are detrimental to experimental / laboratory processes that require precision, high sensitivity and precise instrumental operation.
Water purification is highly dependent upon local (and even site-specific) variations in the make-up of the town / tap water quality, which can differ greatly from place to place. For this reason Dowdens Engineers have designed each and every SNP high purity water treatment system individually, with local and site specific feed water characteristics in mind. The most recent system was installed at SNP's Central Laboratory located in Bowen Hills, QLD.
After careful analysis of the town water being delivered directly to SNP's Bowen Hills Laboratory a turn-key 'looped' treatment system was designed, manufactured and incorporated into SNP's existing Building Maintenance System (BMS). The first stage of this looped system is pre-treatment of the town water via a set of Duplex Carbon Filters and Water Softeners. The water is then fed through Duplex Matten Reverse Osmosis systems and Duplex 10" Deionisers and then stored in four 1,000L loop tanks. This treated water then passes through a set of four Deioniser Polishing Systems which (via a pump) is recirculated into and around the labs as 18 MΩ/cm ultrapure water (UPW).
This 'looped' high purity water treatment system delivers 56,000L of 18 MΩ/cm UPW / day - providing not only the capacity required for SNP's entire Bowen Hills Central Laboratory, but also delivering sufficient redundancy so that during times of service / maintenance the lab and testing machines are never without sufficient UPW to remain operational.
Dowdens Pumping - Brisbane's design philosophy for this project was: Cost Effectiveness - Ease of Installation - Simple & Reliable Plant Operation - System Reliability & Reduction of Ongoing Maintenance Costs. The entire SNP high purity water treatment system was designed, manufactured, installed and commissioned on time and within budget.
