Cannonvale Medical Centre Water Treatment System post Cyclone Debbie

Wednesday, 19 April 2017

Severe Tropical Cyclone Debbie made landfall near Airlie Beach on the Nth QLD coast 28th March 2017. It was a slow-moving category 4 system that generated wind gusts exceeding 160 km/hr, heavy rainfall and storm surges along the Nth QLD coastline. 27 hours later, after having tracked inland over Airlie Beach, Proserpine, Cannonvale and Collinsville it was downgraded to a Tropical Low. Dowdens Pumping & Water Treatment's Proserpine Branch is again open for business.

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.

PURION - Water Treatment Products by the Dowdens Group

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!

Grundfos RSI Solar Pumping System

Case Study

Customer: Kurrajong Pastoral

Location: Springsure, QLD

Specifications & Features:

Dowdens Pumping & Water Treatment's Rockhampton branch were engaged by local beef cattle graziers Kurrajong Pastoral (located near Springsure, QLD) to deliver a GRUNDFOS RSI Invertor Solar Pumping System at the Crystal Plains property to supplying onsite bore water to the property's many beef cattle watering troughs. Crystal Plains is a 3,018ha (7,458 acre) Springsure buffel grass property located 52km south of Emerald and 22km north of Springsure. The property comprises 10 dams, three bores, 14 grazing paddocks, plus several holding paddocks and water squares.

Dowdens Pumping - Rockhampton began the design of this solar pumping system with a site visit to record the height / depths of bores and to meet with the customers and garner their exact requirements for this system. Although not required for this particular bore inspection, Dowdens can offer our customers affordable Borehole and Drain inspection services using a range of Wireline Cameras. Our Wireline Cameras can operate up to a depth of 100m and deliver our customers high-resolution video and images straight to laptop / USB.

Once the proposal had been accepted, the Dowdens Industrial Workshop began sourcing the 18 x 270 Watt Solar Modules that were to be attached to 3 x 6 Module Fixed Post Array Frames. As an Authorised Grundfos Distributor Dowdens Pumping - Rockhampton were able to confidently recommend a Grundfos RSI Inverter together with the efficient SP7-17 415V Submersible Pump to be mounted and installed on this solar pumping system. The system pumps directly from a bore to an elevated position on Crystal Plains where the customer is then able to gravity feed from their established tank farm to the greater majority of his property. On average the pump transfers 50,000L/day.

"We have been working with Mitch Williams and the team from Dowdens Pumping & Water Treatment's Rockhampton Branch for a number of years and have always been happy with their service and back up support. We highly recommend Dowdens Pumping & Water Treatment's Rockhampton Branch and Mitch Williams for all their help with sourcing what we have needed for efficient stock watering systems & solar pumping applications. But it's not just the products, Dowdens have also installed & commissioned all these pumping systems for us. Cheers."

Dowdens Grundfos RSI Solar Pumping System

Details:

The existing pump that Dowdens replaced was an old line shaft MONO pump that was operated by Diesel engine. The installation of the new Grundfos solar system lowered ongoing maintenance and operation costs considerably as the clients no longer had to replace the column due to the accumulation of rust. To ensure this wouldn't happen again Dowdens utilised stainless steel and poly pipe in the construction.

Operating costs were lowered via the system utilising a Grundfos Invertor with Sine Wave Filter Isolation Switch together with a tank level pressure switch - meaning the pump would start and stop automatically, only when needed. This automatic operation eliminated the need for the client to regularly drive to the bore to start and stop the pump. This increased pumping efficiency also saved on the overall cost of diesel to refuel the pump. The Grundfos Invertor with Sine Wave Filter Isolation Switch, together with the Grundfos SP7-17 415V Submersible Borehole Pump were pre-wired on a custom-fabricated steel mounting frame to enable easy 'plug & play' installation. Dowdens supplied 5km of poly pipe for both the tank fill line and the gravity feed lines.

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. The entire Grundfos RSI Solar Pumping System was designed, manufactured, installed and commissioned on time and within budget.

Game changing GRUNDFOS SCALA2 PUMPS now at Dowdens

Tuesday, 14 March 2017

Dowdens Pumping & Water Treatment are your local pump experts and are Authorised Grundfos MASTER DEALERS. Dowdens are Mackay's ONLY Authorised Grundfos MASTER DEALERS & Dowdens Rockhampton branch is also an Authorised Grundfos MASTER DEALERS. Grundfos pumps are market leaders, committed to providing new and innovative products that take comfort and simplicity to the next level, for these reasons we sell and recommend the new SCALA2 domestic pump.

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.

Customer: Sheraton Grand Mirage Resort Port Douglas

Location: Port Douglas, QLD

Specifications & Features:

Sheraton Mirage Port Douglas Resort

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.

Heavy Vehicle Wash Bay

Case Study

Customer: Downer EDI Mining

Location: Tarong, QLD

Specifications & Features:

Downer EDI Mining Pty Ltd

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.

Dowdens Pumping & Water Treatment - Meandu Coal Mine Heavy Vehicle Wash Bay [Tarong, QLD]

Details:

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.

Community Pool Filtration System

Case Study

Customer: Longreach Regional Council

Location: Yaraka, QLD

Specifications & Features:

Yaraka Community Pool - Dowdens Pumping & Water Treatment Pool Filtration System InstallationLongreach 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.

Yaraka Community Pool - Dowdens Pumping & Water Treatment Pool Filtration System Installation

Details:

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.

RAINSPAN High Profile Boom Irrigator

Case Study

Customer: FS Stevens and Co.

Location: Ilbilbie, QLD

Specifications & Features:

RAINSPAN High Profile Soft Hose Boom Irrigator

Dowdens Pumping & Water Treatment [Mackay] have delivered yet another High Profile Soft Hose Boom Irrigator to a local Ilbilbie Sugarcane Farmer. Longtime Dowdens customer Brian Stevens operates a number of sugarcane farms in and around Ilbilbie, QLD. Due to lack of rainfall during the 2014/15 growing season, and a desire to lower his overall irrigation costs Brian decided to purchase a RAINSPAN SB2000 High Profile Soft Hose Boom Irrigator to better facilitate the irrigation of his cane.

Wanting to purchase his new irrigator from a dependable Queensland business Brian contacted 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.

Jeff Roberts from the Dowdens Mackay Agricultural Sales Team visited Brian's farm on a number of occasions to investigate, design and then match an irrigator and irrigation plan to best suit the 121ha property. Taking into consideration the terrain, the farms location (near the coastline - a high wind region), existing pump capabilities and source water availability shortages Jeff suggested Brian purchase a RAINSPAN SB2000 93m High Profile Soft Hose Boom Irrigator.

Dowdens Pumping & Water Treatment - RAINSPAN High Profile Soft Hose Boom Irrigator [Ilbilbie, QLD]

Details:

Sugarcane farmer Brian Stevens had for some time wanted to shift away from high pressure irrigation at his Ilbilbie farm, this was due in part to the high coastal winds the property endures year round playing havoc with his irrigation sprinklers. High pressure irrigation was no longer viable for this particular farm as it equated to water was being blown off crop, Brian's associated pumps working hard to deliver high pressure source water to existing soft hose irrigators and excessive mains power being consumed to run said pumps.

Moving from high pressure sprinklers to a low pressure RAINSPAN SB 2000 Dowdens has been able to deliver Brian considerable savings with his overall irrigation costs. The RAINSPAN SB2000 only requires approximately half the pressure to run compared to the previous high pressure irrigators. This has seen between a 30% - 40% decrease in farm irrigation electricity costs.

The low pressure RAINSPAN SB2000 Boom is far less susceptible to high winds, meaning Brian now has the potential to irrigate day or night, regardless of wind conditions. Essentially doubling his irrigation potential each day (the previous high-pressure system needed to be shut down during high winds experienced each night).

The RAINSPAN SB2000 Boom was found to be between 15% - 25% more efficient with its water application uniformity and distribution compared to the previous high pressure sprinkler irrigators. Simply put, Brian can now irrigate his sugarcane in a more cost-effective manner, utilising the limited water available to him more efficiently.

The RAINSPAN SB2000 is an extremely efficient and reliable low pressure irrigator that when installed and operated correctly saves farmers water, energy, time and money whilst increasing overall farm yields.

Key RAINSPAN SB2000 Boom Irrigator features listed below:

  • Nelson R3000 Rotator Sprinklers were fitted specially to suit the windy conditions, giving a large wetted footprint & better instantaneous application rate
  • Pulls 300m x 4" Snap-Tite Irrigator Hose (Dowdens are the sole authorised Snap-Tite hose dealer in Mackay, Whitsundays & Rockhampton)
  • Gearbox for smooth safe operation specifically designed for the Irrigator - the most efficient in the industry
  • A 93m boom was fitted to the RAINSPAN SB2000 - to seamlessly fit with farms existing lane spacings
  • New Generation Turbines that are the best in the industry
  • Hydraulic Boom Slew & Speed Compensator
  • Made in Australia

For well 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.

Specialised Pontoon Pumping System

Case Study

Customer: Peabody Energy Australia

Location: Moorvale Coal Mine, QLD

Specifications & Features:

Peabody Energy - Australia

Peabody Energy Australia have engaged Dowdens Pumping & Water Treatment's [Mackay] Engineering Department & Fabrication Workshop to deliver a Specialised Pontoon Pumping System for use at their Moorvale Coal Mine, located 156 kilometres South West of Mackay, QLD. This project presented a number of challenges for the Dowdens Mackay engineering and fabrication staff, including but not limited to an extremely tight delivery timeline of only 8 weeks!

Peabody Energy's Moorvale Mine is an open-cut coal mine that produces low-volatile pulverized coal injection (PCI) coal, coking coal and thermal coal for export markets. The Moorvale Coal Mine is particularly challenging for its operators due to the coal seam being quite narrow with a number of fault lines. This requires excavators often having to work in confined areas. The three piles that make up the Moorvale coal seams are mined independently of each other.

Dowdens Specialised Pontoon Pumping System was needed to provide Peabody Energy more reliable access to good quality Raw Water from an on-site dam. This raw dam water was then to be pumped directly to the onsite Coal Handling & Preparation Plant (CHPP). The existing supply water was limited and of poor quality. Dowdens new pontoon pumping system allowed for an increased volume of water to be pumped from a dam containing higher quality raw water. Subsequently the Specialised Pontoon Pumping System that Dowdens supplied has helped facilitate an improvement in the CHPP's daily operations.

"This particular project had a tight lead & build delivery timeline (approximately 8 weeks). During this time Dowdens were in regular contact with us, the project coordination and regular contact I received from Dowdens Engineers enabled me to better plan for the delivery and installation of the gangway and pontoon, which required a 100 tonne crane to be booked and ready onsite for the unloading and installation.

Dowdens Engineering Department was prompt and professional in helping resolve revisions in the project scope. The design and the way the pontoon was packaged and delivered added to the "Zero Incidents" achievement during the installation of the Pontoon on site. I was satisfied with the product, price and customer service provided by Dowdens Pumping & Water Treatment - Mackay"

Dowdens Pumping & Water Treatment - Specialised Pontoon Pumping System [Moorvale Coal Mine, QLD]

Details:

This project required both Dowdens Engineering Dept. & Fabrication Teams to deliver an innovative solution not previously attempted in-house. It was the first time Dowdens had manufactured 12m length gangways or a pontoon with a total weight of over 6 tonne. The total pontoon weight includes all steel work, flooring, pumps, piping etc. and is displaced using HDPE (high density polyethylene) Floats. The longest gangway Dowdens had supplied previously measured 8m in length, with the largest pontoon previously fabricated weighing in at 4.5 tonnes.

The new system meant Dowdens existing in-house designs had to be modified / improved with new floats being selected in order to safely carry the increased platform weight. Additional weight saving measures were implemented by Dowdens Engineers such as the use of light weight / high strength aluminium mesh flooring.

The timeline to design this pontoon pumping solution, manufacture the components and have them delivered to site was extremely tight. Engineering - Concept Design - Drawings & In-House Fabrication of the unique Pontoon Pumping System was completed & delivered to Moorvale Mine within their specified 8 week time frame!

No other pumping / manufacturing / engineering firm in Queensland are able to deliver such an all-encompassing product solution within 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.
