Mine Site Rehabilitation Solar Pump System

Case Study

Customer: Department of Environment and Heritage Protection

Location: Mount Chalmers Gold Mine - Mt Chalmers, QLD

Specifications & Features:

Dowdens Pumping & Water Treatment's Rockhampton branch were engaged by the Queensland State Government's Department of Environment and Heritage Protection to deliver an efficient solar pumping system at the disused Mount Chalmers Gold Mine (located 15km North-East of Rockhampton, QLD).

As part of this sites ongoing rehabilitation process the Department of Environment and Heritage Protection needed an efficient solar pumping system to recirculate contaminated mine water collected from a sump, back into the main pit, thereby eliminating any contaminated mine water runoff from site. The Department of Environment and Heritage Protection has been managing the key environmental issues at the Mount Chalmers Gold mine since the former operators Affinis Pty Ltd was placed into liquidation in December 2014. EHP is also supported by other government agencies including the Department of Science, Information Technology and Innovation (DSITI) who are providing scientific advice on technical aspects of site management. The primary ongoing focus is to prevent any discharge of contaminated water from the site.

With limited mains power available to the site the use of solar power was a perfect fit for this pumping application. Solar powered pump solutions are always improving, none more so than Grundfos Solar Water Solutions. During initial site inspections the pumps required operating duty was calculated to be 13L/sec @ 18.5m Total Head. To meet these high flow requirements a Grundfos Solar Inverter (RSI) was selected to power the Grundfos R Series Submersible Pump [SP46-3 5.5kw 415V] that the Department of Environment and Heritage Protection already had onsite. The Grundfos R Series SP46-3 is a Stainless Steel pump capable of handling the low pH, slightly acidic mine water (measuring between 2 & 3 pH) needing to be pumped.

Utilising a combination of Grundfos Solar Water Solution products (inverter / pump / solar panels) appealed to the Department of Environment and Heritage Protection as it meant Dowdens could supply a system that not only costs less to install and maintain, but importantly can pump a larger volume of water under solar power. Put quite simply the ability to run large 415V pumps capable of greater pump duties is making the decision to 'go green' and install solar powered systems more attractive in the current climate, for miners and farmers alike.

Dowdens Grundfos RSI Solar Pumping System - Mt Chalmers

Details:

Dowdens Pumping - Rockhampton initially visited site to establish location of the solar arrays and calculate pump duty. Once known the following components were sourced and prepared for installation: 36 x 270 Watt Grundfos Solar Modules, 2 x 18 SolarTerrace Module Fixed Array Frames, 7.5 kW Grundfos RSI Inverter & Sine Wave Filter and 200m of 110mm PN10 Poly Pipe. The Grundfos SP46-3 5.5kw Pump was attached to a specialised float that sits on the surface of the sump (pictured below). Pump starts & stops via a level float switch mounted on 4m pole that can be swivelled over to the sump's bank should any maintenance be required.

Local contractors were then engaged to complete the site earthworks and trenching needed for all electrical conduits. Once the solar array support posts were cemented in place, Dowdens Pumping - Rockhampton assembled the SolarTerrace Array Frames and mounted the 36 modules (2 x 18 Modules) ready for the electrical components to be installed.

Electrical contractors RILEC Electrical (accredited electrical/solar contractors) completed the electrical fit-out. As part of these works Dowdens Pumping - Rockhampton delivered the Grundfos Solar Inverter Sinewave Filter & String Connection Box (pictured below) to the RILEC workshop so it could be mounted in a powdered coated, lockable enclosure with sufficient ventilation to ensure the inverter remains cool during the day. RILEC then brought the control box to site, mounted it and completed all wiring to meet electrical standards and the site specifications. All commissioning of this system was undertaken by Dowdens Pumping - Rockhampton.

Dowdens Pumping & Water Treatment's Rockhampton branches design philosophy for this project was: Cost Effectiveness - Innovation - Ease of Installation - Simple & Reliable 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.

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!

Mackay Renal Unit UV Sterilisation System

Case Study

Customer: Queensland Health

Completion Date: 11/02/2014

Location: Mackay, QLD

Specifications & Features:

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!

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.

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.

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.

Broad Acre Irrigation Project

Case Study

Customer: Wilmar Sugar Australia Limited

Location: Gibson Creek, QLD

Specifications & Features:

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.

Unique Solar Pump Float

Case Study

Customer: Lance and Colleen Sypher

Location: Alpha, QLD

Specifications & Features:

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.

Dowdens Solar Array and Pump Float

Details:

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.
