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.
Sheraton Grand Mirage Resort (Port Douglas) - Sewage Pump Stations Key Components:
Cannonvale was amongst the hardest hit regions during Cyclone Debbie, so it was no surprise to Dowdens Pumping & Water Treatment's Proserpine Branch to hear Queensland Health had been advised they couldn't be guaranteed potable water supply to their Whitsunday Community Health Centre located in Cannonvale immediately after Cyclone Debbie.
Luckily Dowdens Pumping & Water Treatment's Head Office in Mackay had a portable Ultrafiltration Treatment System available, capable of supplying up to 70,000 litres of potable water per day. Queensland Health and the Whitsunday Community Health Centre in Cannonvale instructed Dowdens Pumping to supply/install the unit immediately on a temporary 'Hire' agreement in-case all mains water supply was lost.
There were two water sources available at the time - the mains water supply or bore water from the Proserpine Hospital. Queensland Health instructed Dowdens to connect the UF Treatment System to the bore water supply, in an effort to remain as self-sufficient as possible post-Cyclone Debbie.
Dowdens Pumping have previously completed numerous bore water filtration systems treating bore water with our own brand of PURION Iron Removal Filters, so this emergency UF Treatment System was quick and easy to install. PURION Iron Removal Filters pre-treat the bore water before running it through the Ultrafiltration System which then doses the filtrate with liquid chlorine to further disinfect.
Once treated Dowdens Pumping manually transported numerous loads of the potable water from the Proserpine Hospital (where the UF System was installed) directly to the Whitsunday Community Health Centre in Cannonvale, where it was stored in a potable water grade storage tank. The treated water was then used to supply the medical centre. The entire supply/installation and commissioning was successfully completed on Saturday 1st of April - only 4 days after Cyclone Debbie had hit.
If you are ever in need of potable water during a storm or emergency contact Dowdens Pumping & Water Treatment. Dowdens only require access to a reasonable source of water (bore, dam, creek) and power (generator or mains power) and we can guarantee same day potable water supply, in any situation!
Dowdens Pumping and Water Treatment have successfully designed, manufactured and commissioned a self-contained Solar Emergency Eye Wash and Safety Shower. The safety station incorporates both safety shower and eye wash facilities, which are supplied from a water tank via a solar powered Grundfos pump.
This unit was designed and manufactured to comply with Australian Standards AS4775-2007.
Dowdens supplied the portable Solar Eye Wash and Safety Shower station to Downer EDI Mining Blasting Services for use at the Rio Tinto Coal Mount Thorley open cut coal mines (located 15km South West of Singleton in the Hunter Valley region of NSW).
Project's Supply Scope:
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 Mackay Branch has completed commissioning of the Moranbah 'whole-of-town' Automated Irrigation System. This Dowdens designed irrigation system was delivered to improve the control and ongoing maintenance of township irrigation within Moranbah, QLD.
Isaac Regional Council (IRC) specified a number of key criteria during the tendering process that the system was to deliver. These system criteria included, but were not limited to: provide the ability for night time automatic irrigation to numerous local Athletics Fields that have previously been irrigated manually (using static sprinklers and travelling irrigators) during the day; to replace an aging irrigation system located on Mills Ave. and achieve an overall reduction in labour relating to ongoing maintenance.
Dowdens Mackay successful tender was centred on an innovative Central Control System that enabled remote monitoring and maintenance of the 52 irrigation sites throughout Moranbah. The Dowdens designed controller is based in the Goonyella Road Council Depot. Dowdens Central Control System comprises of a desktop computer, irrigation software, an online weather station and localised communication/data collection infrastructure (routers, modem and radio transmitters/receivers).
This irrigation system is the first time Central Control System architecture has been utilised anywhere in the Isaac Regional Council shire. The system transmits all data collected / collated via several forms of communication i.e. radio frequencies, internet connection (Wi-Fi / 3G) and direct wired connections.
The Dowdens designed Central Control System has the ability to communicate to all Toro Sentinel Controllers via either radio frequency or internet connection. The operator has the ability to program and monitor all controllers via the Central Controller. The operator can set independent watering days, start times and run times for each and every station (valve) connected to Sentinel Controllers. Each day a detailed activity report is sent to all operators notifying them of all system activities, such as no. of actual stations operated, how long for, if any stations recorded abnormal flow (high or low), system communication success or failures, abnormal solenoid coil current (high or low) and the status of all soil moisture sensors. Reports can easily be generated to show the history of all/specific system activities such as those listed above.
A wireless Weather Station and remote Soil Moisture Sensors were installed and connected to the Central Controller to efficiently monitor the regions weather conditions in real-time, and then adjust the systems parameters accordingly. The Weather Station and remote Soil Moisture Sensors are used primarily to prevent irrigation occurring during and after localised rain events and to calculate Evapotranspiration (ET) based irrigation running times. For example the Central Control System is programmed to turn all irrigation off for 3 days (adjustable timeframe) when more than 10mm of rain is received on any 1 day (adjustable timeframe). Weather Station calculates the daily ET and automatically adjusts irrigation duration accordingly (lower ET = lower run time).
This systems has provided IRC control and monitoring capabilities of 52 irrigation sites throughout Moranbah from one central site. Delivering vastly improved energy and water use efficiencies this Dowdens designed irrigation systems features automatic shutdown of all irrigation during rain events; automatic adjustment of irrigation run times based on ET; daily automatic reporting of all irrigation sites activity; automatic irrigation for 75% of median strips located on Mills Avenue; addition of quick coupler valves to flush lateral lines thereby minimising blockages; automatic irrigation of Little Athletics / AFL Sporting fields resulting in reduced labour required for manual setup of irrigators; reduction of effluent contact with public via system only watering at night; filters on effluent mainline have minimised blockages to irrigation valve and sprinklers, thereby reducing labour required to clear blockages.
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 Greatly Reduced Ongoing Maintenance Requirements.
Moranbah Township Irrigation ~ Key System FEATURES & Components:
CENTRAL CONTROL ROOM Components
TORO Sentinel Water Management System software - EATON Computer with Printer, Router, UPS - DAVIS Vantage Pro2Plus Weather Station Console (Inside Temperature, Humidity, Barometric Pressure Sensors) - DAVIS Vantage Pro2Plus Integrated Sensor Suite (Anemometer, Tipping Rain Collector, UV Sensor, Solar Radiation Sensor, Outside Temperature Sensor, Outside Humidity Sensor) - WEATHERLINK Software - TORO NSN Support Systems (24/7 Phone Support for IRC operators)
FIELD CONTROLLERS Overview
Field (or Satellite) Controllers were installed at 52 sites throughout Moranbah. These units control the irrigation at their respective sites by direct wire connection to solenoid valves. The field controllers act as stand alone units, operating independently from the central controller. However all of the Controller's programming information comes via the Central Controller. This allows Field Controllers to operate even if the Central Controller is not operational for any reason (loss of power, phone network outages etc.). The Central Controller and Field Controllers automatically communicate at the end of each day to tabulate current programming changes, and again each morning to receive detailed system activity reports. The Field Controllers can be powered by AC if available on site, or DC via by 12V batteries trickle charged by solar panels.
Controllers were either mounted on existing structures or on Dowdens fabricated galvanised steel posts, hinged to allow access from ground level. Each of the 4 irrigated Sports Field sites have a wireless soil moisture sensor attached. The Field Controllers can be set to prevent watering when the soil moisture is above 50% of capacity (all are adjustable). A Mobile Soil Moisture Sensor was also supplied to allow IRC operators to manually test and record soil moisture levels at any location. All Field Controllers have a built in radio for communication to a 'Base' or 'Node' Controller. Base Controllers also have a 3G modem to communicate with the Central Controller.
MILLS AVENUE - MEDIANS IRRIGATION Overview
This portion of the project involved the design, supply and installation of 17 irrigation systems for all median strips on Mills Avenue, Moranbah (running from Goonyella Road to Clements Street). The existing systems were old, had unreliable battery powered controllers and required high levels of IRC operator maintenance. Most of the medians were generally turf with established large trees, approximately 10 metres wide, ranging anywhere from 10 - 230 metres long.
Each median irrigation system that Dowdens supplied consisted of: DC Sentinel Controller with radio, battery, panel, antenna, hinged pole, connection to existing Effluent mainline, flow sensors, isolation ball valves, solenoid valves / valve boxes, Toro T5 pop-up sprinklers with flexible risers and quick coupler valves placed at the end of the lines for flushing purposes.
LITTLE ATHLETICS / AFL FIELD IRRIGATION Overview
This portion of the project involved the design, supply and installation of an irrigation system for the Moranbah Little Athletics Field. The existing system consisted of a large travelling irrigator, which involved the IRC operator setting up the machine, manually turning it on and off and moving it to each position on the field. This produces uneven watering and often resulted in irrigation needing to undertaken during the day which goes against the applicable effluent re-use guidelines.
The irrigation system that Dowdens supplied incorporated: AC Sentinel Controller with radio & antenna (also incorporating AFL coverage), connection to existing Effluent mainline, 80 mm semi-automatic filter, flow sensors, isolation ball valves, solenoid valves / valve boxes, Toro 640 pop-up sprinklers with articulated risers and a wireless soil moisture sensor was installed on the AFL field to monitor soil moisture content.
MAINLINE FILTERS Overview
This portion of the project involved the design, supply and installation of semi-automatic filters at various locations along the effluent mainline. A 200 mm filter was installed in the mainline behind Moranbah High School, a 100 mm filter at Tallon Street and an 80 mm filter at the Athletics / AFL Field. Each of these filters included galvanised steel pipework to allow filters to be mounted above ground, isolation valves, filter, concrete pad and a Dowdens fabricated lockable enclosure. The filters are easily cleaned by opening a valve / turning a handle to allow the suction scanners to clean the entire filter without needing the removal of the element - a huge time saver for the IRC operators.
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.
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.

Racecourse Projects recently engaged Dowdens Pumping & Water Treatment's Mackay 'Infield Service Crew' to undertake emergency repairs to a damaged Valley Irrigation Centre Pivot Irrigator at their Sugar Cane Farm located in Marwood, QLD.
This project began, like most emergency repair jobs do with an unexpected call from our customer. Racecourse Projects rang the Dowdens Pumping Agricultural Sales Team to inform them a Cane Haul-Out Truck had struck the first span of their Valley Centre Pivot. The pivot was now hanging precariously and needed to be repaired immediately. Daryn Gray (Dowdens - Industrial Workshop [Engineering Support]) and Brett Hayes (Dowdens - Agricultural Sales) promptly attended the Marwood site and assessed the pivot. Dowdens advised the pivot needed to be supported or it may have collapsed further. Straightaway the Dowdens 'Infield Service Crew' were onsite to elevate and secure the damaged span.
After speaking directly with the manufacturer of the damaged Valley Centre Pivot (Valmont Industries - Australia) Dowdens confirmed with Racecourse Projects there were no suitable spans for that machine currently available anywhere in Australia. This meant repairs needed to be undertaken promptly before the machine potentially collapsed completely - making any further repair work impossible. Dowdens then promptly engaged a local subcontractor to work alongside the Dowdens 'Infield Service Crew' repairing the machine in situ (whilst still suspended in the air). As the repairs had to be effected whilst the machine was still standing, this required coordination between 2 cranes and a telehandler forklift, along with a man box (attached to the all terrain telehandler) for 2 men to carry out the repairs. All the repairs and commissioning of the irrigator were successfully completed within 2 days of the accident!

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.
