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!

Specifications & Features:

Boonal Joint Venture Coal Load Facility

Dowdens Pumping & Water Treatment's Rockhampton branch working closely with Dowdens Pumping - Mackay's Industrial & Fabrication Workshops have successfully designed, manufactured and commissioned a Customised Dewatering Pump System for YANCOAL Australia. YANCOAL own and operate the YARRABEE Coal Mine & Boonal Joint Venture Coal Load Out Facility that is located 40 kilometres north-east of the township of Blackwater, QLD in Central Queensland's Bowen Basin. The Boonal Joint Venture is a coal load out facility located on the Capricorn Highway in Central Queensland, Australia. Coal from both the Yarrabee Coal Mine and Jellinbah Coal Mine are transported via rail link to the Port of Gladstone from the Boonal coal load out facility.

After initial site visits Dowdens Pumping - Rockhampton were able to measure the height and distance required for the dewatering pump system, as well as clearly establish pipe sizes and required flow rates to adequately meet the clients onsite dewatering requirements. This led to the in-house design of the unit by Dowdens Pumping - Mackay's Engineering Department. Once the proposal had been accepted by the client CAD drawings were immediately created and passed onto the Dowdens Industrial Fabrication Workshop.

Boonal Joint Venture's Customised Dewatering Pump System Supply Scope:

  • The Yanmar diesel engine recommended by Dowdens Pumping - Rockhampton ensured long term problem free operation
  • All fabrication, assembly and performance testing was conducted by Dowdens Pumping & Water Treatment in-house & onsite guaranteeing product quality

Boonal Joint Venture - Coal Load Facility Dewatering Pump

Details:

As Dowdens Pumping are an authorised FLOWSERVE Pumps Distributor, we were able to quickly and easily size and source a FLOWSERVE Hydro Titan Pump. The Hydro Titan 100x65-250 Pump has a capable duty of 14 l/sec (@ 50m total head) and perfectly matched the clients site requirements. From here Dowdens Industrial Fabrication Workshop welded the skid base together which was then bunded and fully hot dip galvanised. This innovative system utilised a universal coupling, installed between the pump and motor to reduce the chance of miss alignment occurring between the pump and engine.

Dowdens Industrial Fabrication Workshop then proceeded to assemble and mount the 125l diesel fuel tank, Yanmar 3TNV84TEPP-PE 3-Cylinder Diesel Engine, Hydro Titan 100x65-250 Pump and install the universal coupling. Dowdens Electricians then connected the battery and solar array charger module to the canopy [pictured below], whilst mounting the Yanmar 'Engine Protection Unit'. The engine was then taken outside and tested. Once all this was completed it was transported to site where final commissioning was successfully completed.

The complete Boonal Joint Venture's Customised Dewatering Pump System was designed, installed and commissioned by Dowdens Pumping 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 - Engine Longevity - System Reliability & Reduced Ongoing Maintenance.

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.

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!

Moranbah Township Irrigation System

Case Study

Customer: Isaac Regional Council

Location: Moranbah, QLD

Specifications & Features:

Isaac Regional Council - Dowdens Moranbah Irrigation System

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).

Dowdens Pumping & Water Treatment - Whole Town Irrigation System [Moranbah, QLD]

Details:

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.

Moranbah Irrigation System - Field Controllers Overview

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.

Moranbah Irrigation System - Median Strip Irrigation System Overview

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.

Moranbah Irrigation System - Sports Field Irrigation Systems Overview

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.

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.
