Kingscliff Holiday Park Caprari-CPC Pump Station

Case Study

Customer: Hardings Earthmoving (o/b/o Tweed Coast Holiday Parks)

Location: Kingscliff, NSW

Specifications & Features:

Harding's EarthmovingHarding's Earthmoving submitted a successful tender to Tweed Shire Council for the decommissioning and redevelopment of the Kingscliff North Holiday Park, which included the installation of a new Sewage Pump Station (on behalf of Tweed Coast Holiday Parks).

This standalone Sewage Pump Station was to completely replace the Holiday Park's aging and outdated sewage system.

Harding's Earthmoving subsequently engaged Dowdens Pumping & Water Treatment [Brisbane branch] to design, supply, install and commission a specialised Precast Concrete Sewage Pump Station for use in the Holiday Park's redevelopment. Dowdens Pumping & Water Treatment have partnered with Caprari-CPC to become the sole QLD and Northern NSW distributor and specialised servicing agent for the new patented Caprari-CPC concrete packaged pump stations.

Tweed Shire Council

Crucial tender selection criteria stipulated by Tweed Shire Council was for the new complete Sewage Pump Station to be successfully operating for at least 50 years and the concrete chamber to provide a minimum working life of 100 years.

The patented Caprari-CPC Pump Stations are cast using a special S50 cement with a minimum concrete strength of 50MPa and utilises an Angaston Marble calcareous aggregate; offering the highest possible resistance to sulphate attack endemic in Australian sewers. Caprari-CPC Pump Stations are specifically designed to withstand harsh environments, including poor soil conditions and high water tables (engineered to 15m depth). Caprari-CPC Pump Station chambers feature steel reinforcing with an internal concrete cover of 65mm to provide additional protection; this unique feature extends their design life to over 100 years - perfectly suiting Tweed Shire Council's tender selection criteria's.

Once selected by Tweed Shire Council the Caprari-CPC Pump Station was designed, sourced, installed (all onsite earthmoving works undertaken by Harding's Earthmoving), commissioned and the entire project managed by Dowdens Pumping & Water Treatment [Brisbane branch].

"During the lead build time (which was 1 week ahead of schedule) Dowdens were in constant contact. Tweed Shire Council made a few changes along the way which were accommodated and organised promptly and precisely every time by Dowdens. The coordination and regular contact I received was second to none. The team at Dowdens were not just salesmen, they actually knew not only how to trouble shoot, but also how to resolve any last minute changes whilst always chasing me up with courtesy! I was more than impressed with the product, price, amazing service and the installation provided by Dowdens Pumping & Water Treatment. I have been in this game for 25yrs and cannot recall getting more professional service in any other field or from any other business than what I received on this project, a rarity. Thanks Dowdens!"

Details:

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.

TRAILCO Soft Hose Irrigator

Case Study

Customer: Sarina Sugarcane Farmer

Location: Sarina, QLD

Specifications & Features:

TRAILCO Soft Hose Travelling Irrigator

Dowdens Pumping & Water Treatment [Mackay] have delivered yet another Soft Hose Travelling Irrigator to a local Sarina Sugarcane Farmer.

Harvey Matsen [pictured below] operates a 100ha sugarcane farm in Sarina. Due to the lack of rainfall during the 2014/15 growing season he decided to purchase a TRAILCO T-450-2 Soft Hose Travelling Irrigator to better manage the irrigation of his cane.

Wanting to purchase his new irrigator from a local business Harvey sought the services of 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. For 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.

Jeff Roberts from the Dowdens Mackay Agricultural Sales Team visited Harvey's farm on a number of occasions to investigate, design and then match an irrigator and irrigation plan to best suit the property. Taking into consideration the terrain, existing pump capabilities and source water availability Jeff suggested Harvey purchase a TRAILCO T-450-2 Soft Hose Travelling Irrigator with irrigation gun.

Dowdens Pumping & Water Treatment - TRAILCO Soft Hose Travelling Irrigator [Sarina, QLD]

Details:

Harvey has access to pressurised irrigation water from the nearby Kinchant Dam. At farm door the dam feed water arrives at between 20 - 30psi. With the TRAILCO T-450-2 Soft Hose Travelling Irrigator needing a higher pressure to operate efficiently Dowdens utilised the farm's existing Power-Take-Off (PTO) Tractor driven booster pump, raising the feed water to over 70psi.

The T-450-2 is able to apply 50mm of water onto a 2ha area of cane whilst travelling along 300m of 4" soft hose - delivering 22.5L/sec @ 70psi.

Together with flood irrigation (using the gravity fed Kinchant Dam feed water), an existing travelling irrigator and the new T-450-2 Harvey can now irrigate his property in half the time. In times of low rainfall when young cane is most vulnerable to dry soil conditions, Harvey can now irrigate his young cane faster ensuring they take root quicker and go on to deliver a better overall yield.

The T-450-2 is an extremely efficient and reliable soft hose travelling irrigator - so much so it can easily pull Harvey's tractor towards it as it travels down the feed hose on an irrigating run [pictured below].

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.
