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!

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].

Whitsunday Gardens Caprari-CPC Pump Station

Case Study

Customer: Relag Group Pty Ltd

Location: Proserpine, QLD

Specifications & Features:

Whitsunday Gardens Estate situated in Proserpine, QLD is a new land release subdivision located just 25 minutes from the iconic Airlie Beach.

Relag Group Pty Ltd are responsible for this new urban housing development and subsequently engaged Dowdens Pumping & Water Treatment [Proserpine branch] to design, supply and install a Precast Concrete Pump Station for use in Stage 3 of the Whitsunday Gardens Estate subdivision development.

Stage 3 of the subdivision development required a standalone sewage pump station to be installed capable of handling the residential waste water and sewerage borne from 20 subdivided lots. The land was used to farm sugarcane before the development began in 2013.

Whitsunday Regional Council Water and Sewage Executive ManagersBefore the design and construction phases could begin Dowdens met extensively with the Whitsunday Regional Council's Water & Sewage Executive Managers to discuss the suitability of the Caprari-CPC Sewage Pump Station, the design peculiarities required for the working in the region (a high water table onsite) and how Dowdens could adapt the Caprari-CPC system to best suit the site requirements.

Multiple options were presented in the initial design drawings helping to satisfy Whitsunday Regional Council (WRC) specifications; including locally designed and engineered aluminium access covers requested by the WRC [ensuring uniformity with all other waste water assets held in the region], inhouse manufacturing of specific handrails to meet municipal safety codes and working with WRC's preferred switchboard manufacturer [Belmont Electrical].
