Remote Solar Pumping System Installation

Case Study

Customer: Kurrajong Pastoral Company

Location: near Alpha, QLD

Specifications & Features:

Kurrajong Pastoral Company have engaged Dowdens Pumping & Water Treatment [Rockhampton branch] to design, install and commission a large solar powered stock watering system on one of their rural properties located near Alpha, QLD.

The solar powered stock watering system is required to transfer onsite bore water to existing water storage tanks. These water tanks are used by Kurrajong Pastoral Co. primarily to water the 1,000 head of cattle onsite.

Kurrajong Pastoral Co. specified each head of cattle was to be allocated a minimum of 10gal per day (approx. 45L/day), meaning the pumping system needed to deliver over 10,000gal per day (45,461L).

Water is pumped from the 5" onsite bore (pump set at 35m) with 75m total head into 3 storage tanks via poly line pipe.

Dowdens Pumping & Water Treatment - Solar Pumping System for Kurrajong Pastoral Co [near Alpha, QLD]

Details:

The Kurrajong Pastoral Co. solar pumping system was designed to keep overall operating costs down whilst still delivering a regular supply of water to cattle with negligible ongoing service or labour required. Dowdens Pumping & Water Treatment [Rockhampton] designed the system to be more cost effective than running additional wiring and connecting any onsite pumps to mains power.

The new solar pump replaces a B Head Mono Column and Shaft pump - originally powered by an onsite diesel engine. Dowdens solar powered system has thereby significantly lowered the environmental footprint of the entire pumping system.

Pressure Setting Spool Piece

Case Study

Customer: Anglo American - Grasstree Coal Mine

Location: Middlemount, QLD

Specifications & Features:

Anglo American - Australia

Anglo American have engaged Dowdens Pumping & Water Treatment's [Mackay] Engineering Department & Fabrication Workshop to rectify an issue with a new valve station installation that was experiencing water hammer, resulting in the longwall mining operation being suspended at their Grasstree Coal Mine, located at Middlemount in the centre of the Bowen Basin, QLD.

Underground mines require water management systems in place to manage working water that is utilised for production, dust suppression, hydraulic jacks etc. Mines employ various methods of underground water transportation systems including Longwall Boost Pump Stations & filtered water from the mine surface networks. The filtered water system is an important piece of infrastructure for underground coal mine providing clean water for dust suppression & feeding the powerful hydraulic piston pumps that are used to jack up the roof in the longwall mining process.

When water is fed into an underground mine it is received at a very high pressures due to the vertical drop to the mine workings. This pressure needs to be reduced & controlled to levels that can be safely managed in the underground operations. Dowdens Pumping & Water Treatment has provided Grasstree Coal Mine with several Pressure Reducing Valve Stations over the life of the mine, enabling reliable & trouble free operation.

Responding to the urgent help request from Grasstree Mine, Dowdens immediately travelled to site to undertake system 'fault finding' & begin planning the delivery of a timely & cost effective solution to the problem.

Dowdens Pumping & Water Treatment - Anglo American [Grasstree Coal Mine] Pressure Setting Spool Piece

Details:

As a direct result of Dowdens Pumping & Water Treatment's long standing & responsive working relationship with Anglo American's Grasstree underground coal mine, the Dowdens Engineering Department was called on to assist with a new valve station installation that was experiencing water hammer resulting in the longwall mining operation being suspended. Dowdens Engineers attended the mine site & listened/observed the problems that were being experienced such as pressure surges & water hammer in the feed pipes leading to the longwall operation.

Dowdens Engineering Dept. designed & developed a Pressure Setting Spool sized specifically to meet the specific duty required. The spool was custom designed using engineered fluid mechanics to reduce the pressure before it entered the valve station, taking part of the load off the station. Pipe supports were also engineered to provide a secure installation of the station.

The timeline to find the solution & manufacture the components was very tight. Engineering - Concept Design - Drawings & In-House Fabrication of the unique Pressure Setting Spool Piece [with roof bolt anchoring points] were completed & delivered to Grasstree Mine within 5 days from the first site meeting! No other pumping / manufacturing / engineering firm in Queensland was able to deliver such an all-encompassing product solution in the above mentioned time-frame.

Dowdens design philosophy for this project was: Fast Turnaround - Cost Effectiveness - Ease of Installation - Simple Plant Operation - Plant Reliability & Reduced Maintenance.

The unique system required at Grasstree Coal Mine needed to address the following issues:

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!

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.

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.
