Dowdens Pumping & Water Treatment's Rockhampton branch were engaged by local beef cattle graziers Kurrajong Pastoral (located near Springsure, QLD) to deliver a GRUNDFOS RSI Invertor Solar Pumping System at the Crystal Plains property to supplying onsite bore water to the property's many beef cattle watering troughs. Crystal Plains is a 3,018ha (7,458 acre) Springsure buffel grass property located 52km south of Emerald and 22km north of Springsure. The property comprises 10 dams, three bores, 14 grazing paddocks, plus several holding paddocks and water squares.
Dowdens Pumping - Rockhampton began the design of this solar pumping system with a site visit to record the height / depths of bores and to meet with the customers and garner their exact requirements for this system. Although not required for this particular bore inspection, Dowdens can offer our customers affordable Borehole and Drain inspection services using a range of Wireline Cameras. Our Wireline Cameras can operate up to a depth of 100m and deliver our customers high-resolution video and images straight to laptop / USB.
Once the proposal had been accepted, the Dowdens Industrial Workshop began sourcing the 18 x 270 Watt Solar Modules that were to be attached to 3 x 6 Module Fixed Post Array Frames. As an Authorised Grundfos Distributor Dowdens Pumping - Rockhampton were able to confidently recommend a Grundfos RSI Inverter together with the efficient SP7-17 415V Submersible Pump to be mounted and installed on this solar pumping system. The system pumps directly from a bore to an elevated position on Crystal Plains where the customer is then able to gravity feed from their established tank farm to the greater majority of his property. On average the pump transfers 50,000L/day.
Dowdens Pumping & Water Treatment's Rockhampton branch specialises in the design, manufacture and installation of innovative customised Solar Pumping systems for the commercial, agriculture and mining sectors of Central Queensland and the greater Capricorn Coast regions. Dowdens Rockhampton work closely with beef cattle producers to deliver innovative solar powered stock watering systems that not only minimise human interaction with cattle, but add value to the farms via efficient energy and water consumption.
The existing pump that Dowdens replaced was an old line shaft MONO pump that was operated by Diesel engine. The installation of the new Grundfos solar system lowered ongoing maintenance and operation costs considerably as the clients no longer had to replace the column due to the accumulation of rust. To ensure this wouldn't happen again Dowdens utilised stainless steel and poly pipe in the construction.
Operating costs were lowered via the system utilising a Grundfos Invertor with Sine Wave Filter Isolation Switch together with a tank level pressure switch - meaning the pump would start and stop automatically, only when needed. This automatic operation eliminated the need for the client to regularly drive to the bore to start and stop the pump. This increased pumping efficiency also saved on the overall cost of diesel to refuel the pump. The Grundfos Invertor with Sine Wave Filter Isolation Switch, together with the Grundfos SP7-17 415V Submersible Borehole Pump were pre-wired on a custom-fabricated steel mounting frame to enable easy 'plug & play' installation. Dowdens supplied 5km of poly pipe for both the tank fill line and the gravity feed lines.
Dowdens Pumping & Water Treatment's Rockhampton branches design philosophy for this project was: Cost Effectiveness - Innovation - Ease of Installation - Simple & Effective Pump Operation - System Reliability & Reduced Ongoing Maintenance. The entire Grundfos RSI Solar Pumping System was designed, manufactured, installed and commissioned on time and within budget.

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:
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.
