Lower Burdekin Water cut their power consumption by 58,000kWh and demand by 105kVA resulting in annual cost savings of $20,000 (or 25%) at the Kilrie Gully Pumpstation. You can view the Case Study performed by Ergon Energy here
Rocks Energy Reduction
Red Lily Reconfiguration
- Project aims to reduce the overall power consumption at the Rocks PS
- Project will entail the installation of VSD’s on the pumps and subsequently the installation of ultrasonic flowmeters onto the rising mains
- Works scheduled for completion in 17/18 financial year.
Fords Gully Relift VSD
- Project focuses on addressing risks to LBW operations, road users, growers and improving system efficiencies.
- Preliminary design to decommission channel adjacent to Corica Road completed
- Gowers meeting held on the 30 June 2017 to discuss options to decommission channel
- Works scheduled for completion in 17/18 financial year.
Klondyke Lilliesmere VSD

Plain Road Culvert Upgrade
The Plain Road Culvert upgrade was a joint project undertaken by Lower Burdekin Water and Burdekin Shire Council. The project aimed to replace the existing damage culvert structure and allow for an increase to the capacity of the Warren’s Gully system. The project was completed on the 8th of June 2017, with the Warren’s Gully system re-opened on the 14th of June 2017. The project was completed under budget and within schedule. LBW would like to thank all effected growers for your cooperation during the works.
Kalamia Lagoon Regulation
Joint project between NQ Dry tropics and LBW to improve water control/efficiencies, water quality and fish passage in the bottom end of the Plantation Creek system. To achieve this aim, civil works on the Beach and Lilliesmere Road culverts including the construction of fish passages and regulator gate installations was required. Commissioning of the sites was conducted in April 2017
The Stage 1 upgrade of the McDowell Pipeline was completed on the 6th of July for a total shutdown of the McDowells system for 9 weeks. The project replaced approximately 1200m of the existing 1350 reinforced concrete (RC) pipe which was constructed in 1970, with 1300 glass reinforced plastic pipe (GRP). The project was completed under budget and within schedule. LBW would like to thank all effected growers for your cooperation during the works.
Lilliesmere Pump Station upgrade
The Lilliesmere PS upgrade was completed on the 27th of July for a total shutdown of the Lilliesmere system for 9 weeks. The Lilliesmere PS was originally constructed in the early 1970’s. The project involved the replacement of the existing discontinued pumps with three (3) submersible Flygt pumps, the removal of the existing switchroom and replacement with a new switchroom, installation of variable speed drives onto the new pump units and the refurbishment of the existing concrete pump-well structure. As a result of the works the pump stations capacity, reliability, maintainability, energy efficiency and safety to operational staff has been increased. The project was completed under budget and LBW would like to thank all effected growers for your cooperation during the works.
Ongoing Research Projects
The Northern Division is a statutory groundwater management authority, responsible for the economic and environmentally sustainable management of the groundwater resource within the proclaimed area of the Burdekin delta.
Over the recent years, salinity issues have become apparent in several coastal areas of the Lower Burdekin Delta. In the Airdmillan Road
area, which is close to the coast, steadily rising groundwater salinity levels have been reported.With the present salinity level, farmers have continued use of the groundwater for irrigation purposes. As part of its proactive management approach, the Northern Division wishes to put in place a strategy to ensure the groundwater resource continues to be used in a sustainable manner.
The Board commissioned CSIRO to investigate the probable cause of the salinity and make suitable recommendations towards future sustainable management in the area. The report confirmed a rising trend in groundwater salinity in the Airdmillan area. Although there is a lack of data, the report attributes the main cause to be the volume of water extracted from pumps in the area resulting in upconing of saline water from depth. The study made a number of recommendations to help manage the groundwater resource in the Airdmillan Road
area, including metering of pumped volumes, supplementing groundwater with surface water, continued monitoring of salinity and moderation of water use through efficient irrigation practices.
To better understand the whole system and then use that understanding to better manage the water resources in the region "Water Resources Observation Network (WRON) Burdekin Project" has been initiated by CSIRO. Rockwater Australia Pty Ltd has now been commissioned to further assess the findings of the CSIRO report taking particular account of geophysical factors. The report should be finalised in the near future. This consultancy will develop a conceptual water management plan for the Airdmillan area that will set in place a framework to address the rising salinity problem by sustainable use of groundwater, to be achieved by overall water usage conservation and partial substitution of surface water for groundwater. The proposed conceptual management plan will provide a framework for investigation, development, implementation and monitoring of water usage in the Airdmillan area.
