Rookwood Weir
From 2021 to 2023, Logitech Engineering have assisted Sunwater to construct the new Rookwood Weir
on the Fitzroy River in Central Queensland.
The weir structure is 350m long, and will store over 75,000 megalitres of water when full. Logitech Engineering have assisted
McCoskers and
GHD Engineering to design the electrical power system, security and control systems for the site,
as well as the Fishlock and Turtle passage for the Weir.

Biogas Clean Energy
In 2015, Logitech Engineering joined forces with Prizm Engineering and Zinfra to design and commission Queenslands newest Biogas energy recovery systems in Rockhampton and Brisbane for Teys Australia. These large scale units convert abattoir discharge effluent from the Teys meat works to generate methane for boiler feed gas. The biogas is burned to create steam for the plant, while the cleaned and phosphate reduced water is safely discharged to the river.
Water Treatment
The process involves pumping waste discharge from the Teys meat processing plant, removing the solids, and using bugs
to convert the product into Biogas. The biogas is collected under two large covered ponds, and burned in a boiler to produce steam.
The energy is passed back into the plant as process steam, and also used as wash-down water.
Suspended solids, ammonia-nitrogen, total nitrogen and total phosphorus are all significantly reduced. Dissolved solids,
dissolved oxygen, nitrate-N, iron, zinc and cadmium are also reduced in the process.
Sewage Treatment
In 2015, Logitech Engineering joined forces with John Holland, GHD and CNF to build and commission the new Googong Water Recycling plant in Canberra. This state-of-the-art sewage treatment facility located near Queenbeyan NSW uses a combination of bioreactors, membrane filtration, chemical dosing and UV exposure to clean the waste water. In fact, the water is clean enough to use as sprinkler water for gardens, and you could even drink it if you were really thirsty.
