Big lift for Gladstone wastewater upgrade

Big lift for Gladstone wastewater upgrade

Gladstone Regional Council this week completed its largest lift in more than 30 years when the 92-tonne roof of its Gladstone Wastewater Treatment Plant digester tank was removed for refurbishment of the facility.

The council said the lift was the largest since the effort required to place the roof on the same structure in the early 1980s.

LCR Group was engaged by the principal project contractor Aquatec Maxcon to perform the lift, which will allow the digester to be cleaned to allow a condition assessment of the tank.

The 500-tonne crane used to carry out the task took three days to assemble, but the actual lift was over in less than 15 minutes, a council spokesman said.

This exercise was one component of the works being completed as part of the Gladstone Wastewater Treatment Plant upgrade, which council is completing with assistance from the Queensland Government’s Building Our Regions program.

The digester tank is being repurposed as an anaerobic digester as part of the new biosolids handling facility design.

The steel roof removed from the tank will undergo a condition assessment to determine if it has sufficient structural capacity to meet the design life requirements for the new facility.
