Scando 450 Hoist and Platform from Alimak Hek

An Alimak Scando 450 hoist was used during the construction of a new pumping station at Quakers Hill Wastewater Treatment Plant. Alimak Hek engineered an 11m platform to enable the complete circumference of the pumping station to be formed up in stages around the centralized hoist.

Quaker's Hill Wastewater Treatment Plant has undergone a $52 million facility upgrade as part of Sydney Water's SewerFix program. The SewerFix initiative commenced in 2008 with the aim to protect public health and the environment by reducing overflows in the wastewater system by 2013. The $560 million program includes the installation of new pipes, the upgrading of wastewater pumping stations and improvements to the Sydney Water wastewater system.

Included in the Quakers Hill project is the installation of a new pumping station and systems upgrade to increase the capacity of the treatment plant. At present, the facility manages the treatment of approximately 1000 litres of wastewater every second. The new pumping station included in the total upgrade of the facility will greatly reduce the frequency of wet weather overflows in the Sydney wastewater system.

Alimak Hek installed a Scando 450 hoist on site at Quakers Hill, providing access for men and materials during construction of the pumping station. Commissioned in April 2012, the hoist was positioned in the centre of the 20m excavated pit, allowing the tank to be constructed up in stages. Four landing platforms were installed complete with landing gates and meshing, enabling work to occur simultaneously at different heights.

Alimak Hek engineered, manufactured and installed an 11m platform to bridge the gap between pit embankment and hoist. The inclusion of this platform walkway enabled the hoist to be positioned in the centre of the excavation pit, avoiding any interference with the formwork. The pumping station was then constructed from the base up in stages, with multiple landings installed as work progressed upwards.

Due to be completed in June 2013, the upgraded Quakers Hill Wastewater Treatment Plant will have the increased capacity to treat, store and disinfect more than 2200 litres of wastewater per second.
