The Taroom Sewer Treatment Plant Upgrade is a Banana Shire Council initiative to replace ageing infrastructure, which is 50 years old. The purpose of the project to and improve effluent quality giving consideration to the Great Barrier Reef 2050 Water Quality Improvement Plan, which aims to protect and restore the Great Barrier Reef, in part by reducing the amount of nutrients discharged to the reef.
The scope of work includes:
- Design management (principal contractor with the assistance of design partners), including:
- Civil – piling, earthworks, site drainage
- Structural – mechanical/electrical shed, concrete structures
- Process – inlet works operation, bypass control, moving bed biofilm reactor (MBBR) process, clarification, solids handling, chemical dosing, instrumentation, SCADA control
- Mechanical/electrical – MBBR mechanical/electrical components, pumping, valving and pipework, blowers, belt press, chemical dosing
- Installation of new below-ground pipework, including potable water lines, process pipe work for effluent discharge and process transitions, electrical conduits, and stormwater drainage
- Installation of new bypass weir and manual screen in a high-risk area, working over water, with operational constraints
- Installation of process tanks including anoxic tank, MBBR process tanks, and thickened sludge tank
- Installation of process pumping stations, including RAS pumping and belt press feed
- Installation of process area concrete structures including anoxic tank founding slab, process area founding slab, and M&E building slab
- Installation of founding piers
- Installation of safety equipment, including safety showers, wash down hoses, and safety signage
- New sodium hypochlorite dosing system
- Above ground pipe and valving installation, including all plant inlet, anoxic tank, MBBR process tanks, clarifiers, blowers RAS, sodium hypochlorite dosing (including injection point) manifold and pipe transitions.
