Nikenbah Wastewater Treatment Plant, Hervey Bay

Nikenbah Wastewater Treatment Plant, Hervey Bay, Qld (2008 – 2009)

The 4.8 mega-litre per day Nikenbah Wastewater Treatment Plant (WWTP) was delivered under a $12m contract for the Wide Bay Water Corporation. The WWTP is able to treat wastewater from the equivalent of 10,000 houses, using an innovative membrane bio-reactor process and providing high quality recycled water for the irrigation of local farms and plantations. (These works were undertaken by the SGQ predecessor company, Bellero Constructions, with both Mark Goodwin – current SGQ Managing Director – and Bob Goodwin, as Directors of Bellero).

Scope of Work

60,000 m3 of imported fill to bring the site up to required levels
22m diameter balance tank
6m high multi-walled bioreactor and membrane tanks
Sludge digester
Chlorine contact tank
Suspended floor inlet works
Two storey control building
Blower and chemical buildings, and a sludge dewatering building

Notable Aspects

Significant Design & Construct tasks required for several major components
Major complex concrete and pipework
Detailed process infrastructure installed and connected, with associated M&E works
Significant building works
The project presented many challenges. Expertise from Bellero Construction’s civil and building sections enabled a complete package to be delivered to the client, with time and cost savings for the project, that was tightly governed by time constraints
Effective detailed coordination with mechanical and electrical subcontractors, together with Wide Bay Water’s specialist engineers and design consultants, ensured a successful project completion for all parties
