Sydney Water – North West Treatment Hub Growth Program

Formwork, Reinforcement & Concrete (FRP) – Dryer & Carboniser Facilities

Kelko Construction was engaged by John Holland to deliver specialist formwork, reinforcement and concrete (FRP) works for the dryer and carboniser facilities as part of Sydney Water’s North West Treatment Hub Growth Program at the Riverstone Water Resource Recovery Facility.

This scope formed a key component of the sludge treatment and thermal processing infrastructure and involved the construction of multiple reinforced concrete structures supporting electrical, mechanical and process systems within a highly coordinated construction environment.

Key elements of the scope included:

• HV and LV Switchrooms – FRP works for critical electrical infrastructure
• 1st Flush Tank – reinforced concrete process tank construction
• Heater Building – structural concrete works supporting thermal treatment systems
• Dryer Building – FRP construction for sludge drying operations
• Dried Sludge Silo Slab – heavily reinforced slab supporting storage infrastructure
• Carboniser Building – structural concrete works for thermal carbonisation processes
• Outloading Silo Slab – reinforced slab construction for material handling and dispatch
• Peroxide Bund – bunded containment structures for chemical storage
• Fire Water Tank Foundation Slab – structural slab supporting fire protection systems
• Effluent Water Slab – reinforced concrete slab for process water management

The works is currently being delivered across multiple staged milestones and requires close coordination with adjacent trades and systems to meet program, safety and quality requirements. Kelko Construction’s involvement highlights our capability in delivering complex, high-value FRP packages for water, wastewater and industrial process infrastructure.
