Securing a Sustainable Water Future
Mackay Regional Council’s long-term water demand study showed that Marian and Mirani’s existing groundwater bores couldn’t keep pace with projected growth—and aquifer quality was slipping. To safeguard reliable, high-quality drinking water, an alternative water source from Pioneer River was needed.
Our Solution: New Marian Water Treatment Plant, Lamella Package plant with small footprint; Lamella plate sludge thickener.
By tapping the Pioneer River at Marian Weir, the new Marian Water Treatment Plant (WTP) delivers clean, safe drinking water to both townships. Aquatec Maxcon was chosen to design and build the 25 km-inland facility, ensuring it meets today’s needs and tomorrow’s growth.
What’s Inside the Plant
• Lamella Clarifier – Rapid solids removal for clearer water
• Multi-Media Filter – Fine polishing to remove remaining particles
• Chemical Dosing Package – Precise pH and coagulant control
• Fluoridation System – Protects community dental health
• Gas Chlorination – Reliable disinfection against pathogens
• Advanced Electrical & Control Systems – Automated, 24/7 monitoring
• Sludge Drying – Efficient handling and volume reduction
Civil & Site Works
• Flood-resilient Site Raising – Elevates the entire plant above peak flood levels
• Administration Building – Modern offices and staff amenities
• Workshop/Store – Secure storage and on-site maintenance hub
• Switch Room – Dedicated control room for power and SCADA operations
• Access Roads & Drainage – All-weather connectivity and stormwater management
Project Benefits
• Future-Proof Capacity – Delivers up to 4 ML/day, surpassing forecast demand
• Improved Water Quality – Consistent clarity, taste, and safety
• Resilience to Drought – Year-round river source, independent of groundwater levels
• Community Health – Fluoridation and reliable disinfection standards
