Cleveland Bay which was part of the Water Matters Alliance in Townsville, included mechanical design, equipment and installation including switchboards, PLCs & SCADA and the Kubota flat sheet membranes for the membrane bioreactor at Horseshoe Bay. This plant has received many awards including the Excellence Award for a Major Water Project Greater than $5M and the Alliance Project Team Excellence Award. Also becoming finalists in the 2009 Australian Water Association – Water Environment Merit Award and the 2008 Australasian Alliancing Association Awards.

Delivery of the programme of works included:

• Brownfield capacity and quality upgrade of Cleveland Bay WRP to 126,000 EP Biological Nutrient Removal (BNR);
• Membrane Treatment system retrofitted into the existing clarifiers which we reconfigured to become bioreactors. The plant combines an oxidation ditch with membrane separation. A biosolids handling facility was undertaken also. Effluent from the plant can be treated in a future water reclamation facility which will include reverse osmosis to achieve reuse water suitable for industrial and irrigation applications. The efficient equipment selections have resulted in the operating costs being substantially below the initial projections with savings approaching $1m per annum.
• The Cleveland Bay WTF was, at commissioning, the largest MBR in the Southern Hemisphere and one of the largest MBR plants in the world.
• The scope also included an upgrade of the plants control, SCADA and telemetry systems by MPA Engineering.
• Effluent Achieved: Total N (mg/l – 3.5); Total P (mg/l – 0.5) discharging to Great Barrier Reef Marine Park
