Royal HaskoningDHV is delighted to announce the opening of the very first Nereda wastewater treatment plant in Australia. Located approximately 200km north west of Brisbane, in Kingaroy, known as the peanut capital of Australia, the new plant uses groundbreaking granular activated sludge technology to treat all of the town’s wastewater. As well as significantly reducing the amount of effluent discharged into the local river, it has enabled Class A recycled water to be used to irrigate local sports fields and a golf course.

Kingaroy’s original wastewater treatment plant was constructed around 1940 and has had many additions made to it since to support the town’s growing population. Gradual deterioration of the old plant’s infrastructure and poor effluent quality results meant that the plant required upgrading using 21st century technology to serve the local population of 12,500 people efficiently and meet stringent modern water quality standards.

The new plant has been designed and constructed for operator South Burnett Regional Council by Aquatec Maxcon, using the settling tanks from the old works. Within days of operation, the new plant met all its final effluent DEHP Licence conditions with low ammonia, total nitrogen, total phosphorous and faecal coliforms.

Mayor Keith Campbell said the plant was great addition to the local infrastructure as the water was clean enough that it can be used to irrigate parks, sporting grounds and gardens across the region.

Campbell: "It's a legacy project for future generations and the waste water industry, proving that small regional organisations can often be leaders in excellence".

Speaking on behalf of RoyalHaskoningDHV, which developed Nereda technology, Rosalie Rosink commented, “Nereda represents an evolution in activated sludge treatment. As well as significantly reducing the need of chemicals in the treatment of wastewater, it also has a dramatically reduced footprint and low energy requirements, reducing operational and capital expenditure.”
