A major $6.5 million upgrade is now underway to future-proof the Sewage Treatment Plant in Singleton.
The work marks the latest phase in Singleton Council’s ongoing capital investment into critical wastewater infrastructure.
It’s believed the project, which includes a $1 million contribution from the Australian Government’s Community Energy Upgrades Fund (round 2), incorporates a program of energy efficiency, electrification and automation improvements that will reduce emissions, cut operating costs and improve its resilience.
Council’s director infrastructure and planning services Mike Duff said the venture would ensure the 40-year-old facility continued to perform safely and efficiently for the growing community, even though customers may not notice it when they turn on a tap or flush the toilet.
“Originally constructed in 1984, the Singleton Sewage Treatment Plant is essential infrastructure for our current population and the foundation of future residential and economic growth,” he explained.
“These upgrades will significantly improve the site’s reliability, automate key processes and reduce energy use and emissions.
“It’ll also ensure we have a modern, efficient facility that will continue to protect public health and the environment for decades to come.”
At the heart of the work is a transformation of the aeration system.
It’s the Singleton Sewage Treatment Plant’s largest energy user, accounting for about 80% of total electricity consumption.
The upgrades are estimated to reduce energy usage by 60%, cut costs by almost $100,000 annually and avoid 93 tonnes of CO2 emissions per year.
Mr Duff said the project further demonstrated council’s commitment to responsible, forward-looking infrastructure planning while delivering essential services to the people of Singleton.
“This upgrade isn’t just about replacing old components,” he added.
“It is about transforming how the plant operates to minimise environmental impact, reduce long-term costs, and build resilience into a system that our community depends on.
“With the support of the federal government, the Sewage Treatment Plant project has a payback period of approximately 10 years.
“And, the upgraded systems are expected to exceed that in life cycle, delivering lasting value for the Singleton community.”
The commissioning of the modernised systems is expected in late 2026.
