Unitywater is putting the finishing touches on a six-year infrastructure project designed to future-proof its operations.
The Queensland utility, which provides water and sewerage services to 17% of the state’s population, is on the homestretch of an upgrade to the greater Caloundra area’s sewerage network.
The upgraded network will service the Sunshine Coast communities of Caloundra, Golden Beach, Aura, Pelican Waters, Little Mountain and Bellvista.
Unitywater Executive Manager Sustainable Infrastructure Solutions Scott Barnes said the utility had invested $30 million across five major projects to ensure the sewerage network meets the needs of a growing population.
Works included new sewer mains in central Caloundra, a new odour control facility in Aroona and relining the Kalana Road sewerage main.
A new sewerage pipeline was also built between Caloundra and Aroona, using the longest horizontal directional drill of its kind in Australia.
“Upgrading the sewerage network improves its efficiency and lowers maintenance costs into the future,” Barnes said.
“Importantly, the new infrastructure minimises the risk of sewage overflows in extreme weather and tackles odour and corrosion concerns.”
The final step is a new 15-metre deep sewage pumping station at Duck Holes Creek, which is expected to be completed by the end of the year.
