The Cedar Grove Wastewater Treatment Plant in Logan, Queensland, has reached a new milestone, with construction now reaching the halfway point.
The infrastructure is being built in two sections, with the first pipeline between Greenbank and Flagstone to be 10km in length.
The pipeline that will link Flagstone to the Cedar Grove plant will be 9km long. Four pump stations will also be built along the route.
Logan City Council’s Water Infrastructure Alliance has planned, designed and constructed the pipeline under direction from Economic Development Queensland.
Works have included a combination of open trench, tunnel boring and horizontal directional drilling (HDD) construction methods.
The future Cedar Grove Environmental Centre will set a new benchmark in providing an efficient sewage treatment service that will also enrich its surrounding natural environment.
The centre’s wastewater facility will operate under the strictest environmental license ever granted by the Department of Environment and Science, which requires it to achieve a “net environmental benefit” for its local catchment.
Wastewater will undergo a biological treatment process before being released to the river via man-made wetlands, where native plants will polish the treated water to a very high standard.
It will be one of the best-performing wastewater treatment plants in Australia and will deliver environmental benefits to the river and its catchment.
The pipeline is due for completion in May 2020, ahead of the plant becoming operational mid-year.
