Major sewer projects
Council is making a $160 million investment in sewerage infrastructure to support the growing Clarence Valley population and business base, both now and into the future:
Junction Hill to North Grafton Transfer Scheme
This $3.8 million project was handed over to Council in January 2008. Remediation of three former STPs at Junction Hill will be undertaken as part of the Grafton and Maclean project.
The $77.5 million Grafton Maclean Lawrence Townsend Ilarwill sewerage project included closing four Sewage Treatment Plants (STP) at South Grafton, Maclean, Townsend and Ilarwill which were unable to meet modern environmental standards, constructing one new STP at Woodford Island and augmenting two existing STPs at Clarenza and North Grafton, sewering the town of Lawrence and constructing associated transfer systems. Construction of the project was completed in June 2010. The project featured extensive innovation in planning, design, procurement and project management and has resulted in significant environmental, sustainability and community benefits. Despite extensive wet weather during construction, the project was completed under budget.
This $45 million scheme comprises reticulated sewerage and a new STP for the currently unsewered township of Iluka, with recycled water reuse on the Golf Course, playing fields and in a dual reticulation system. Construction of the scheme commenced in April 2011. The STP was handed over to Council in March 2012, and the reticulation is scheduled for completion in early 2013.
This scheme comprises augmentation of the existing Yamba STP and some upgrading of the associated reticulation in Yamba. Detailed design was finalised in early 2012. Biosolids Management facilities at the STP and extension of sewerage to Oyster Channel are being constructed in 2012, with the remainder of construction proposed to commence following completion of the Iluka scheme.
