Detailed Design of Hallidays Point STP (conversion of IDEA to MLE) with John Wilson & Partners (now WhorleyParsons) for MidCoast Water (NSW).

Hallidays Point STP is one of the many treatment facilities servicing the thriving Forster-Tuncurry coastal region of NSW. ASpect, as part of a team headed by John Wilson and Partners and including MWH Australia, was awarded the detailed design and documentation of the Hallidays Point sewage treatment plant upgrade. This major upgrade was a significant step in MidCoast Water’s ongoing investment in social and environmental improvement. The Halliday’s point scheme involved the following elements: the decomissioning of the trickling filter facility at Tuncurry and conversion into a stormflow storage facility, construction of a 20 km rising main to transfer Tuncurry sewage to Hallidays Point (to improve treatment and reduce the odour annoyance to local residence at Tuncurry), the amplification of the existing Hallidays point STP to increase capacity, improve nutrient removal performance, facilitate remote supervisory control and generally improve reliability, and the expansion of the existing dune injection and plantation transpiration system as an alternative to discharge. The facility controls ensured the STP could operate largely unmanned.
