This project entails construction of a new, 500EP Wastewater Treatment Plant to service the growing population in the Port Hinchinbrook region, replacing an adjacent that can no longer fulfil community requirements.

Being delivered alongside our frequent design partner GANDEN, the new facility is a 2-train Sequencing Batch Reactor (SBR) plant with tertiary filtration, disinfection, recycled water storage and pumping for disposal by irrigation. To achieve the initial 500EP operation, the plant will be commissioned, performance tested and operated a single train SBR, with Train No. 2 remaining offline until the future expansion to 1500EP.

Haslin is proud to be delivering this project in concert with the local community, haven’t engaged 10 key Sub-Contractors from the Cassowary Coast Regional Council LGA.
