Victor Harbor Wastewater Treatment Plant*
In December 2025, TRILITY successfully transferred the operations and maintenance of the Victor Harbor Wastewater Treatment Plant to SA Water, ending a 20-year partnership. TRILITY designed, built, and currently operates a wastewater treatment facility to treat sewage effluent to log six virus removal standards, making it suitable for unrestricted irrigation of private residences, community parklands, and golf courses. Department of Health regulations and further reuse options required the upgrade of the South Australian Victor Harbor plant in 2010/11 to meet the growing need for water reuse. TRILITY Designed and Constructed (D&C) the plant enhancement, which was financed by the client.
