South Gippsland Water invites tenders for the design, supply and construction of phosphorus removal and irrigation upgrades at the Meeniyan Wastewater Treatment Plant (WWTP).

The works include the design, supply, installation, commissioning and testing of a new Dissolved Air Flotation (DAF) package plant (within a building) to provide additional treatment to reduce phosphorus discharge levels to Stony Creek. The DAF system will include chemical dosing, flocculation, flotation, sludge management, and associated civil, mechanical, electrical and instrumentation works.
