Tender Details
Tender Description
Central Highlands Water requires a specialist wastewater treatment design and construct contractor to undertake the design, construction, testing, commissioning, proving and defects liability for the replacement mechanisms and refurbishment of two of the four existing Primary Sedimentation Tanks. The chain-and-flight sludge collector mechanisms for PSTs 1 & 2 have reached the end of their service life and need to be replaced.
Baffles will also be installed in PST1 & 2 to enhance flocculation and increase primary total suspended solids (TSS) removal. A ventilation system in the dewatering building will also be installed to reduce the risk of corrosion and improve the operating environment for operations and maintenance personnel.
