WT22-24/25 Yarranlea WTP Separation and Filtration

Summary and scope

Scope of the works will include the supply and installation of a new DynaSand, or equivalent filter and lamella separator, along with the decommissioning and removal of the existing units. Connecting pipework shall be replaced as required, to install the new units and improve condition of connections. Appropriate drainage for each unit is to be installed. All components are to be supplied and installed to commission new pipework, dynamic sand filter and lamella separator. Commissioning is to be conducted by the contractor with Council representative and testing. One system of ladder and walkways should be used to safely connect and access both sand filter and lamella separator. This is to be supplied and installed to suit the new units. In the interests of water security, Council require the works to be programmed over the cooler months of July and August 2025. Offline works are to be aimed for July 2025. This would give an allotment of 2 weeks of offline works for removal and installation if required.
