What the notice says

This tender process is for the provision of Supply & Install of Modular Treatment Equipment: Fixed‑Film Biological, Preliminary and Primary Filtration Systems. A summary of the scope across all Lots forming part of this tender is stated below. The Modular Treatment framework will consist of suppliers who have the ability to design, supply & install containerised assets on a flatbed vehicle as a standalone solution either be removed via roll on/roll off functionality or craneage. This framework will also consider semi modular assets which are assembled/installed by the asset supplier and involve greater civil complexity due to these assets requiring partial burying, but typically without the requirement for additional shuttering that's associated with traditional concrete assets. These assets will either be purchased by the Utilities directly and the novated or free issued to the Utilities Capital Construction supply chain partners.
