Duplex Stainless Steel Overflow Tank

Architectural Water Management Solution for a Luxury Residential Development

Emerald Fabrication was engaged by Lendlease to fabricate and install a duplex stainless steel overflow tank at One Sydney Harbour, Barangaroo.

Installed within a penthouse apartment, the tank was designed to act as an overflow system for the swimming pool, allowing excess water to be captured and recycled rather than discharged. The solution required precision fabrication, premium materials, and careful coordination to integrate seamlessly within a high-end residential environment.

This project demanded strict attention to detailing, durability, and performance while meeting the architectural and functional expectations of a landmark waterfront development.
