Delivering complex sewer diversion works in a constrained urban environment to enable major residential development in Zetland.

Zetland, Sydney, New South Wales




The Green Square development in Zetland included four mid-rise residential towers and a three-level basement carpark. Existing sewer infrastructure running through the site required relocation to allow construction of the basement structure.
Killard was engaged to deliver the sewer diversion works, relocating the carrier main outside the development footprint while maintaining the integrity of the surrounding sewer network.
