    Sydney Water engaged the highly experienced Critical Sewer Solutions (CSS) delivery team in late June 2021 to continue and complete rehabilitation works inside the NSOOS tunnel, between Quakers Hat Bay, Mosman and Brightmore Reserve, Cremorne.

    CSS is comprised of specialist contractors Metrocorp and Interflow, companies that have a solid track record of working inside the NSOOS. They have successfully completed over 1.5km of tunnel rehabilitation at Lane Cove and Cremorne. This proven expertise will ensure the work is done safely and efficiently.

    The CSS team look forward to working closely with the community, ensuring minimal impact and disruption while we remove silt and debris, pressure clean and repair the tunnel
