The Kendall Bay Sediment Remediation Project has been recognised internationally, taking out the silver for 'Sustainable Change for Good' at the 2021 Edison Awardsâ„¢.
The award was presented to our client Jemena for the design and delivery of the Marine Insitu Stabilization used in the remediation of Kendall Bay.
Understood to be the world's first subaqueous insitu stabilization (ISS) of sediment for environmental purposes, Ventia's Environmental Services team played a key role in the design and delivery of this project. Working with Jemena, we designed and delivered a long-term sediment remediation solution which minimised the impact on the environment and the local community.
ISS is a commonly used, highly successful method on land however there are only a few small-scale examples that have been completed in a marine environment. Through careful planning and working closely with our client, the Kendall Bay team were able to address the many challenges associated with working within the bay itself.
The ISS involved mixing of marine cement with the sediment underwater to form a stabilised raft-like structure to permanently contain the contaminated sediments.

About Kendall Bay
Kendall Bay is a shallow marine environment characterised by intertidal mudflats, mangroves, outcropping sandstone rock, a sandstone seawall and a sandy beach. At approximately 10km west of the Sydney Central Business District on the south side of the Parramatta River, the Kendall Bay Remediation project involved the remediation of legacy coal tar contamination that was left behind from the operation of the former Mortlake Gasworks.
The project was successfully completed in October 2020 with great feedback received from the surrounding community.
