Air and water quality, chemicals and sewage

The Orient Cave was the first cave in the world to be 'steam cleaned' to help protect the fragile cave system. This is a technique which Jenolan pioneered, and it ensures that visitor skin particles, hair and lint do not change the delicate equilibrium of the cave ecosystems.

In association with the National Parks and Wildlife Service Karst and Geodiversity Unit, seven water, eight air and seventeen radon monitors have been installed in the cave system.

The Jenolan Environmental Audit program includes monthly inspections of chemical storage, waste disposal, leakage from pipes and other potential environmental issues.  We act on problems as they arise and prevent adverse environmental impacts.

Downstream from the caves, our small sewage plant provides primary and tertiary treatment followed by UV. For more information you’re welcome to review the Sewage Treatment Plant Analytical Results.

A purpose-built water treatment facility has been installed. This has been in operation since July 2023. The unit was designed and manufactured by an Australian company AquaManage and delivered in a shipping container.
