Approval to Operate

The NSW Government requires an 'Approval to Operate' an on-site sewage management system for all sewage management systems.

This means that Council must issue an Approval to Operate for every existing on-site sewage management system in the shire.

Currently there are around 4000 on-site sewage management systems on Council's register.

If you have an on-site sewage management system and have not submitted an application for approval to operate you are required to fill out the Approval to Operate System Sewage Management application form below and send it to Council.

New Owners - If you have recently bought a property that uses an on-site sewage management system, there is a period of three months in which to make an Application for an Approval to Operate.
