Waste Water Management Systems

Are you…

If you answered ‘Yes’ to any of the above and are within a non sewered area you must lodge an application with the Environmental Health Department.

No works are to begin unless a permit to install/alter has been issued, this permit remains in force for two years from the date of issue.

In order to apply for a permit to install a septic system you will need to:

Complete the Septic Application Form and pay the relevant fee
Undertake a Land Capability Assessment (LCA) and attach results
Submit a copy of the house plan
Submit a copy of the site plan showing the location of premises, boundaries and house dimensions including pools, driveways, bores, dams, creeks and rivers, storm water disposal, existing septic tanks, sheds and buildings and a detailed location of proposed septic tank systems and disposal area

Refer to the current application form for the fee or contact the council's environmental health unit on 02) 6022 9300 during office hours.

There are various types of systems available on the market, but all require Environmental Protection Authority approval

An LCA is not required if:

An Aerated Wastewater Treatment System (AWTS) is installed and 400m2 of cultivated and mulched garden beds are provided
In the case of alterations to existing systems, plumbing to the house is altered BUT house load is not increased (no extra bedrooms are added) and the system meets current EPA standards
Council's environmental health officer advises that an LCA is not required
You are installing a system which treats grey water only in a sewered area
You will be required to have a soil percolation test and have your soil type classified by a qualified soil technician

The septic system must not be used unless it has been inspected by the environmental health officer and a permit to use has been issued.
