Septic Tank Tips for Canberra

Canberra's outer rural residential areas (RZ5, RZ6 zones) are predominantly on-site sewage systems — ICON Water's sewer network does not extend to most rural properties

ACT Environment Protection Authority requires all on-site sewage facility modifications to be approved by Access Canberra — allow 4–6 weeks for approval

Canberra's cold winters mean slower bacterial activity in septic tanks — consider a slightly larger tank or more frequent pump-outs if you have a large household
