Blue Mountains
Blue Mountains septic and AWTS questions often come down to sandstone escarpments, World Heritage bushland and drinking-water catchments. Typical work here includes septic pump-outs, AWTS servicing, repairs and upgrades.

Soils and ground conditions in Blue Mountains
The Blue Mountains are Hawkesbury and Narrabeen sandstone with thin soils and steep slopes.
Unsewered properties in the upper and lower mountains rely on septic or AWTS systems, and parts of the area sit in Sydney’s drinking-water catchment.
Climate and on-site systems
Cool, wet winters, summer storms and bushfire risk, including the 2019–20 fires, affect on-site systems.
A tank only works as well as the absorption or irrigation area after it: saturated, compacted or root-filled ground is the most common reason for slow drains, odours and wet patches, so the soil and the water table are checked as well as the tank.
Local approvals and rules
Blue Mountains City Council approves and inspects on-site sewage management systems.
In New South Wales, installing or operating an on-site sewage management system needs council approval under section 68 of the Local Government Act 1993. Aerated wastewater treatment systems (AWTS) must be accredited by NSW Health and are serviced on a regular schedule, and councils inspect systems through their on-site sewage management programs.
Typical septic and AWTS work in Blue Mountains
Septic pump-outs, AWTS servicing, repairs and upgrades. Every property is different, so the system is located, opened and inspected on site before any repair is recommended or quoted.
Know where your tank, lids and absorption or irrigation area are, keep vehicles and structures off them, and have any service records ready before the visit.
