Septic Tank Tips for Gold Coast

Gold Coast hinterland properties are largely on septic — Gold Coast City Council requires on-site sewage facility permits and regular pump-out records

The high water table in low-lying coastal areas can make absorption trench installation difficult — a soil assessment is essential before any new installation

Gold Coast's warm subtropical climate accelerates bacterial action in septic tanks which is beneficial, but heavy summer rainfall can overload systems — ensure your system is sized for peak wet-season loads
