Concrete septic tanks with cast-in bases are used for onsite wastewater systems where an approved precast concrete septic tank is required. The range includes individual septic tanks and selected two-tank combinations with standard or traffic-rated split lid cover options.
These septic tanks are selected by internal diameter, depth, capacity, inlet height, outlet height, cover type and approximate weight. The tanks are approved to Australian Standard AS/NZS 1546 and comply with Department of Health requirements under the Code of Practice for Product Approval of Onsite Wastewater Systems. Confirm tank sizing, approval requirements, site access, lifting and unloading arrangements before ordering.
