Septic Tanks

For properties not connected to the mains sewer system, a properly functioning septic tank system is essential for safe and efficient wastewater management. At Mackie Plumbing and Gas, we specialise in the installation, replacement, and upgrade of septic tanks across Perth and regional WA — providing fully compliant systems built to suit your site, usage, and soil conditions.

Septic tanks work by separating and partially treating household wastewater before dispersing it into leach drains or soakage trenches. Whether you’re building a new home, replacing an old tank, or upgrading your system to meet local shire or health department requirements, our team can manage the entire process from start to finish.
