Introduction
Lismore Septic Systems
If your property isn’t connected to the main sewer line, a well-designed septic system is essential for managing wastewater safely and efficiently. At Origin Plumbing & Gas, we install, upgrade and maintain septic systems for homes and rural properties in Lismore and the wider Northern Rivers region.
Whether you're building on a new block or replacing an ageing system, we’ll assess your site, soil type and household usage to recommend the right setup. Our licensed plumbers handle the entire process—from excavation and tank installation to drainage trenches and council approvals. With routine servicing, your system can perform reliably for decades. We also provide support with stormwater drainage, backflow prevention and leak detection to keep your wider plumbing running smoothly.

Frequently Asked Questions
How often should a septic tank be pumped out?
Most tanks need to be pumped every 3–5 years, depending on size and usage. Regular pump-outs prevent overflow, odours and costly damage.
Can I build over a septic tank or drain field?
No—structures or driveways should never be built over septic components. Access is required for maintenance, and weight can damage the system.
What are signs of a failing septic system?
Slow drains, bad smells, wet patches near the tank or soggy soil above the absorption trench often indicate your system needs attention or repair.
