Septic Tank Installation & Servicing

A reliable septic system is essential for properties without access to mains sewerage, and getting it right from the start can save you years of headaches (and expensive repairs). At Off Grid Plumbing, we design, install, and service septic systems for both residential and commercial sites, ensuring everything runs smoothly, efficiently, and in compliance with local regulations.

Professional Installation You Can Rely On

We take the time to assess your property, soil type, usage requirements, and council regulations before recommending the best septic solution. From excavation and tank installation to connecting the system and ensuring proper drainage, every step is handled with precision.

Ongoing Servicing & Maintenance

Like any critical system, your septic tank needs regular servicing to keep it working effectively. We offer scheduled maintenance to inspect, pump, and clean your tank, check for leaks, and make sure the system is performing as it should. A little maintenance goes a long way in preventing costly breakdowns.

Why Septic Tanks Are Still a Smart Choice

For rural properties, commercial sites without access to the main sewer line, or environmentally conscious businesses, septic tanks offer an effective and self-contained wastewater solution.

A well-designed and correctly installed septic system can:

  • Manage wastewater efficiently without relying on municipal sewerage

  • Reduce ongoing water costs

  • Protect the surrounding environment from contamination

  • Last for decades with proper care

But these benefits only come if the system is installed and maintained by an experienced, licensed plumber. That’s where we come in.

Septic Tank Servicing & Maintenance

Like any essential system, septic tanks need regular servicing to avoid costly breakdowns or overflows. Our maintenance services are designed to keep your tank running smoothly and extend its lifespan.

We provide:

  • Routine inspections

  • Pump-outs and desludging

  • Drain field checks

  • Filter cleaning/replacement

  • Repairs and part replacements

Signs your septic tank needs servicing:

  • Slow draining sinks and toilets

  • Foul smells around drains or outside near the tank

  • Pooling water or unusually lush grass near the drain field

  • Sewage backups inside the property

If you notice any of these signs, it’s best to call us immediately — catching an issue early can save thousands in repair costs.

Frequently Asked Questions

In most cases, installation takes 1–3 days, depending on site conditions and council approval timelines.

Yes. All new septic installations must comply with local council and environmental health regulations. We handle the entire approval process for you.

A septic tank uses natural bacteria to break down waste and release treated water into the drain field. An AWTS (Aerated Wastewater Treatment System) uses additional mechanical treatment and aeration to produce cleaner water, which can be reused for irrigation.

It’s not recommended, as tree roots can damage pipes and the tank. If you want landscaping near your system, choose plants with shallow root systems.

Common signs include foul odours, slow drains, water pooling over the drain field, and sewage backing up inside the home.

Water tank install & solar hot water heater

We have hired Tom and the team at Offgrid plumbing to do a variety of jobs over recent years. The jobs included installing our water tanks, installing a solar hot water heater, replacing roof gutters that were badly constructed and installing standing seam cladding to waterproof our house’s upper storey. Each job was quite complex. We were very happy with the team’s problem solving, their attention to detail and the very high quality of their work.

Gas Leak Repair

Off Grid plumbing investigated a gas leak at my apartment and then installed a new gas line. They were fantastic from start to finish. Tom answered all of my phone calls, provided helpful advice and did the installation work the day after he came to quote for it. They did a very neat job with the new gas line. They were also happy to do some extra bits and pieces that I asked for. Would highly recommend!
