Septic Tank Removal Services
When a septic tank reaches the end of its life, needs to be replaced, or a property connects to the mains sewer, safe and compliant removal is essential. At Mid Valley Septics, we handle the entire septic tank removal process (from pumping out residual liquid waste to decommissioning and disposal) so you can move forward with confidence and full regulatory peace of mind.
Serving Coffs Harbour and across the Mid North Coast, our licensed team brings 25+ years of hands-on experience to every job.
What Does Septic Tank Removal Involve?
Septic tank removal is the safe decommissioning and physical extraction (or in-place neutralisation) of an existing septic tank system. Depending on the tank’s condition, material, and your property’s requirements, removal may involve:
- Pumping out all remaining liquid waste and solid sludge
- High-pressure cleaning of the tank interior
- Disconnection of all inlet and outlet pipes
- Physical excavation and removal of the tank from the site
- Environmentally compliant disposal of all waste and materials
- Backfilling and site reinstatement
In some cases, particularly with older concrete tanks in good structural condition, decommissioning in place (filling the tank with sand or concrete) may be a suitable and council-approved alternative to full removal. Our team will assess your property and advise on the most practical and compliant approach.
When Do You Need Septic Tank Removal?
There are several common reasons a property owner may need to remove or decommission a septic tank:
Connecting to Mains Sewer
When a property gains access to the mains sewer system, local council regulations typically require that the existing septic tank be decommissioned. Leaving a disused tank in the ground without proper removal or neutralisation can pose a safety and environmental risk, and may affect property sales and insurance.
System Failure or End of Life
A septic system that is failing (due to structural damage, persistent overflows, or age) may need to be fully removed and replaced. Ongoing repairs to a failing system can quickly become more expensive than a complete removal and fresh installation.
Property Development or Renovation
Building extensions, new structures, or significant landscaping work sometimes uncovers or conflicts with existing septic tank infrastructure. In these cases, removal is necessary to proceed safely and with council approval.
System Upgrade
Upgrading from an older, less efficient wastewater treatment system to a modern aerated wastewater treatment system (AWTS) or an alternative solution often requires removal of the existing tank to make way for the new installation.
Safe, Compliant Liquid Waste Disposal
Septic tank removal isn’t just a physical job. It’s a regulated process. Improper handling of sewage, wastewater, and solid waste from a septic tank can result in ground contamination, water pollution, and serious fines under NSW environmental regulations.
At Mid Valley Septics, all liquid waste and solid sludge removed during the process is transported and disposed of at a licensed waste treatment facility in accordance with the Protection of the Environment Operations Act 1997 (NSW). We handle all required documentation and regulatory obligations on your behalf, so you have complete peace of mind.
We also liaise with your local council where required and can advise on any approvals or permits needed before works commence.
Regular Maintenance: The Best Way to Avoid Premature Removal
Many septic tank removals are the result of systems that were neglected over time. With routine septic tank maintenance, most systems can serve a property reliably for 20–40 years, delaying or avoiding the need for costly removal and replacement.
Key maintenance practices that protect your septic system include:
- Septic tank pump-outs every 3–5 years to remove accumulated sludge and prevent overflow
- Annual or bi-annual inspections to identify early signs of failure
- Regular septic tank cleaning to maintain effective wastewater treatment
- Avoiding flushing harsh chemicals that disrupt the bacterial balance in the tank
- Keeping heavy vehicles and deep-rooted plants away from the drain field
Mid Valley Septics offers ongoing servicing and maintenance plans to keep your septic system performing at its best. Our experienced team services all common system types across the Coffs Harbour region and surrounding areas.

Septic Tank Removal: Frequently Asked Questions
How much does septic tank removal cost in NSW?
Costs vary depending on the tank’s size, material, depth, and accessibility, as well as the volume of liquid waste and sludge that needs to be removed. Contact us for a free, no-obligation quote specific to your property.
Do I need council approval to remove a septic tank?
In most cases, yes. Particularly if you’re decommissioning a tank when connecting to the mains sewer. Mid Valley Septics can guide you through the approval process and liaise with your local council on your behalf.
How long does septic tank removal take?
A straightforward removal typically takes one to two days. More complex jobs involving larger tanks, difficult access, or significant excavation may take longer. We’ll give you a clear timeframe before work begins.
Can a septic tank be left in the ground?
In some circumstances, decommissioning in place (filling the tank with sand or concrete after pumping) is a council-approved alternative to full removal. Our team will assess whether this is suitable for your property.
What are the signs that my septic tank needs to be replaced?
Persistent bad odours, wet patches over the tank or drain field, slow-draining fixtures, or sewage backing up inside the property are all warning signs that your system may be failing and require assessment.
