BIOSeptic’s Septic Tank Access Saddle provides a simple, durable and compliant way to locate, access and maintain septic tanks—especially on properties where the tank is buried below ground with no visible marker.
Designed for homeowners, pump-out contractors and maintenance technicians, the Access Saddle raises the entry point of your septic tank to ground level, ensuring maintenance can be carried out safely and efficiently without excavation.
BioSeptic developed the access saddle with Access Septic Products, an Adelaide-based septic product specialist company. Together, we have conducted extensive research and development—including 18 months of design and rigorous testing—to bring the access saddle to market.
On 29 January 2017, SAI Global provided accreditation for the saddle as an accessory to a horizontal axis septic tank, under the Australian Standard for septic tanks. To maintain our Product Certification for the saddle, we have in place a quality assurance scheme that is regularly audited by SAI Global.
The saddle is approved by SA Health with approval number WWP P0002.
Australian Standards
Our septic tank access saddles help you meet Australian Standard AS/NZS1546.1 (relating to the design, performance and testing of septic tanks), which requires that all septic tanks have access openings that allow for regular de-sludging of the tank.
The South Australian Government (SA Health) requires that all septic tanks are de-sludged every four years.

Why you need an access saddle
An access saddle allows you to:
Bring your tank access position up to ground level for easy access and identification.
Have a strong and durable cover for your septic tank.
Prevent unauthorised septic tank access—our saddle is water-tight and triple bolted in position.
Stop stock falling into your tank.
Protect children from accessing your septic tank—our saddle is secure and unable to be removed without tools or by children.
Save time and money through having easy access to your tank, for maintenance, monitoring and repair.
Comply with Australian Standard AS/NZS1546.1 and SA Health regulations (South Australia).
Cars, machinery and appliances are serviced regularly to prolong their life and to keep them safe and reliable. Your septic tank is no different. It requires servicing (de-sludging) to keep it functioning correctly, to protect your family’s health.

Product Details
Why Septic Tank Access Matters
In many parts of South Australia, Victoria and Queensland, septic tanks were historically installed fully buried, making them extremely difficult to locate and maintain. This leads to:
Unnecessary excavation costs
Delayed pump-outs and servicing
Risk of tank overflows and disposal-area failure
Non-compliance with council requirements
Health and odour issues for households and neighbours
A septic tank’s performance relies on proper maintenance—especially periodic de-sludging. Without reliable access, many tanks go years without service, increasing the risk of:
System failure
Smelly or boggy disposal areas
Contaminated groundwater
Expensive repairs or full system replacement
The BIOSeptic Solution
A Permanent, Above-Ground Access Point
The BIOSeptic Septic Tank Access Saddle fits over your existing septic tank opening and raises the access point to ground level. Once installed:
Your tank’s location is always visible
Pump-outs no longer require digging
Routine inspections take minutes
Council compliance is easier to meet
You will never need to dig up your septic tank again.
