A septic tank that runs on bacteria, not electricity.
No pump. No power connection. No cleaning trucks. The Microbes bio septic tank breaks waste down naturally — odour-free, maintenance-free, and installed in a single day.
Built to be forgotten about
Once it's installed, a Microbes tank isn't something you think about again. That's the whole point.
Runs without power
The digestion process is entirely biological. No pump, no electricity bill, no failure when the power goes out.
No cleaning trucks, ever
Bacteria break waste down continuously, so sludge doesn't accumulate the way it does in a conventional tank.
Genuinely odour-free
Complete anaerobic breakdown means no foul gases escape — safe next to living spaces, kitchens, and bedrooms.
Water you can reuse
Treated outflow is clean enough to route to a soak pit or use directly for garden irrigation.
Low, predictable upkeep
No moving parts to service. What maintenance exists is minimal and infrequent, not a recurring cost.
Works where sewage lines don't
No government sewerage connection required — built for standalone homes, layouts, and institutions alike.
How the digestion works
Waste moves through three chambers, broken down at each stage by a living bacterial culture.
Waste enters
Household waste flows in through the inlet into the first chamber.
Bacteria break it down
An inoculum culture digests solids anaerobically across the three internal chambers.
Gases vent safely
By-product gases release through a vent pipe — no odour reaches the surface.
Clean water exits
Treated water leaves through the outlet, ready for a soak pit or garden use.

Installed on time with a team that stayed in touch through the whole process. Pricing was fair compared to what we'd been quoted elsewhere.
Switched to a bio tank on our engineer's advice because of our soil type. The team explained the process clearly before we committed, and installation went smoothly under tough conditions.
No damage to the surrounding area during install, and the crew addressed every question we had, including worst-case scenarios. Quality exceeded what we expected for the price.
