Whether you're in the Scenic Rim, Somerset, South Burnett, Moreton Bay, Gympie Sunshine Coast Hinterland, Logan, Brisbane Or Ipswich this 2026 guide has everything homeowners, builders, and developers need to know about septic tanks, HSTPs (Home Sewage Treatment Plants), installation costs, servicing, council regulations, and more.


We created this guide to answer all your questions and make managing wastewater systems in Queensland easy, compliant, and stress-free.


Septic Tank vs HSTP – What’s the Difference?

Septic Tank System: A traditional underground tank where solids settle, and liquids disperse into trenches.

HSTP (Home Sewage Treatment Plant): A modern system that actively treats wastewater to a higher standard. Treated water can be safely reused on gardens and lawns.


How Do Septic Tanks & HSTPs Work?

Step 1 – Wastewater Flow: From toilets, showers, sinks, kitchens, and laundry.

Step 2 – Separation & Treatment:

  • Septic: Solids settle; effluent flows into absorption trenches.

  • HSTP: Wastewater passes through multiple chambers, including aeration and disinfection.

Step 3 – Disposal or Reuse:

  • Septic: Effluent soaks into the soil.

  • HSTP: Treated water can be reused for irrigation.

Wastewater Types:

  • Blackwater: From toilets

  • Greywater: From showers, laundry, and sinks
