Need a septic system or HSTP installed? Learn how to get it approved — fast, hassle-free, and fully compliant.
🏡 Planning a New Home or Granny Flat in QLD?
If your property isn’t connected to the town sewer system, you’ll need a council-approved wastewater solution — either a septic system or Home Sewage Treatment Plant (HSTP).
But don’t stress — this guide shows you exactly what’s required and how to get your system approved quickly.

Step 1: Do You Need Council Approval?
YES — under Queensland law, all on-site wastewater systems require council approval.
This applies to:
New builds (homes, granny flats, sheds-turned-dwellings)
System upgrades (replacing an old septic tank)
Second dwellings on rural or acreage properties
Off-grid/remote properties with no town sewer
Step 2: Choose the Right System
You’ll typically choose between:
Septic Tank System
Lower upfront cost
Simple treatment & disposal
Good for suitable soils and larger blocks
HSTP (Home Sewage Treatment Plant)
Treats wastewater to high quality
Reuses water for irrigation
Required in sensitive zones or smaller blocks
👉 We install all major brands including Ozzi Kleen, Taylex, BioCycle, Aqua Nova, and more.
Step 3: Wastewater Design & Council Submission
