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.
