The Right Process to Stay Compliant (and Stress-Free)

Here’s how we take care of everything at Statewide Wastewater:

1. Site Assessment

   • We visit your block, check site slope, soil, setbacks, and sewer availability.

2. System Design

   • Based on soil test & house plans, we recommend a system that meets council approval.

3. Council Application

   • We handle the entire application process with Lockyer Valley or Toowoomba Council (all councils).

4. Installation & Commissioning

   • Full install of the tank, trenches or sprinklers, and pump station (if needed).

5. Ongoing Servicing (HSTPs only)

   • We offer regular servicing packages to keep your HSTP compliant.
     

📍 Where This Matters Most: Lockyer Valley & Toowoomba Region

🚜 Lockyer Valley (Gatton, Hatton Vale, Regency Downs, Withcott)

• Most blocks do not have town sewer

• Large growth in new builds & retreats

• Lockyer Valley Regional Council strict on compliance

• Many lots have clay or reactive soil = HSTP often required

🌿 Toowoomba (Highfields, Crows Nest, Cabarlah, Kingsthorpe etc)

• Popular for lifestyle acreage + NDIS housing

• Existing homes often have failing septic trenches

• Many dual dwelling builds need 2 systems or larger tanks

🧠 FAQs

❓ How long does approval take?

Typically 2–4 weeks depending on council workload.

❓ Can I install it myself?

No — only licensed professionals (like us) can legally install and certify wastewater systems in QLD.

❓ I’m building two homes — do I need two systems?

Possibly. It depends on the layout and council zoning. Contact us for advice before planning.
