Highfields mixes suburban streets with acreage blocks. Many larger blocks rely on septic tanks or AWTS. We haven't been able to confirm sewer boundaries street by street.
Acreage systems around Highfields
On larger rural-residential blocks, an AWTS with sprinklers or drip irrigation is common, as is a septic tank with trenches. Council notes AWTS are the most common system type in the region. Treatment plants need regular servicing and must stay switched on. Effluent must stay inside the approved area and your boundary.
If you're buying an acreage home, ask for the system's service records and approval, and check the irrigation area is not under driveways, sheds or new lawn areas.

- Septic pump-outs: Toowoomba Regional Council says septic tanks should be desludged every 3 to 5 years by a licensed liquid waste contractor. Pump-out guide.
- AWTS servicing: treatment plants are commonly serviced every 3 months, and the owner must keep a service agreement in place. AWTS servicing guide.
- Problems: smells, gurgling, wet trenches or alarms. What they can mean.
- New or replacement systems: need council plumbing approval first. How approvals work and typical cost ranges.
Getting a provider out to Highfields
Send the form or call with your address, system type (if known), and what's happening. We pass it to an independent licensed provider who works in the area. They quote and book directly with you. Ask for their licence details and a written quote before work starts. Travel distance and access (gate width, tank location, wet ground) can affect availability and price.
