What the Sunshine Coast asks for
Sewer covers the coastal strip, but the hinterland — Maleny, Mapleton, Eudlo, Kenilworth and thousands of acreage blocks between — runs on on-site sewerage facilities. Council's on-site treatment and greywater page lays out a three-step path: a licensed site and soil evaluator assesses the block and recommends the treatment level, you lodge the Form 1 permit application, and a licensed drainage contractor installs the approved facility and handles inspections and certification.
The council's guidance is unusually clear on treatment levels, which matter here because of the region's creeks and sensitive coastal catchments: primary treatment (a septic tank with below-ground disposal), secondary treatment (suitable for surface or subsurface irrigation) and advanced secondary (suitable near sensitive ecosystems). Your soil evaluator's report determines which level your block needs — steeper, wetter hinterland sites often can't take a simple trench system. Compare the system types in our systems guides before you price anything.
- Servicing runs from quarterly (AWTS) to yearly depending on system type, and service reports must reach council — its eServices channel processes them instantly, while hard-copy and emailed reports attract an administration fee under the development services fees and charges
- Greywater treatment or diversion in unsewered areas is part of the same permit framework — don't plumb anything in without approval
- Council doesn't publish a single OSSF application fee on the page; the Development Services fee register holds the current amounts, so confirm with council or let your installer quote it

Common questions
What treatment level will my hinterland block need?
That's the site and soil evaluator's call. Flat blocks with good soil may take a primary system (septic and trenches); constrained or steep sites, and anything near a waterway, typically need secondary or advanced secondary treatment — usually an AWTS with irrigation.
How do AWTS service reports get to Sunshine Coast Council?
Through council's eServices portal, which processes them instantly — service agents can also post or email them, but council charges an administration fee for hard-copy and emailed reports. Ask your service agent to lodge electronically.
Can I reuse greywater on an unsewered Sunshine Coast property?
Yes, but a greywater treatment plant or diversion device is permit work — it goes through the same Form 1 approval as the rest of your on-site system. See our greywater systems guide for what's involved.
