What Somerset asks for
Somerset takes in Esk, Kilcoy, Fernvale, Lowood, Toogoolawah and a lot of unsewered acreage between them, and its plumbing services page sets out the process plainly: lodge the correct application form (the state Form 1, from the Queensland Government forms library), plans and reports, and the fee, at a customer service centre or by email. Council applies the standard 10-business-day assessment period under section 45 of the Plumbing and Drainage Regulation 2019, starting only once every required document and the fee are in.
The distinctly Somerset part is water supply catchments. The council area wraps around Wivenhoe and Somerset Dams — South East Queensland's drinking water — so properties near the Brisbane River or in the Wivenhoe, Somerset or Atkinson Dam catchments need a referral to Seqwater, with its pre-approval in hand before council will take the application. Build that extra step into your timeline.
- Form 1 with drawings drafted by an accredited on-site sewerage designer, plus the site and soil evaluation
- Progressive inspections: under-slab drainage, drainage rough-in, water rough-in and final — booked on 24 hours' notice on (07) 5424 4000, quoting your permit number
- Treatment plants must hold a current state treatment plant approval and be serviced quarterly, per the statewide rules
Council points to its Building, Plumbing and Drainage fees document for current charges rather than publishing a single OSSF figure; budget within the state-typical range on our QLD approvals guide and confirm the exact fee with the plumbing officers when you lodge.

Fees change each July and the Seqwater referral requirement depends on your exact location — check both with Somerset Regional Council on (07) 5424 4000 before lodging.

Common questions
Why does Seqwater get a say in my septic application?
Because much of Somerset drains into South East Queensland's drinking water storages. Council requires properties near the Brisbane River or in the Wivenhoe, Somerset or Atkinson Dam catchments to obtain Seqwater referral and pre-approval before the plumbing application is lodged.
How long does Somerset take to assess a septic application?
Council applies the standard 10-business-day assessment period under the Plumbing and Drainage Regulation 2019 — but the clock only starts when every required document and the fee are received, and any Seqwater referral happens before that.
What inspections will council do during the install?
Somerset inspects progressively: under-slab drainage, drainage rough-in, water rough-in and a final inspection. Your plumber books each one with 24 hours' notice, quoting the permit number. Nothing gets backfilled until the inspector has seen it.
