What Tweed asks for
Tweed follows the standard NSW two-approval structure, documented on council's on-site sewage management page and a practical series of fact sheets covering septic tank and absorption trench systems, reed beds, AWTS and greywater arrangements. The install approval comes first, with plans and a wastewater assessment; a licensed plumber-drainer does the work; and the approval to operate follows, based on an application describing how the system will be operated, maintained, serviced — and what happens when it breaks down.
- s68 application to install or alter, with site plan and wastewater assessment; installation by a licensed plumber/drainage contractor
- Approval to operate: $126 application covering up to two systems ($63 per additional system) on the 2025–26 schedule
- Annual operate renewal of $69, which funds council's ongoing oversight of the shire's systems
Tweed's coastal floodplain and cane country add practical constraints: high groundwater, flood-prone land and estuary catchments mean absorption trenches don't suit every block, and the fact sheets steer constrained sites toward reed beds, mounds or aerated systems with irrigation. AWTS owners carry the usual quarterly servicing condition, with reports going to council — factor it into running costs before you choose a system.

Common questions
What does the approval to operate cost in Tweed?
On the 2025–26 schedule: $126 for the initial application covering up to two systems, $63 for each additional system, and a $69 annual renewal. The install approval fee is separate — check council's current fees & charges.
Will an absorption trench work on a Tweed floodplain block?
Often not — high groundwater and flood-prone land rule out conventional trenches on many lowland blocks. Council's fact sheets cover alternatives like reed beds and aerated systems with irrigation; your wastewater assessment will confirm what the site supports. Compare system types first.
Who has to install the system?
A licensed plumber or drainage contractor — council requires it, and the operate approval application must describe how the system will be maintained and serviced and what happens in a breakdown.
