Local context — Tweed Heads
Tweed hinterland blocks frequently sit at the end of long, winding driveways with grade or width that defeats a HIAB truck. That's where poly's 61 kg (1500L) or 110 kg (2500L) tank weight becomes the practical advantage — a standard ute reaches sites a 1,500 kg concrete delivery can't. Tweed Shire processes septic approvals through its on-site sewage management programme; your licensed plumber lodges the paperwork as part of the install.

Frequently asked questions — Tweed Heads
Do you deliver septic tanks to Tweed Heads?
Yes. We deliver 1500L and 2500L polyethylene septic tanks to Tweed Heads and across Northern Rivers NSW. Lead time is typically 3–10 working days from order. Pickup from our depot is also available and is the cheapest option where it's practical for you.
What size septic tank do I need in Tweed Heads?
For most Tweed Heads-area households, a 1500L tank covers a 2–4 person home. Larger households (4+ permanent occupants), farmhouses or homes with a second dwelling typically step up to a 2500L three-chamber tank. Where there's a separate granny flat or workers' cottage, a dedicated 1500L tank for that dwelling is usually simpler than oversizing one shared tank.
Which council handles septic approvals in Tweed Heads?
Tweed Shire Council processes on-site sewage management approvals for Tweed Heads. Your licensed plumber lodges the Notice of Work before install and the Notice of Completion afterwards — that paperwork is part of every legitimate septic install, regardless of which tank brand you buy.
How much does septic installation cost in Tweed Heads?
All-in install in the Northern Rivers NSW region typically runs $5,500–$9,500 for a 1500L poly system (tank, sand bedding, excavation, plumber connections, absorption trench, council fees). Concrete equivalents typically add $2,000–$4,000 on top, mostly in freight and crane costs. See our full cost breakdown for a line-by-line picture.
Can you deliver to steep hinterland blocks around Tweed?
Yes — that's exactly why most hinterland owners choose poly. We've delivered to blocks where concrete simply can't go because the access track is too narrow or too steep for a HIAB truck. A poly tank rides on a standard ute and can be carried into position by two people.
