Septic Tanks Lismore Northern Rivers NSW # Septic Tanks Lismore — Delivered Across the Northern Rivers Lismore sits on the Wilsons River in the heart of the Northern Rivers and is one of the highest-enquiry areas we service. Most blocks outside the CBD are unsewered, run on conventional septic, and sit on the region's well-known heavy clay soils — which makes tank choice and absorption-trench sizing both important. [Enquire about Lismore delivery](/contact)[View both tanks](/products) ## Which tank for Lismore? Tank Best for From 1500L poly 2–4 person dwelling, granny flat, cabin, tiny home $949 2500L three-chamber 4–6 person home, farmhouse, larger household [View pricing](/product/2500l-septic-tank) ## Local context — Lismore Lismore's hinterland is dominated by deep red and brown clay loams over basalt. Clay holds water, which means absorption trenches typically need to be longer than the textbook minimum to handle effluent in wet months. Your licensed plumber will run a percolation test and size the trench accordingly — the tank itself stays standard. Flood-affected lowland blocks (post-2022) often need the tank sited on the higher ground of the lot, with access risers brought up well clear of any expected flood level. ## Delivery to Lismore We deliver poly septic tanks across the Northern Rivers from our depot, typically 3–10 working days after order. Pickup is available where practical and is the cheapest option. ## Council and approvals Septic approvals in Lismore are processed by **Lismore City Council** under the NSW on-site sewage management framework. Your licensed plumber lodges the paperwork as part of the install — see our [council approval guide](/do-i-need-council-approval-septic-tank) for the full process. ## Frequently asked questions — Lismore ### Do you deliver septic tanks to Lismore? Yes. We deliver 1500L and 2500L polyethylene septic tanks to Lismore 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 Lismore? For most Lismore-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 Lismore? Lismore City Council processes on-site sewage management approvals for Lismore. 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 Lismore? 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. ### Do Lismore's clay soils affect what septic tank I should buy? Not the tank — clay affects the absorption trench, not the tank itself. You still install a standard 1500L or 2500L poly tank. Your licensed plumber sizes the trench longer to handle slower percolation through clay. If your block is flood-affected, you may also need to site the tank on higher ground with extended access risers. ## Nearby towns we also service We deliver septic tanks across the Northern Rivers NSW — including: - Goonellabah - Nimbin - Bexhill - Clunes - Dunoon Don't see your town?
