Rural Septic Systems New Zealand
Rural septic tanks for hassle-free installs
Rural septic jobs can look simple on paper, then access and logistics chew up the day. You need a tank option that’s easier to handle on site, practical to transport, and straightforward to hand over.
Ozzi Kleen gives you rural septic tank options supplied in New Zealand through DrainPro, with clear specs and support when you need it.
When access is tight, lighter handling matters
On rural sites, delays usually come from access, lifting, and the extra coordination around getting the tank in place. You’re protecting your time and your margin, and you want a smooth run from dig to backfill.
With Ozzi Kleen’s lightweight poly tank options, you can often keep the workflow simpler on sites where a Hiab is awkward or not always necessary.
What makes Ozzi Kleen easier for rural installs?
These are practical reasons tradies choose it, because they show up on site.
Lightweight poly construction, so handling and placement are simpler than many concrete alternatives
Digger-friendly placement on many sites, depending on access and your lift plan
Single-piece tank construction to reduce join-related issues
15-year tank warranty for long-term confidence
NZ supply and support through DrainPro, so you can get guidance and parts without long delays
Your installation approach depends on the model, site access, ground conditions, and the design for the property.
Built for rural conditions
You want fewer surprises once it’s buried, and an owner who understands what they’ve got.
You get a practical tank option designed for buried installation, backed by:
durable poly construction
simple access for inspection and servicing as required
a straightforward handover story for rural owners
If the site has high groundwater, saturation, or tricky soils, the disposal field and design matter just as much as the tank. If you share the site basics early, you can confirm what’s appropriate before you lock in the quote.
