Household Aerated Treatment Systems
Aerated wastewater treatment when septic isn’t enough
When a standard septic set-up won’t suit the site or council requirements, you need an aerated system you can specify clearly, install confidently, and hand over without second-guessing.
If you’re looking for Aerated Wastewater Treatment that New Zealand projects can rely on, Ozzi Kleen gives you a practical option backed by local support through DrainPro.
Heading about section
This is a short section of centred text as a rest break on the eyes from more photographic stacks. It would be best to be kept to not more than about four lines of text, as research shows long sections of text can become cumbersome to read without a tidy left margin.
When the site needs more than a basic septic tank
It’s frustrating when you’re quoting a job and the treatment requirement isn’t straightforward. You’re balancing site constraints, expected load, consenting, and the risk of call-backs if the system isn’t matched properly.
You get support to choose the right category and confirm the fit early, so your install stays on track.
What you get with Ozzi Kleen aerated treatment
You’re not just choosing a product. You’re choosing how smooth the install and handover will be.
Cleaner treatment outcomes than a basic septic tank for sites that need a higher level of treatment
A system designed for changing loads and peak periods, so the site isn’t relying on perfect conditions every day
A clearer path to specifying and documentation, so your scope and handover are easier to explain
Support through DrainPro in New Zealand, so you can get guidance and next steps without long delays
Where aerated sewage treatment is a strong fit
You’ll typically look at local New Zealand Aerated Sewage Treatment projects when the site needs higher treatment performance than a standard septic approach.
It’s often a better fit when:
The site is sensitive or has tighter discharge requirements
Occupancy and flow rates vary (events, peak seasons, staff accommodation, shared facilities)
You want a cleaner handover story for owners and operators
You need a system that’s easier to manage long-term than a basic septic set-up
Final suitability depends on correct design, installation, and local requirements. If you share the site basics, you can confirm fit early.

Your questions answered
Is aerated treatment always required?
Not always. It depends on the site, disposal design, and local requirements. If you’re unsure, start with the site basics and you can confirm the right category quickly.
What’s the difference between a septic tank and an aerated wastewater treatment plant?
A septic tank provides basic primary treatment, while an aerated wastewater treatment plant uses oxygen to support a higher level of biological treatment and typically produces a cleaner effluent for disposal as designed.
What do you need from me to recommend a system?
Site location, estimated occupancy range, peak periods, and any known discharge/disposal requirements. If kitchens, laundries, or higher loads are involved, include that too.
Will this meet NZ requirements?
Your outcome depends on correct design, installation, and local requirements. If you request specs and sizing help, you can make sure you’re selecting the right option for the site from the start.
What you gain
You get a clearer pathway from quote to install, fewer avoidable surprises during consenting and handover, and a system choice you can stand behind.
