Commercial Wastewater Treatment Systems

Predictable Systems for Faster Installations

Commercial jobs move faster when the treatment side is predictable. You get the right system type and sizing support, so you can commission sooner, avoid scope gaps, and hand over a site that runs reliably.

If you’re comparing options for commercial sites in New Zealand, start here.

What makes Ozzi Kleen practical on commercial jobs

Pre-engineered system packages

Packaged, pre-engineered systems mean you’re not redesigning or re-specifying from scratch on every commercial job.
 

Predictable plug-and-play setup

A plug-and-play approach on many sites makes installation and commissioning more consistent and easier to plan.
 

Cyclic control for variable loads

The cyclic control process helps the system handle fluctuating flows and peak demand without manual intervention.
 

Flexible installation formats

Transportable and permanent system options let you match the solution to the site conditions and project timeframe.
 

Designed for future capacity

Capacity planning allows you to size correctly now while accommodating future expansion if required.
 

Local NZ supply and support

DrainPro provides New Zealand-based supply, documentation, and practical guidance through installation and handover.
 

When the treatment side drags, your whole job drags

It’s frustrating when you’re ready to move, but the treatment plant becomes the thing holding up the project. You’re trying to protect your timeline, avoid rework, and hand over something the site can run without constant babysitting.

You get help through DrainPro to choose the right category, size it with confidence, and keep the job moving.

What you get when you enquire

You shouldn’t have to chase basics just to scope the job properly.

When you request specs and sizing help, you can get:

The right category recommendation (transportable versus permanent)

Sizing guidance based on expected load and peak periods

Documentation to support quoting and planning

Pricing and lead time guidance

Your next step

You don’t need a long back-and-forth to work out if this fits. You stay on programme, and you hand over a system the site can run reliably.

1

Send the site basics

Location, expected occupancy, peak periods, and whether the site is temporary or permanent.

2

Get a recommended system type and sizing

So your scope and quote are built on the right assumptions.

3

Confirm inclusions, pricing, and delivery plan

Then you can place an order request when the project is ready.

Your questions answered

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.

Is this the same as a septic tank?

Not always. Many commercial sites need a treatment plant approach rather than a basic septic option. If you’re comparing commercial plants with septic tank systems New Zealand suppliers offer, start with occupancy and peak flow. That usually makes the right category obvious.

What does PLC control mean on site?

A programmable logic controller (PLC) runs the treatment cycles automatically. For you, that usually means more consistent operation and clearer fault finding if something goes wrong.

Can you make capacity bigger later?

Often, yes but it needs to be planned properly at the start. If expansion is likely, flag it early so sizing and configuration can allow for growth.
