Otobai Wholesalers

Background to the challenge

Founded in 1993 in Queensland, Otobai Wholesalers is an automotive workshop specialising in motorcycle repair, import and wholesale.

Otobai boasts access to all motorcycle makes, models and parts, the majority of which come from Japan and the USA. It's why Otobai supply and service an enviable number of motorcycle dealerships across Australia.

The problem

Following its 2007 relocation to North Melbourne, Otobai needed to build a new wash bay that adhered to strict AQIS (Australian Quarantine Inspection Service) requirements.

In particular, wash-down water would need to be treated to an acceptable level before it was discharged to sewers. Otobai needed a cost-effective solution that would bring their wash bay up to these requirements – ensuring they avoided costly fines and shutdowns.

For a solution, Otobai Wholesalers approached Cleanawater.

What Cleanawater did

Calling on decades of expertise in AQIS regulations, we recommended a pre-treatment device to treat wash-down water prior to discharge to sewer.

The ideal solution would be an oil water separator and non-emulsifying pump working in unison. So we installed our TS 1500 SS oil water separator – complete with 100-micron filters. A non-emulsifying pump was then put in place to effectively direct the treated water to sewer. The entire system was installed in a single day, meaning no disruption to Otobai's business

The result was a wash bay that exceeds AQIS and trade waste standards – a low-maintenance, low-cost water treatment solution that meant zero fines or shutdowns.
