Customer reviews
I have been a plumber for over thirty years and installed many water treatment systems. CleanaWater systems are by far the best for quality and reliability. They provide excellent customer service, from sales staff right through to expert advice and technical help. Can't thank CleanaWater enough!
Iain Paterson, Multilple Trades and Maintenance
We have seen a fantastic improvement since the OdourPro VapourGard™ system was installed 3 years ago. The system mitigates the heavy odours which are released from the site, which has improved conditions for our staff and almost completely eliminated complaints from local residents and businesses
Glenn Claverie, Select Civil
The whole process was very simple, the sales and technical support was great, when needed contact was made easily for assistance during construction and the finished product works and looks fantastic, all in all working with the CleanaWater team to purchase our new Portable Wash Bay was a trouble free process
Doug Neil, Stihl Sales and Service Centre Coffs Harbour
The purchasing of our oil separator, from obtaining a quote through to delivery, was made extremely easy through CleanaWater, the staff are easy to deal with and make the whole process hassle-free, as well as supplying a quality product. I would highly recommend CleanaWater products in the future.
Bret Sheehan, Surefire Plumbing Services
The VapourGard™ system is a great alternative to the other odour suppression systems out there. The unit is easy to use and maintain, does not need a portable water source to dilute the chemical and has a low chemical usage which cuts down on cost.
Nicholas Bhugon, SITA Australia
Cleanawater have been very helpful in getting the solution ordered and out the door to us as quickly as possible. All this in the midst of supply chain issues globally. It’s nice when things still, just, work!
Tom Filipcic, FUCHS Lubricants (Australasia) Pty. Ltd.
In combination with a wide range of operational controls, we have found that complaints from our neighbours have significantly reduced since the VapourGard was installed.

Frequently asked questions
How do I know if my portable wash bay is compliant with local water authority regulations?
To ensure compliance with local water regulations, your portable wash bay floor should be equipped with essential features such as bunding, water holding channels, and pre-treatment devices and diversions systems. These elements help prevent contaminated water from entering stormwater systems. If you’re unsure whether your current setup meets regulations, contact Cleanawater for a water treatment consultation and get expert advice tailored to your location and industry requirements.
How do I best retain solids that accumulate in my portable wash bay?
Managing solids is crucial to keeping your portable wash bay running efficiently. Installing silt traps and baffled pits allows for easy removal of solids like dirt and debris. For environments with heavy solids accumulation, beach pits and drive-in sumps are highly effective solutions that simplify maintenance and prolong the lifespan of your wash bay system.
How do I best retain solids that accumulate in my portable wash bay?
Yes, wastewater produced by portable wash bay needs to be pre-treated before it enters local wastewater systems. Discharging without treatment is against the law, and can result in heavy fines for businesses.
First flush diversion systems attached to unroofed, portable wash down bays larger than 20sqm can treat any run-off before it enters stormwater drains.
Can I still install a portable wash down bay if I have no access to sewerage on-site?
Yes, even without access to a sewerage system, there are several discharge options available. These include leach drains, evaporative ponds, and holding tanks, which are designed to safely manage wastewater. If your site uses a septic system or is in a remote area, it's essential to consult your local council for guidelines on treated wash water disposal to ensure compliance with regional standards.
Water recycling systems are another excellent solution is a sewer connection is not available.
Does portable wash bay equipment change depending on the industry?
While the core components of portable wash bays are similar across industries, specific industries may require additional features. For example, businesses dealing with chemicals or highly acidic wastewater may need pH correction systems. For advice on customising your wash bay setup beyond an oil water separator or diversion system, call Cleanawater to discuss the entire process.
What types of portable wash bays are available for different vehicles?
Cleanawater offers a variety of portable wash bays designed to cater to specific vehicle types and industries. Whether you're looking for portable truck wash bays for heavy-duty equipment, portable motorcycle wash bays for smaller-scale operations, or wash bays for cars and machinery, we have tailored solutions to meet your needs. Each wash bay is equipped with advanced water treatment systems and can be customised to ensure compliance with local environmental regulations.
