They go beyond the functionalities of interceptors and oil separators, and provide all-encompassing, permanent solutions for washing vehicles and equipment. Constructed with durable concrete and materials , these wash bays provide a sturdy foundation that meets stringent regulatory requirements while supporting high-volume washing needs.

Fixed wash bay designs
Permanent wash bays provide an eco-friendly and cost-effective option for keeping your vehicles, machinery or other equipment clean. Save time and money with these long-lasting self-contained washing bays. Our bays protect the environment from potentially harmful wastewater.
Built-in interceptors and oil-water separators capture contaminants, keeping wastewater compliant with environmental regulations. Sloped floors guide runoff to designated drains, reducing standing water and enhancing safety. Additionally, with features like adjustable platforms and high-pressure water systems, fixed wash bays provide a practical and low-maintenance solution for various vehicle cleaning needs.

Frequently asked questions
How do I know if my permanent wash down bay complies with local water authorities?
If you have a permanent wash bay already installed at your worksite and you’re unsure if it meets local regulations, contact us today. We'd be happy to get you up to speed and advise on any changes you need to make.
Unroofed, permanent wash bays should prevent untreatedrunoff from entering stormwater drains. They are required by law to have various features, including a holding pit, bunding, diversions systems, and pre-treatment devices. We’ll assess your wash bay area to ensure it meets all requirements.
What's the best way to retain solids from permanent wash bays?
Cleanawater has a range of solutions to separate solids for easy removal from wastewater. Drive-in sumps and beach pits are ideal for permanent wash down solutions that carry a high amount of solids. These components help permanent wash bays collect solids and discharge treated wash water into the environment - making the whole process cleaner and safer.
Do I need any equipment to treat water from permanent wash down bays?
As a rule of thumb, you cannot allow wastewater from permanent wash down bays to discharge directly into wastewater systems. If you have an unroofed permanent wash bay that is larger than 20sqm, you will require a first flush diversion system or similar pre-treatment device.
Can I still install a permanent wash down bay if I don't have sewerage on-site?
You can. Businesses without access to sewerage can use a range of discharge methods approved by local water authorities. These include holding tanks, evaporative ponds, and leach drains.
Businesses located in regional areas may have septic systems. If this is you, contact your local council for accurate advice on where to discharge your treated water.
Do permanent wash bays change equipment depending on the industry?
Yes, permanent wash bays can be customised with different equipment to suit the specific needs of various industries. For example, wash bays for the automotive industry may include high-pressure water systems and brushes for thorough vehicle cleaning, while those designed for construction or mining operations might have heavy-duty mud removal systems and stronger drainage setups.
Industries with stricter environmental standards can integrate advanced oil-water separators and filtration systems. This flexibility in equipment ensures that each wash bay meets the unique cleaning and regulatory requirements of its intended industry.
Can a permanent wash bay be installed in an existing facility?
Yes, a permanent wash bay system can be designed to integrate with existing site infrastructure. This allows businesses to add a compliant wash area without needing to completely overhaul their current operations.
