Why a Trime Wash Bay is a Must-Have in New Zealand

In New Zealand, businesses must strictly comply to rules when it comes to the environment. The Resource Management Act makes it a no-go for things like oil, grease, and chemicals to end up in our waterways, including our stormwater systems. If you run a business that needs to wash down equipment, you’ll know it can be a headache making sure you’re compliant.
That’s where the Trime Wash Bay comes in. It’s a self-contained system that captures and recycles water, making it a smart way to meet environmental regulations and keep your gear clean at the same time.
The Pollution Problem
Wash water from cleaning machinery can contain all sorts of pollutants—dirt, oil, fuel, and detergents, to name a few. When this water runs down a drain and into a local stream or the ocean, it can harm the environment. Councils can hit you with a fine for breaching the rules, so having a proper wash facility on-site is a must for any business that regularly cleans its equipment.
A Smart Solution for Your Site

The Trime Wash Bay is designed to be a responsible, all-in-one solution for companies in industries like construction, hire firms, and local councils. Here's how it keeps you compliant:
- It's a Closed System: The wash bay is designed to contain all the water and overspray, stopping any oil, grease, or other nasties from reaching the surrounding environment or local drains.
- Water Recycling: It's a closed-loop system, so it recycles water through a series of filters, helping to reduce your overall water use.
- The Filtration Process: Dirty water runs into a solids collection tank and then through various chambers, including sand traps and hydrocarbon mats. This process gets rid of sediments, oils, and other contaminants. A booster pump then sends the clean, filtered water back to your pressure washer, ready to be used again.
By using a Trime Wash Bay, you’re not just cleaning your equipment; you’re also helping to protect New Zealand’s environment and avoid costly fines.
Flexibility and Logistics
One of the major upsides of the Trime Wash Bay is its modular design, which solves a lot of logistical issues on busy worksites or leased yards:
- Easy to Relocate: The wash bay's simple construction means it's easy to assemble and disassemble for quick transport. If you move your yard or have a temporary project site, the wash bay can move with you, ensuring continuous compliance without losing your investment.
- Simple Setup: These systems are designed to be an above-ground, self-contained solution. This often eliminates the need for expensive and disruptive civil works or in-ground services.
- Reduced Permitting Issues: Since the system is generally considered a relocatable piece of equipment and doesn't require permanent plumbing alterations, it can often simplify or bypass the need for extensive building consents. However, you may still need a Trade Waste Consent from your local council if you plan to discharge any wastewater into the public sewer system.
This flexibility means you can deploy a compliant wash solution exactly where and when you need it, avoiding the 'sunk cost' of building permanent infrastructure.
