Grease Trap/Converter

Grease traps and grease converters are essential devices for commercial kitchens, designed to intercept and trap grease, fats, and oils from kitchen wastewater before it enters the drainage system. By capturing these substances, grease traps help prevent damage and clogging of drains, reduce the risk of costly plumbing issues, and ensure compliance with council waste requirements.

Kitchen wastewater flows into the grease trap or converter, where gravity allows fats, oils, and grease to float to the top while solids settle at the bottom. The clarified water then exits the system, while the trapped grease and solids are retained for safe removal and disposal. This process is vital for maintaining efficient kitchen operations and protecting the wider wastewater network.

Regular maintenance is crucial to keep grease traps and converters functioning effectively. Over time, grease and solids accumulate, reducing the device’s capacity and efficiency, and increasing the risk of blockages, odours, and non-compliance with local regulations.

At Dutton Stormwater, we service all types of grease traps and converters across New Zealand—whether you have a small under-bench container in a compact kitchen or a large, fully automatic separator in a busy commercial operation, we can clean them all. Our team inspects, removes accumulated grease and solids, and ensures your system is operating efficiently and in line with council requirements. For underground or hard-to-access units, maintenance may require confined space entry, which is performed by our specially trained technicians following strict safety protocols.

Grease traps and converters typically require maintenance every one to three months, depending on kitchen size, usage, and council requirements. During each service, we assess the system’s condition and includes a job summary with any recommendations in your service report.
