Oil Separator

An oil separator is a device designed to trap, remove, or separate oil, grease, fuel, and sediment from wastewater in industrial settings. By capturing these contaminants before they enter the drainage system or waterway, oil separators help ensure compliance with regulations and support sustainable environmental practices. You’ll commonly find oil separators at workshops, service stations, manufacturing facilities, and other sites where oily wastewater is generated.

Wastewater flows into the oil separator, where gravity and a multi-chambered design allow heavier sediments to settle at the bottom and lighter oils, grease, and fuels to rise to the top. The clarified water exits the system, while collected oil and solids are retained for safe removal and disposal.

Regular maintenance is essential to keep oil separators functioning effectively. Over time, oil, grease, and sediment build up in the chambers, reducing treatment efficiency and increasing the risk of blockages, flooding, or non-compliance with council and environmental requirements.

At Dutton Stormwater, we provide comprehensive oil separator maintenance services across New Zealand. Our team inspects, removes accumulated oil and solids, and ensures your separator is operating efficiently and in line with environmental standards.

Oil separators typically require maintenance every six to twelve months, depending on site activity and pollutant loading. During each service, we assess the separator’s condition and includes a job summary with any recommendations in your service report.
