Keeping Oil Out, Water Moving, and Businesses Flowing.

Oil and water separators play an important role in keeping commercial drainage systems working properly and helping businesses stay compliant with local wastewater requirements. Facilities such as car washes, restaurants, auto shops, parking garages, and industrial properties often collect wastewater that contains grease, oil, sludge, sediment, and other contaminants. Over time, these materials build up inside the separator and can reduce efficiency, create odors, slow drainage, or lead to costly backups.

Professional oil/water separator cleaning removes accumulated oil, grease, solids, and debris so wastewater can flow through the system as intended. Routine service helps prevent clogs, protects downstream drain service, and reduces the risk of contaminants entering the sewer system. For businesses that rely on clean, dependable drainage every day, scheduled separator maintenance is a practical way to avoid disruptions, protect equipment, and keep operations running smoothly.

The Slow Warning Signs Before an Oil/Water Separator Fails

How often should an oil/water separator be cleaned?

Most commercial separators need cleaning every 1 to 3 months, though facilities like car washes or auto shops with heavy oil and sediment loads may need more frequent service. Regular inspection helps determine the right schedule for your specific facility.

What happens if an oil/water separator is not maintained?

Without regular cleaning, oil, grease, and sediment build up until the separator can no longer do its job, letting contaminants pass through into the sewer system. That can lead to slow drainage, odors, backups, and potential compliance issues with local wastewater regulations.
