Oil Water Separator Cleaning Services in Chicago & McHenry County

Oil, fuel, sludge, and contaminated wash water can create major problems for commercial facilities if they enter the sewer system untreated. Without proper maintenance, an overloaded separator can lead to backups, environmental violations, expensive repairs, and failed inspections.

At A&J Sewer Service, we provide professional oil water separator cleaning services for businesses throughout Chicago, Crystal Lake, McHenry County, and surrounding communities. Our experienced team helps commercial properties maintain clean, compliant, and efficient wastewater systems with reliable service and thorough inspections.

Whether you operate an automotive facility, dealership, fleet garage, or industrial property, we have the equipment and experience to keep your separator system operating properly.

What Is an Oil Water Separator?

An oil water separator is a specialized wastewater treatment system designed to prevent oils, fuels, grease, and automotive fluids from entering municipal sewer systems or local waterways.

Many people wonder how it is possible to separate oil and water. The answer comes down to density. Oil naturally floats while heavier solids sink. Inside the separator, oils rise to the surface, sediment settles at the bottom, and cleaner water flows through the middle before entering the drainage system.

An oil water separator tank plays an important role in protecting both sewer infrastructure and the environment. Businesses that work with vehicles, machinery, or industrial fluids commonly install these systems to prevent contamination from entering the sewer system.

Businesses That Commonly Use Oil Water Separators

Many commercial and industrial facilities rely on separator systems every day, including:

  • Auto dealerships with service bays
  • Automotive repair shops
  • Fleet maintenance facilities
  • Trucking depots
  • Car rental service centers
  • Parking garages
  • Municipal maintenance yards
  • Industrial wash-down facilities

If your property handles motor oils, fuel, or vehicle fluids near floor drains, routine oil water separator maintenance is essential.

Thorough Oil Water Separator Cleaning

Over time, sludge, oil, grit, and debris collect inside the separator tank. As buildup increases, the system loses efficiency and may stop separating contaminants properly.

Once the separator reaches capacity, untreated wastewater can bypass the system entirely. This creates serious environmental concerns and may lead to regulatory violations or expensive cleanup costs.

Our oil water separator cleaning services include:

  • Complete pumping of the separator tank
  • Removal of sludge, oils, and sediment
  • Cleaning of interior surfaces
  • Inspection of baffles and components
  • Verification of inlet and outlet flow
  • Identification of damage or wear

Routine cleaning keeps your system operating efficiently while helping you avoid unexpected disruptions.

Called for a septic clean out. Bob was there in 30 minutes with truck, ready to do the job. Bob was great. Fast and Professional. Don't waste time with anyone else. Others will take days and cost 2 times as much. Call A&J first.

A & J took the time to explain our catch basin and drain system to really help us feel more educated about what we are dealing with. They gave us some ideas that were not even part of their services and also rodded out our drain lines and supplied a video showing them crystal clear. I would recommend them to any homeowner in need of drain or septic service.

What Does Oil Water Separator Maintenance Involve?

Proper oil water separator maintenance involves more than simply pumping out waste. Regular inspections and preventive care help extend the lifespan of the equipment and reduce the risk of costly failures.

During maintenance visits, our team checks:

  • Oil and sludge levels
  • Structural condition of the tank
  • Baffles and separator components
  • Inlet and outlet connections
  • Signs of corrosion or deterioration
  • Drainage flow performance

By identifying problems early, we help businesses avoid emergency repairs and operational downtime.
