Tank, Drain and Oil/Water Separator Cleaning

If your tank or sump contains hazardous waste or spilled hazardous material, you'll need to dispose of it as hazardous waste. You may also need to notify the Department of Ecology at 425-649-7000 and comply with hazardous waste tank regulations. Non-hazardous wastewater can be transported without a hazardous waste manifest. If sludge has accumulated in the bottom of the tank or sump, a vacuum truck will be needed to remove it. For liquids with little or no sludge, a pump may be adequate. You may still want to keep receipts for your records. Call a tank cleaning service to test and/or determine what's in your tank.
