4. My sewer line is backed up what should I do?

The most likely cause is a line blockage in your service line caused by grease, hair and other debris. Property owners are responsible for clearing these types of line blockages from the house to the mainline in the street, therefore you should contact a plumber to assist you. If you (or your plumbing contractor) suspect that there is a broken pipe in the line between the property line cleanout and the mainline or a blockage in the mainline, then you should contact the County Wastewater Collections Department at 243-7465.
