Keep grease out of the sewers. Dispose of greasy and fatty foods, such as salad dressings, cooking oil, ice cream, and sauces, in your garbage can instead of your sink or garbage disposal. Direct your gutters to send water away from house foundations. Make sure there are strainers over all floor and sink drains in your home. Have the line that connects your house with the public sewer line (called a house lateral or private sewer line) inspected.
Repairing broken private sewer lines, which is the homeowner's responsibility, can keep stormwater from leaking into pipes and prevent sewer backups in your home.
