Fats, oils and grease can damage sewer lines and potentially cause backups in the sewer system. When discarded down the drain, fats, oils and grease can build up on the interior walls of pipes. When a large amount of buildup occurs, blockage can happen preventing water from flowing through the pipes resulting in a sewage backup (see image.)

Centennial Water conducts routine maintenance of the sewer lines that stretch across its service area. However, we need your help to reduce the risk of fats, oils and grease from causing backups in the lines.

Wipe. Remove grease from pots, pans and dishes with a scraper or paper towel and discard it in the trash.

Pour. Discard cooking oil or grease in a secure container. Use a metal can to collect the grease such as a coffee can, vegetable or soup can.

Trash. Put all cooled, discarded cooking oil or grease in the trash.

Examples of fats, oils and grease:

• Cooking oil
• Butter
• Salad dressing
• Gravy
• Mayonnaise
• Sauces
• Shortening
