Preventing Sewer Overflows

Press Enter to show all options, press Tab go to next option

Fats, oils, and grease generated from residential and commercial cooking processes pose a serious threat to Greensboro's sanitary sewer collection system. These substances cool and solidify, clinging to sewer pipes and restricting the flow of sewage, eventually leading to pipe blockages. Blockages in the sanitary sewer system can cause sewage spills, manhole overflows, or sewage backups in homes and businesses.

Waste fats and oils are frequently poured down the sink drain. Grease also routinely enters the sanitary sewer system as a result of normal kitchen operations, including residential and food service facility washing of dishes, silverware, and pots and pans. Clogged pipes may result in sewer overflows that can cause health hazards, damage home interiors, and threaten the environment.
