Neighborhood Sewer Problems from Leftover Fats, Oils and Grease

Most people at home don’t produce very much used cooking fats, oils or grease. But we’ve found that even a little grease from the many homes in the City add up to clogged sewers in neighborhoods like yours.

Even if you haven’t needed the plumber to clear your drain, the SFPUC spends millions of dollars each year to unclog the City’s sewer pipes.

Clogged sewers result in unsanitary back-ups, overflows onto streets, foul-smelling odors, and costly damage to sewer infrastructure. So as residents, we are all affected. Fortunately, we can all do something about it.

Plus, we also have chance to produce something useful from our waste, while we’re solving the sewer problem. Your used cooking oil will be recycled to make biodiesel and help power the City fleet on a cleaner-burning renewable fuel.
