As well as causing problems at home, fats can also clog up the main sewer pipes under the street that take your used water away. Once clogged, the wastewater has nowhere to go but out of a manhole or clean-out in the street or sidewalk. The result is a greasy, smelly mess of pollutants that has the potential to enter storm drains, creeks, and the Russian River. It harms wildlife both on land and in water and is expensive to clean up.
