Fats, Oils and Grease (FOG)

No Grease Down the Drain

Grease-clogged sewer pipe

grease can completely block sewer pipes

Grease is a byproduct of cooking. It comes from meat, lard, oil, shortening, butter, margarine, food scraps, baking goods, sauces and dairy products.

 

When grease washes down the sink, it sticks to the insides of the pipes that connect your home or business to the city's sewer. It also coats the insides of the city's sewer pipes.

 

Eventually, the grease can build up until it completely blocks sewer pipes. That can create difficult and expensive maintenance problems for both the city and private property owners.

 

Blocked sewer pipes can cause raw sewage to back up into your home or business, or overflow into streets and streams.

 

Garbage disposals don't keep grease out of sewer pipes. Products that claim to dissolve grease may dislodge a blockage, but will only cause problems farther on down the line when the grease hardens again.
