Prevent Sewer Blockages

Residential FOG

Grease gets into sewers from household drains, as well as from poorly maintained grease traps in restaurants and other businesses. Pipelines blocked by grease can cause major problems such as:

  • Raw sewage backing up into your home or your neighbor’s home
  • Expensive and unpleasant clean-up that, often, you must pay for
  • Raw sewage overflowing into parks, yards, and streets
  • Potential contact with disease-causing organisms from the sewage overflow
  • An increase in operation and maintenance costs for BCWS, which could cause higher sewer bills for you

Grease from cooking—meat fats, lard, oil, shortening, butter, margarine, food scraps, baking goods, sauces, and dairy products— should NEVER be put down any drain.

Why not?
When washed down the sink, grease sticks to the inside of the sewer pipes on your property and the pipelines in the street. Over time, it can build up, harden into a plug, and block an entire pipe, causing sewer overflows and backups.

Is it okay to put it down my garbage disposal or use detergent to wash it down the drain?
NO! That will not prevent grease from building up. Home garbage disposals do not keep grease out of the plumbing system. Products such as detergents that claim to dissolve grease may pass the grease down the pipeline and cause problems elsewhere.

What can I do?

  • Scrape grease and food scraps into a can or the trash for disposal (or recycling where available).
  • Whenever you have a greasy pan to wash, wipe it out after use (while it’s still warm, not hot) with newspaper or paper towel.
  • Put baskets/strainers in sink drains to catch food scraps and other solids, and then empty them in the trash.
  • Encourage your friends and neighbors to keep grease out of drains.
