02/14/2008: "DOE: Put Drain Pipes On A Fat-Free Diet"

It’s not something we think about when we pour leftover grease down the drain, but health departments -wastewater treatment plant operators- across the state wish folks would put their pipes on a fat-free diet.

The Department of Ecology (DOE) points out that most blockages in septic and sewer systems can be traced to the presence of fats, oils, and grease, creating sewage spills and sewage overflows both onto private property and into city streets. It can also mean more frequent pumping of septic tanks; and that means more expense to the home owner..

“Cleanups are difficult and costly,” explained Lynda Jamison, a water-quality specialist with the Washington Department of Ecology. “Blockages can cause raw sewage to back up into streets and possibly even into homes and businesses.”

Many home owners believe that pouring grease down the drain and following it with lots of hot water will keep the fats liquefied and carry them safely through the pipes. This is not true. Fats, oils, and grease cool down very quickly and can solidify after traveling only a few feet.

Raw sewage in the pipes will attach to fats, oils, and grease, creating impenetrable globs that back up drain lines. These globs of fat and waste are difficult to disinfect at treatment plants and can allow disease-causing pathogens to enter nearby streams, lakes, and rivers.

Home owners can help keep fats from clogging pipes by disposing grease properly

• Never pour fats, oils, or grease down the drain.
• Never flush fats, oils, or grease down the toilet.
• Always put grease in the trash.

Pour hot oils or grease into heat-proof containers, such as a tin can, and cool before putting it in the trash. You may even freeze the grease for easier disposal. Wipe greasy pans and dishes with paper towels before washing them and throw the paper towels into the trash to keep as much grease as possible out of your drains.

DOE says hese tips can help prevent expensive plumbing repairs and sewage overflows. You can save yourself some repair bills, and keep our rivers and streams clean when your pipes on a fat-free diet. Dispose of grease properly.
