ST. LOUIS, MO (KTVI) - You might think of your garbage disposal as the final food processor. It's where the remainder of the meal goes for many. But MSD wants to lift the fog about oils and grease and what you can and cannot put down the drain.
It's clear skies on a Friday morning, but MSD crews are sending their remote controlled robot into a Webster Groves neighborhood looking for fog.
"Fog is: fats, oils and greases," said MSD Spokesperson Sean Hadley. "Like your cooking oils, your salad dressings. A lot of people don't realize that salad dressings does contain vegetable oil which is something that does harm to a sewer system.
That list of no-no's that shouldn't go-go down your drain includes things like gravy, mayonnaise, syrup, batter and even cheese.
"Grease when in a sewer system can act like glue if you will. It can stop up the sewer system either by itself or with debris cause blockages in the pipe. When we have those blockages the result is that water either backs up into basements or our rivers and streams." said MSD Program Manager Jay Hoskins.
MSD says they've seen a 70% reduction in grease related sewer overflows in the last decade thanks to efforts like this. Friday afternoon workers are checking grease traps at restaurants.
The Sweetie Pie's location in Florissant is flowing like it should. But MSD needs some help as the holiday season begins and some extra helpings will be served up.
"When they get those greases off their cooking materials, they need to go in the trash, not down the garbage disposal, not down the sewer system. It's a problem for their pipes, it's a problem for our pipes." said Jay Hoskins.
So the end of the meal should be the beginning of the preventative prep work in your kitchen, and that will help keep robots like this out of your neighborhood.
