It's important to keep fats, oils, and grease (F.O.G.) out of drain pipes to avoid backups and costly repairs. Here is how to dispose of F.O.G.: First, let fats, oils, and/or grease solidify. Then, place solidified F.O.G. into bagged household garbage.
Have a large amount of F.O.G.? Funnel used F.O.G. liquid into a disposable container (i.e. a gallon milk jug) and then, once solidified, place the entire container into the garbage. This is a particularly useful method after frying a turkey around the holidays.
New Braunfels Utilities has more information on F.O.G. on their website.
