Keep fats oils and grease out of your pipes this holiday season! Excess fats, oils, and grease (FOG) may result from preparing food and should never be poured down the sink, or flushed down the toilet. FOG that's poured into the sink or toilet will harden in the pipes causing backups in your plumbing and Boston's sewer system. Always dispose of FOG into the trash. BWSC encourages you to Can The Grease! After cooking, let FOG cool in the pan. Once cooled, pour or scoop FOG into a can, cover the can with a BWSC Grease Lid and store it in the freezer until full and dispose of the can on your regular trash collection day. Boston residents can request a FREE BWSC Grease Lid! Call BWSC at 617-989-7599, or request one online at www.bwsc.org.
