FAQ about Cooking Oil, Grease Disposal and Recycling
(from Texas Commission on Environmental Quality)
Why shouldn't I pour used cooking oil down the drain?
Cooking oil and grease poured down drains can build up in pipes causing backups at home, into streets and the storm drain system. Proper disposal of your cooking oil and other greases and fats will help prevent a sewage backup in your home. Overflows can pose health and environmental hazards, polluting local creeks and rivers.
What about using my garbage disposal, hot water or detergent to wash grease down the drain?
These methods won’t prevent grease from building up in sewer pipes. Home garbage disposals do not remove grease from the plumbing system. Hot water will cool down in pipes causing fats and grease to coagulate. Detergents that claim to dissolve grease may cause blockages to occur further down the pipeline.
