May used antifreeze be put down drains?
Although it's possible to receive permission from your local publicly owned treatment works ( POTW) to sewer used antifreeze, due to the heavy levels of lead and other metals it commonly contains, discharging down drains is NOT recommended as a best management practice.
HOW TO DISPOSE OF ANTIFREEZE
IF YOU DO NOT HAVE A SEPTIC TANK, and your drain is a connected to a municipal wastewater treatment system, used antifreeze can be diluted thoroughly with water and poured down the drain, or flushed down the toilet. NEVER dispose of antifreeze down the drain if you have a septic tank. Recycle it instead.
Drained your Antifreeze?...
Recycle it or dispose of it properly! ANTIFREEZE IS HIGHLY POISONOUS
Antifreeze is highly poisonous to animals and people. Its sweet flavor attracts children, pets, and other animals, so always clean up spills, store securely and dispose of it carefully.
NEVER pour antifreeze down an outdoor storm sewer, on the ground or in a ditch, as it may drain to a lake or stream and harm fish and wildlife.
