Why are mechanical repair wastes a concern in our environment?

If mechanical repair wastes go down the drain into the sewer system, they can cause structural damage to the region's sewer system. Some are highly toxic, even in low concentrations, and can cause harm to our environment.

Prohibited and restricted automotive liquids and wastes which can cause problems include:

  • Antifreeze
  • Oil and oil filters
  • Spent lead-acid batteries
  • Brake fluid and carburetor cleaner
  • Grease and other petroleum products
  • Used tires and other solid wastes

Proper management of these wastes will help ensure protection of the environment, human health and structural integrity of the sewer system.
