Tips to Keep Your Sewer System Safe

Residents can help keep the sewer system safe by disposing of chemicals properly and keeping systems blockage free.

Dispose Chemicals Properly

Dangerous substances include the following:
  • Antifreeze
  • Artists' paints, mediums
  • Brake fluid
  • Fertilizer

  • Insecticides
  • Lighter fluid

The following fatty items should not be put down the drains:
  • Butter and margarine
  • Cooking oil or shortening
  • Fatty food scraps
  • Lard
  • Meat fats
Other items to avoid putting down the train include:
  • Ashes, sand, mud
  • Baby care products
