Sanitary Sewer System

Sanitary Sewer System

The City’s sanitary sewer system collects wastewater from indoor plumbing such as sinks, toilets, washing machines and floor drains. Wastewater is transported through a network of underground pipes to a wastewater treatment plant, where pollutants are removed before treated water is discharged.

Protect Our Sewer System

What goes down the drain matters. Improper disposal of animal, household and yard waste can be harmful to the environment, hazardous to public health and may violate state and federal law.

Materials that should be properly disposed of rather than introduced into the sewer system may include:

  • Fats, oils and grease (FOG)
  • Paint
  • Pesticides
  • Fertilizers
  • Lawn and garden clippings
  • Animal waste
  • Cleansers and other household chemicals

What Goes Down the Drain Matters

Even some water-soluble cleaning products contain chemicals that can be harmful to aquatic life and water supplies. Proper disposal of household and business waste helps protect the City’s sewer system, the environment and public health.

Three-step graphic for proper fats, oils and grease disposal: scrape it, can it, and trash it.

Fats, Oils & Grease (FOG)

Fats, oils and grease can cause problems in the sanitary sewer system when improperly disposed of down sinks or drains. Residents and businesses can help protect the sewer system by properly disposing of FOG and keeping it out of drains.
