Wastewater

When fats, oils and grease cool, they solidify and can create blockages in your pipes and the sewer system. These blockages may lead to basement flooding and sewage overflows onto streets and surrounding areas. They can also damage wastewater infrastructure, which can increase costs for the municipality and residents.

Common sources of fats, oils and grease that should never be poured down the drain include:

• Sandwich spreads
• Milk and cream
• Salad dressings
• Butter and margarine
• Sauces and gravies
• Meat fats

After cooking, allow fats, oils and grease to cool in the pan or in a container, then scrape them into the garbage. Wipe excess grease from pans and dishes with a paper towel before washing, and dispose of the paper towel in the garbage.

Many everyday items should never be disposed of down the drain. Even products advertised as “flushable” do not properly break down in the sanitary sewer system. These materials should always be disposed of in the garbage. 

Flushing inappropriate items can damage the sewer system and may lead to sewer backups in your home. 

Common hygiene items that should never be flushed include: 

• Personal care wipes, baby wipes and facial tissue 
• Tampons and sanitary pads 
• Diapers 
• Condoms 
• Cosmetics 
• Cotton swabs 
• Dental floss 
• Hair dye 
• Hydrogen peroxide and isopropyl alcohol 
• Nail polish and nail polish remover 
• Perfume and cologne 
• Waxes
