FOG Facts

What is FOG?

Fats, Oils and Grease. There are two types of FOG 

  • Animal or vegetable origin
  • Petroleum or mineral origin

Animal or Vegetable FOG

Animal or Vegetable FOG can block up sewer lines by building up on the sewer line walls eventually causing the line to become clocked causing back ups in the system.

This type of FOG comes from Homes, Apartments, Hotels, Childcare, and Restaurants. Restaurants are a significant source of FOG because of the amount of grease used in cooking and other food prep work.

Petroleum or Mineral FOG

Petroleum or Mineral FOG can cause harm to the biological phase of the City of Dallas sewage treatment plants. 
This type of FOG comes from Car Washes, Manufacturing Facilities, and Body shops.

How does FOG affect plumbing?

FOG can block your pipes by chocking your water flow, thus causing the water to back up at the source. Grease builds up in the pipe causing the ability of water flow to slow down or cause a complete blockage. Grease affects the plumbing in your home the same way.
