Grease Traps

As part of our pretreatment program, St. Vrain Sanitation District offers a free grease trapper with disposable liners, which can be placed under the sink and filled with grease after cooking. When full, the liner may be tossed in the trash and new liners can be picked up for free at the St. Vrain Sanitation District administrative office at 11307 Business Park Circle, Firestone. If grease is poured down the drain, it can cause major problems in the service line, which is the responsibility of the homeowner. This grease trapper will help to prevent fats, oils and grease from plugging sewer lines, damaging your home and polluting the environment. Stop by and get yours today.

  • Great for disposing of grease from indoor grilling machines, stoves, ovens
  • Works as a “Grease Catcher” for outdoor gas grills
  • Great for storing cooking grease/oils

  • Never pour grease or oil down the kitchen drain
  • Never pour grease or oil into a toilet bowl
  • Put hot grease in the grease trapper inside the liner or
  • Allow grease to cool in the frying pan then scrape into the grease trapper or into the trash
  • Scrape food waste into a lined trash can not into the sink
  • Use a paper towel to wipe oil and grease from plates, pots and pans, Discard in the trash
  • Use a strainer to catch food scraps from going down the drain and empty the strainer into the trash




**Please put the following in the trash rather than down the drain:

  • Baked goods, butter, cheese, cooking oil, dairy products, fat from meat, gravy, lard, margarine, sauces,
    shortening and table scraps


  • Grease, fat and oil poured down the drain, sticks to the drain pipes and to the District's sewer lines.
  • Grease creates operational problems at the District's Wastewater Treatment Plant

  • Avoid having raw sewage go into homes, businesses, parks, yards, streets, ditches, rivers, or lakes.
  • Prevent an offensive and expensive cleanup
  • Reduce the potential contact with disease causing organisms
  • Eliminate the need to temporarily relocate living arrangements during cleanup and repair
  • Lower the District's maintenance costs to help keep sewer rates from increasing

  • Using hot water to flush grease down a drain is a waste of hot water? When hot water contacts the cooler piping, the grease comes out of the solution and sticks to the sewer line
  • Soaps and detergents that claim to dissolve grease may pass it down the sewer line and cause problems elsewhere
  • A garbage disposal does not prevent grease from going down the drain
  • Excessive use of drain cleaners will eventually damage the sewer line resulting in costly repairs
