Colorado Springs, 2021: How Grease Hardens in Pipes and Why Kitchens Need Interceptors
Colorado Springs, Colorado, not the northern Front Range. On November 18, 2021, the city utility held a public demonstration, and KKTV reported how fats, oils and grease harden and block pipes.
The utility said clearing a blocked main line usually takes two to five hours, with a camera used to find the debris. Its supervisor warned that when sewage comes back up, it usually surfaces at the bottom of the house.
Lesson: grease belongs in the trash, not the drain. A kitchen that sends it down the line pays for it later. An interceptor catches grease before the sewer does, but only if it is pumped on schedule. Call the line and describe your kitchen. Also see hydro jetting.
