The acidic effluent from a failed grease trap travels down into the sewer system creating what the British lovingly call FATBERGS! This causes our infrastructure to fail AND adds hardship to the wastewater treatment plants. It can also put hardworking restaurant owners out of business for good.

Hidden costs of concrete grease interceptors

Corrosion in concrete interceptors
Sulfuric acid reacts with calcium hydroxide (Ca(OH)2), forming calcium sulfate (CaSO4) that, in the presence of water (H2O), creates gypsum (CaSO4ยท2H2O.)
“My experience has been that over time, as concrete interceptors deteriorate, you will see a decrease in pH right after they are cleaned due to scraping or pressure washing of walls.” AHJ Feedback
