What Are Some Problems Caused by Excessive FOG?
FOG, when it is put down drains in excessive amounts, coats the inside of pipes and gradually builds up till it blocks the flow of wastewater. FOG build up requires extra cleaning in sewer lines by City crews, and has caused blockages and sewer overflows in Yreka. FOG also puts a greater strain on the City's wastewater treatment plant.
