Grease-related issues commonly arise within 300 feet of high grease generators, such as restaurants. Since grease emulsifies at 140ºF and dishwashers typically rinse with water at 180ºF, grease often bypasses grease traps and flows directly into the city’s sewer lines. As the water cools, the grease solidifies and blocks the line. Many restaurant owners are aware that running hot water can temporarily emulsify the grease, pushing it further down the line.
If there are no restaurants on the line, potential sources of grease buildup may include apartment complexes, schools, catering kitchens, food processing plants, or any location where large-scale cooking occurs.
Additional concerns arise in areas where sewer lines have sagged due to ground erosion or in siphons running beneath streams or bridges. These lines are especially challenging to clean as heavy debris (e.g., stones) can accumulate, trapping grease and worsening blockages.
A consistent EHC‑33™ treatment program can significantly reduce or eliminate these grease blockages, ensuring more efficient sewer line performance.
